Title: Phase One IQ3 100mp. Shipping now.
Post by: Doug Peterson on January 03, 2016, 08:32:09 am
(https://digitaltransitions.com/wp-content/upload/XF-100MP-camera-system-profile-screen-web.jpg)

Channeling Steve Jobs here for a minute…

Today Phase One announces that it is shipping the world’s first 100mp camera, the first full-frame 645 CMOS camera, the first 16-bit CMOS sensor, and the first HDMI enabled digital back. These are not separate products; it’s the Phase One IQ3 100mp.

This is not an announcement-of-an-announcement. This is not a preview or a prototype. The IQ3 100mp is shipping*. In fact we have the tracking number of our demo units and appointments available.

- Full Frame 645
- 15 stops dynamic range
- CMOS Sensor
- ISO 50 to ISO 12,800
- Electronic First Curtain Shutter
- HDMI Output (e.g. live view with a 7” battery-powered display untethered)

Read more at our Phase One IQ3 100mp (https://digitaltransitions.com/xf-100mp-camera-system/) page. We'll also have two articles up later today with more details!

As always, if you have any questions don't hesitate to email me or put them on this thread. Some answers I suspect I won't be able to provide until our units arrive early this week. But some I should be able to get by speaking with the R+D team.

Also, this will be our most tested back ever. You may remember our several tests of the IQ250 including ISO ramps, long exposure tests, and a massive Tech Camera Lens test in which we tested nearly every popular tech cam lens with five different Phase One digital back models. We'll be doing even more testing of the IQ3 100mp. So if you have testing requests, please feel free to email me or put them on this thread.

*I'd expect this back to be quite popular and go into back-order within days

I would to know how this back responds to lens cast with Rodenstock lens, especially the HR 40mm and HR 32mm. 

Long exposures capability is defiantly of interest to me. 

How does the color look compared to the CCD counterparts? 

Is the base ISO 50, or is it 100 with the option to pull the ISO down to 50?   

What is the noise structure at higher ISOs like?  I always found the noise on Canon sensors to look quite ugly once you got to ISO 250 ~ 320. 

PS. With the HDMI Output, is the end goal to also offer video (or does it already)?

This is good news.
Full 645 and HDMI will be appreciated by the customers.
HDMI makes tech cam use much easier.
And of course prices of existing MF gear will go down.

Congratulations with what most likely is a very nice camera solution for those who need the high resolution. I'm a bit weary about the '16-bit color' claim, but we'll see once the Raw files become available if that really means a (as advertised) 15-bit ADC pipeline converted to 16-bit/channel output. The new higher MP resolution IQ3 backs are advertised as 13-bit, and the CMOS 50MP as 14-bit ...

I'm also interested in learning about the sensor array's physical size, and resulting photo-site pitch. That will determine several aspects of lens suitability and postprocessing (Capture sharpening) needs.

The current documentation only mentions an IQ3 50MP, IQ3 60MP, and IQ3 80MP back. So does this mean that the 100MP comes only as a complete XF camera solution, or will there be an IQ3 100MP back as well?

Cheers,
Bart

I can't speak to "end goal" as that sounds very open ended. But today the goal is to provide a fourth* way to view Live View. It is possible to record the HDMI signal; however, most of the accoutrements of a true motion/video/cinema system are not there. For instance the white balance and exposure of the live view are both full-auto and not adjustable.

If you have a strong interest in adding such features to turn this into a more fully featured motion system I suggest making your voice heard. That said, my gut feeling is that it's best for Phase One to stick with doing stills exceptionally well, rather than spend time doing motion pretty well.

Interesting.  This is probably my dream sensor.  100MP, CMOS for live view and ability to shoot high ISO's.  I'm also a little upset.  I just moved to Phase One in June when I ordered the XF and IQ380.  Well I did not receive the IQ380 until first week of November (almost 5 months after I had paid for the system) and now they come out with this.  I wonder if I could make a good argument to allow me to trade it in.

An H platform IQ3 100mp is planned for Q2 of 2015.

At this time no V or C version is planned. Not that the Hassy 500 series lenses could handle 100mp anyway.

I suspect the vast majority we sell will be on an XF platform. The modern design and features of the body, integration with the IQ platform, 5 year warranty (when purchased with an IQ3), and lens lineup are very appealing.

Us too! One of our top priorities is a full suite of tech camera tests.

Long exposures capability is defiantly of interest to me. 

It looks like this one will be very very strong for long exposures. Tests forthcoming.

How does the color look compared to the CCD counterparts? 

I don't think that's something anyone can ever really answer for anyone else. But we're glad for you to come make your own color evaluation.

See the Phase One IQ3 100mp in LA (https://digitaltransitions.com/events-training/come-see-the-new-iq3-100mp-in-los-angeles/)

Is the base ISO 50, or is it 100 with the option to pull the ISO down to 50?   

This is a normal ISO, not an "extended" ISO.

Thanks, I'm sure the link and PDF will eventually update to show this as well, but no luck so far.

A 4.6 micron pitch will mean that at f/5.0 or narrower, diffraction will start to function as an OLPF of sorts, to reduce aliasing effects even further than the dense sampling already does, and apertures of f/16 or narrower will lose effective resolution due to diffraction (MTF falls to below zero at the highest possible resolution).

It becomes even more important for Capture One Pro to add deconvolution Capture sharpening to its feature set, despite the sensors not having OLP filters.

Bart

I can't find any reference to the sensor manufacturer on that page.

Edit: found it (why do web designers insist on having you click to get the text?):

Phase One and Sony have been development partners for years, the 50MP sensor being the first milestone of our cooperation, now found in the XF IQ3 50MP. Creating the full frame sibling to the 50MP CMOS system has been a top priority of Phase One for years. Phase One sensor experts have been working hard to optimize the complete use of the 100MP sensor for the worlds most demanding photographers.

So it is a joint development. We'll see if that also means the sensor is a Phase One exclusive.

Joe, shifting wide angles has been the Achilles heel of MFDB with every back after the P45+.  When I tested the 80mp back against the 60mp, I found the 80 to be totally unusable with my wide lenses (the Schneiders).  I just couldn't get into the 32 and 40 HRs given how big, heavy and expensive they were combined with the distortion they exhibit.

I don't know, though... I'm really intrigued about this new back and I seem to find myself using smaller and smaller shifts too.  It has me wondering about shooting the XF and just cropping for composition instead of shifting.  For that, the 28 would be essential... is it any good?  I wanna see some tests and more info about the 16bit pipeline of course, but I'm very intrigued.

Exactly, and some Keystone correction combined with the improved rescaling algorithms of Capture One Pro 9 should go a long way with plenty of pixels to start with. When Deconvolution sharpening would be added into the mix of future C1 improvements, I can see people changing their workflow to solving these issues in postprocessing, rather than at capture time.

Hi,

Exceeding 14 bit seems like an engineering feat. Would be interesting to hear if it back side illuminated, like the A7rII sensor as BSI seems to reduce the cross talk problem.

Electronic first shutter curtain is a good feature, if they can integrate it with the shutter in the camera that is.

Great news for MF-shooters to have a full frame CMOS sensor!

Best regards
Erik

Chris, that is probably the one point I am most interested in and may be disappointed by.  However, the new Sony's (on their A7r line) are back illuminated, giving greater lens cast response.  Hopefully this is the case here. 

Insofar as the 16-bit CMOS claim, I am a bit skeptical.  Leica advertises that the new S2 is 16-bits, but I have a really good source who tells me it is really 14-bits amplified to 16-bits. 

Leica does not source their sensors from Sony though, and considering Sony's recent track record on groundbreaking sensors, I would not be surprised if it is a true 16-bit sensor.

I certainly would hope so.....  I had hoped that the trade in would be more aggressive.  Anyone, though, who bought an IQ3 80MP CCD back is really going to feel the pain..... regardless of the upgrade policy - unless Phase just swaps the backs...... good luck with that one.

Well I have to think carefully about whether I ditch my 42MP Sony outfit, my 50MP Hasselblad outfit, sell the house, get divorced and spend a minimum of $50k to buy this.  To be honest I do not understand why we need even more MP when we have such good solutions already.  As a business person who has watched the value of my "investment" in Hasselbad vanish I will certainly not be considering switching to this.  There may well be a few pro's who genuinely need 100mp and can easily afford it but I suspect that there will be many more well healed doctors and dentists who cannot resist the temptation to buy.

Oh by the way the A7RM2 is now selling for sub £2000 on Ebay as a new item.  Great camera, works well, nice lenses, light and you know what I can carry it wherever.

Wondering out loud, with the Electronic First Curtain, I wonder how the 1/1600th LS sync is going to change/improve.  It's really a wiring issue, in that your strobe has to be really freaking quick with the fire, and doing it wirelessly is gonna kill batteries.  In theory, wouldn't you be able to shoot the leaf shutter at 1/800th and trigger the first curtain during the exposure by the lens, giving you a shutter of 1/1600th or faster? It wouldn't work with a focal plane as your ambient would increase as the second curtain closed.

To be honest I do not understand why we need even more MP when we have such good solutions already. 

When it comes to data, more is generally better. However for most applications, the increase from 80 Mp to 100 Mp isn't such a significant gain in resolution (only 12% more pixels in the linear dimension) and you're quickly diffraction limited in any case. But size definitely matters - having cut my photographic teeth on 6x6 film, I'm not a fan of crop sensors. Thus the CMOS sensor in the full frame medium format for me is causing a major relapse of G.A.S., which for some silly reason I thought I had overcome. Luckily, the prospect of my wife shooting me (and putting me out of her misery) for even thinking along these lines, if not a cure is a pretty effective treatment. For now. I think...

One thing that must be observed, is that the pixel size of the new Sony sensor measures equal to the 42mp FF sensor that is used on the α7rII... Is it a coincidence? Is it the same senor but tweaked? ...or is it a simple resize of the image area?

leaf shutters have shutter leaves closing in a manner that they can't use EFCS, where sensor starts exposure row by row with vertical shutter blade following that process with some delay and mechanically shielding the rows for which exposure is over...

and they typically do not produce much shutter shock at all, if they are symmetrical enough.

I look forward to your analysis! Here are a gig of raws to play with:
Phase One IQ3 100mp raw file download (https://digitaltransitions.com/xf-100mp-camera-system/#raw)
Doug thanks, I'm downloading the updated C1 9.0.2, but the files link is perhaps sent by email (and I couldn't enter a non USA location, if that matters)? I'll probably also have to wait for RawDigger to recognize the new Raw file format/size.

Okay, if I assume that RawDigger (RawDigger-1.2.3.435-x64.exe) reads the ISO 50 sample file correctly, then this is what I find:

ReadNoise (standard deviation)
R=5.04
G=5.04
B=5.03
G2=5.02

Blacklevel
Offset=1024 (automatic, the mean of the masked pixels is 1025.7, 1025.2, 1025.4, and 1025.4)

Saturation
R=65532
G=65532
B=65532
G2=65532

So for Dynamic Range I get for the green channels Log((65532-1024) / 5.03) / Log(2) = 13.65 stops dynamic range, instead of 15 stops. I'm not sure if the camera's 14 or 16 bit mode was used for this shot, but 13.65 stops is still impressive.

Again, this assumes that Rawdigger reads the file data correctly, and that the masked photosites contain only read-noise (QED).

Cheers,
Bart

It's slightly worse than the IQ250, despite that this IQ250's darkframe was shot at warmer temperature. I don't know how he calculated the standard deviation for the IQ3 100MP.

For this IQ250:

ReadNoise (standard deviation)
R=3.34
G=3.55
B=3.39
G2=3.53

ln((65535-1024)/3.4)/ln(2)
=   14.2 stops of DR

Hi,

The Read Noise you've shown, is after subtraction of the Black point, but the masked photosites are already without blackpoint offset bias. When you subtract the bias again, the left tail of the standard deviation gets clipped to 0, and the SD of the now clipped Gaussian distribution is under-represented.

Bart

Do you mean I should read the numbers when I manually set black level to 0 for each channel?

Correct, that's what I did anyway.

Oddly, when I do not subtract the blackpoint from the 100MP, the saturation values are all the same, and they are all different from subtracting a fixed amount from all color planes. MAybe RawDigger needs to be tuned a bit for this new file format.

In your way of calculations the IQ250 scores 13.2 stops of DR, which is slightly below your 100MP score.

Keep in mind that if you export the IIQ file with Capture One into dng format then re-open with RawDigger you could get a different distribution of darkframe noise. I haven't played with that yet. I will see to the real-world dynamic range tests. The first thing is to identify the highlight headroom for the 100MP then decide how much aperture to compensate for a comparable ISO. For example, ISO 35 and ISO 100 are essentially the same for the IQ180. Not sure whether ISO 50 and ISO 100 will be the same for the 100MP this time.

I wonder how this new sensor will do with the tech lenses though, the smaller pixel pitch is worrying, but on the other hand if it's BSI maybe it's less bad than the IQ250 anyway. The larger sensor size will require larger shift amounts too though to avoid the feel of limited movement range.

Hi Doug,

What I've seen sofar (one file, perfectly exposed at ISO 50), it looks impressively nice in Capture One Pro 9.0.2. At f/8 there was only a very little evidence of aliasing but hardly noticeable, and noise was very low (even without noise reduction).

The math is just to verify the 15 stops DR claim, which seems a bit high at this point into analysis. I'm also still in the process of finding out how the 14 or 16 bit mode settings affects all this.

Bart

Its not like all of the sudden the older backs have stopped working. The were used to produce amazing images then and now. This new sensor however is a monster. I am very eager to see results with tech camera lenses.

If it is as it usually is, the "real world DR" is relying heavily on software noise reduction in the raw converter. That is you reduce noise and virtually improve DR at the cost of detail and color fidelity. A trick that's quite hard to detect for the layman, but it's still a trick.

If they state 15 stops of DR in the data sheets, like they currently do, I hope it's something substantial behind it so it's not the "16 bit color" all over again. To start with the file format must have changed slightly so the files actually contain 15 bits, as the old IIQ is just 14 bit expanded to 16. If it had changed I'm surprised that rawdigger could read the files at all, so I'm very skeptical about this number.

The the DR thanks to aggressive noise reduction may appear to be better than it is I find most likely though. You probably can't turn off the base noise reduction in C1, "turning off" noise reduction usually just means that you turn off a second layer of noise reduction. The base layer can be quite aggressive too.

One of the perks of the job is doing my wedding photography (http://www.doug-peterson.com/p829532778) with Phase One gear (along with Fuji or Canon as a second camera).

Having the leaf shutter lenses is absolutely game-changing for what kind of light and lighting you can use at a wedding. That's a big deal because even our 10k systems feature a full line of leaf shutter lenses. If you'd ever like to arrange a test just let me know :).

Yes there's a second hand market, I'm myself one of the poor people :), I'm still on 50MP Kodak CCD.

What I mean is that I think we'll see a very quick reduction in new sales of the CCD backs, like the 44x33mm CCD sensors quickly lost its sexiness when the 44x33mm CMOS appeared. I don't think we'll hear much of the old "there's some special look to the CCD", as high end new products it won't survive for long. I would not be surprised if IQ4 will be CMOS only.

It might be controlled by price though at $44k there's plenty of room below, but soon Hasselblad and possibly Pentax will come with their offers which may make it difficult to sell CCDs as a low cost alternative.

I generally take zero stock in the absolute number any company/website/person assigns to dynamic range. They can be using whatever definition they choose.

Do they mean where you can see the line between a black patch and a darker patch in a ramp target? I don't shoot targets. I shoot people. Moreover I don't care if I can see the patch. I care about things like how much grain/noise is there when I pull up the shadows, and just as importantly what is the structure and aesthetic of that grain/noise (is it clumpy? finely distributed? colorful? monochromatic?). How accurate and natural is the color in those shadows?

Moreover I don't give two figs whether it's accomplished in hardware, firmware, software, or sorcery. So if the dark frame and secret sauce of Capture One is (as it has been in the past) part of the final result, I really don't care.

I care how the final image looks. That's it. That's why I say we'll have real world comparisons up later this week.

What I DO find interesting is Phase One claiming one stop MORE dynamic range than their previous highest. That's very promising given how very very good the previous highest was.

Yes it's very interesting, but I do mind how it's achieved. I've analyzed hifi stuff both audio and photography quite extensively and I know how easy it is to fool oneself. If you stare at one property alone you miss something else, classical example noise reduction, if you stare at the grain you miss that details are smeared or colors are pastel like.

It's also very subject dependent, it may look good in one image, and worse in another... if you really want to know how a system performs you need both, you need the hard engineering facts and you need real life tests. If you only go for a week with unstructured laid back "real life tests" it may grow on you over the next year that the system isn't actually performing as you initially thought. Pairing "real life tests" with independent expert testing gives you (at least me) better confidence that the product really delivers as advertised.

Personally I think this DR thing is a way over the top exaggerated "need", but I understand as much that it makes sales just like megapixel number does. I do expect this new back to be excellent just like any other recent Sony sensor, but if it's actually better than the already excellent IQ250/645z/CFV-50c remains to be seen.

MFD is afterall much about "keeping the distance" from 135 gear, and today this is done with two hard numbers, megapixels and DR. 100 and 15 are two really good numbers for now :)

If it's really BSI then there is a possibility that the discontinued Schneider 28mm XL might work with it with acceptable color cast! Not sure about astigmatism/curvature/smearing caused by sensor cover glass though.

Hi Anders,

Would be interesting how Phase One defines DR. If they use the DxO print rating it is quite obvious that they reach 15EV, 100 MP downsampled to 8 MP. If they use DR at pixel level, 15 EV would be quiet a feat using a Sony 4.6 micron sensor.

Just to say, using the DxO print rating is quite OK, as long as it is clearly stated. Phase One could also state an SNR of 90 dB, that would be pretty clear and quite impressive.

Personally, I feel that Phase One has been talking a bit to much about 16 bit files, which makes a lot of damage to their credibility. But after all, when all the chips are down, it is image quality that matters and if Phase One delivers on that it is quite OK. And I am pretty sure they deliver.

Best regards
Erik

I don't know about the complicated maths, but physics says that if the sensor has the same pixel quality as the smaller one then image S/N should be better for the same size print. In layman's terms, that translates to better practical DR, although engineering DR is a different thing.

So if Doug chooses to say that you get more back for your money, I would have no problem with that.

What I find interesting is how Phase prices climb higher and higher. Doug certainly hopes to get more money for his back.

But it is essential to understand how to do a proper comparison of dynamic range. Preferably I would hope for the same headroom for highlight recovery, with some details in deep shadows to push. If ISO 50 is indeed an extended ISO just as what is with the IQ3 80MP, then you might end up over-exposing the IQ3 100 MP by a stop, leaving less highlight recoverability and cleaner shadows.

To make this precise, I would hope that two images have very similar level readings for highlight area (e.g. sky) in Raw Digger, e.g. both about 58000 out of 65535.

It would be interesting to include the CCD backs as well :)

With my DCamProf color profiling work I've looked at a few Sony high end CMOS sensors and their CFAs are if not identical very highly similar. You can use a A7r2 profile on a Pentax 645z for example. I never made any real attempt to actually find out exactly how similar they are. I very much doubt that Sony make custom mixes for different manufacturers though so I think all products based on the sony sensor of a particular model have the same CFAs, but the IR filter response can differ of course.

IMO, while this is welcome advancement, Phase One have put themselves into a corner for a competitor to emerge.  Sony has Phase One by the boot straps with sensor development as they have demonstrated they will sell the same sensor to anyone (Pentax rocked the 50MP implement for a lot cheaper) and if their contract allows them to use the sensor and SONY releases a mirrorless MF camera with interchangeable lenses, it will be tough times for Phase One. I personally don't ever want to own a camera with an optical viewfinder ever again as I think their are some incredible tools gained by mirrorless for landscape work and I enjoy the smaller size for traveling.   I really do think Sony could release an MF camera this year.  Will it be as fine tuned as a Phase One probably not but it will probably be incredible for the price advantage.  We all want incredible cameras with the best IQ but at $48K, there is an awful amount of room for Sony to step in and make a move.  Even if they came out with an 80MP CMOS mirrorless MF camera and charged $24K, it will take a lot of business from Phase One.  I am grateful I sold my IQ180 this last year and have been pleasantly surprised at how nice the photos from the A7RII with OTUS lenses are.  Some disadvantages but the Sony is so much more capable in multiple circumstances.  Still waiting for the day I get a digital 617 camera.  Your thoughts?

For those that aren't quite following the math-oriented digging around of raw file offsets...

DT will have real-world dynamic range tests available later this week. That is, photos, showing the visual difference.

The DR that Bart measured is the engineering DR. Photographically useful DR is less, since a SNR of 1:1 with engineering DR is not useful photographically. Photographic DR depends on the noise floor used for its determination but is typically a couple of f/stops less. For example, the engineering DR of the Nikon D810 at base ISO is reported by DXO at 13.67 stops. Bill Claff (http://www.photonstophotos.net/Charts/PDR.htm) reports the photographic DR of the D810 at 11.53 stops.

Since the new MF chip is 2.5x the area of the D810 and of a newer generation, but I would expect that its DR would be no more than 1.5 to 2 stops greater than the D810.

We sold 50mp CMOS backs at a faster pace after the introduction of Pentax 645Z than before. It was one of our most commonly traded-in cameras.

Medium format is a niche. It's a small small percent of all cameras sold. So any competition, marketing, or awareness raising, helps everyone in medium format with a strong product. Our hardest task, by far, is getting people to come take a picture with our camera; once they are looking into any medium format solution (of any brand) they are far more likely to do so.

I doubt that... There are so many pros that value DR more than anything and 25mp are more than enough for most of their work... In fact the better of the best wedding pros, (just comes to mind as an example, other pros too...) wouldn't want to shoot with 100mp... It's also the capacity of the card to consider (other than keeping DR and decreasing size of files) for many pro tasks...

I agree that it brings more awareness.  Do not get me wrong, I really hope MF keeps going but both the Phase One and the Pentax are optical viewfinder cameras and while some people will use this back with technical cameras (assuming it works), the door is wide open for someone, probably Sony, to introduce a mirrorless camera with the same sensor at a far cheaper price and smaller package.

Geeezus Guys.

The handful of usual suspects are already on the prowl and looking to have PhaseOne's head on a platter. Ok, step back for a second. This is a 100MP CMOS full frame 645 (40.4mm x 53.7mm) back with the latest (or at the very least very recent) SONY CMOS sensor technology. It has twice the MP of the previous SONY MF sensor and a larger form factor.

You guys need to chill out and head out and make images for a change.

Yunli, you have some awesome images on you 500px. The ones using the D4s and the IQ260 are superb among others. At the very least the new Phase 100MP back is gonna be as good or most likely a lot better regardless of whether it has 13.1 stops or 14.99 stops of DR or whatever. It is gonna have much more color sampling due to more pixels and if they are as good pixels as the one in the 50MP Sony sensor (or even if they are sightly worse, possible better!) there is just a lot more of them. Its gonna be splitting hairs regarding per pixel quality.

FPS or SPF?

It has both a focal plane shutter and a line of leaf shutter lenses.

I don't know what an SPF is, but I'd recommend against using this back as sunscreen. It won't cover much of your skin, even with the larger lenses mounted.

Stabilized lenses, or sensor?

No.

Focus speed, Focus Tracking, Multi Point Focus or PDAF Track Focus?

Focus speed on the XF is very good and it has a continuous mode for tracking. You'd have to test it and tell me what you think. We have Phase One open houses in LA and NYC (https://digitaltransitions.com/events-training/) this month, or you could set up a remote evaluation.

Single point AF, no PDAF Tracking. You can capture from live view, whether using the zoom-to-fit or zoomed-to-100% mode.


With HDMI out, does this allow for motion imagery, and if so Specs?

See earlier comments. Not really intended for motion, but if you want to you could record the HDMI signal which is up to 1080p.

Useable ASA?

"usable" means something different to everyone. Printed 36" wide I personally would be happy with ISO6400 from what I've seen so far. But I don't mind grain if it is well shaped and free of color and weird artifacts.

Download the raws and make up your own mind. Phase One IQ3 100mp Raw File Download (https://digitaltransitions.com/xf-100mp-camera-system/#raw)

Articulating LCD?

No. But wifi to any iOS device and HDMI out so feel free to put an iPhone or iPod touch or monitor wherever you want.

Hey Guys,

So, I have a question.  I have had this question for awhile and always thought that if/when a new bigger back was introduced (like this new 100MP back), that medium format "full frame" would actually mean "full frame" akin to the definition and terminology used in comparable DSLR vocabulary.

Looking at the specs...

40MP back = 43.9mm x 32.9mm
50MP back = 44mm x 33mm
60MP back = 53.9mm x 40.4mm
80MP back = 53.7mm x 40.4mm
100MP back = 53.7mm x 40.4mm

Original 645 film frame = 60mm x 45mm

It seems the 60, 80 and 100MP backs are all the same size, yet not quite full frame, although they are called full frame.  And by full frame, I am referring to the original 645 film frame size of 60mm x 45mm.  In actuality, the 60, 80 and 100 are 80% of full frame (by area).

Much in the way the DSLR's use the term "full frame" to be the exact size of an original film frame size of 36mm x 24mm, can we expect this medium format term of "full frame" to equal this "almost" full frame size?

Don't get me wrong, I am completely enamored that Phase One appears healthy and innovative and that is great for medium format and all of us.  It was just a question that I always had and thought this would be an opportune time to ask.

Thanks!

Hi Bill,

Yes, engineering DR is what I calculated, but with such low read-noise, the look is somewhat similar to photon shot noise at low intensity levels. So I'm not too sure about the otherwise assumed few stops less DR for actual photographic use. And there is also software noise reduction available tp improve visual/photographic DR, which is therefore much harder to define than engineering DR, IMHO. The (lack of) structure in the read-noise is also an important factor as to how far one can push shadows, if they need to be pushed at all.

And as you said, the downsampling to a common output size also helps the IQ3 100MP to improve the apparent/photographic DR.

What I've seen so far looks really nice, with tolerable noise despite low exposure (=relatively high photon shot noise) levels. And the benefit of a physically larger sensor is still that a higher MTF can be had for the same features that would be smaller on a smaller sensor for the same field of view.

Cheers,
Bart

This is where you went astray.

No 645 film camera ever exposed an image on film which was 60 x 45mm.

The "film gate" of the Mamiya 645 (i.e. how big the picture, as exposed on the film) is the benchmark used by Phase One.

Stepping back, the relevant thing here is when you use a "crop" sensor back you have to put a mask in the viewfinder. With a "full frame" back like this one there is no need for a mask. What you see is what you get.

Exactly, the gate on 645 film is about 56x42mm IIRC. No need to use viewfinder masking when using the phase 60/80/100 mp backs on a 645 body.

And Guys, again geez, it is best to have the choice of 100MP if one wants/needs it. There are many awesome cameras out there to choose from.

Choosing a camera is a very personal choice.

I own several and choose according to the job at hand. It is obviously not always about more MP in fact it is sometimes better to have less. There are lots of factors to consider. But at the end of the day it is cool that Phase has the new IQ 100MP back available.

For that I do not doubt :) I'm sure it's the king of sensors as of now!

There are so many "if"'s for me: if it's BSI, and if it works with the Schneider 28mm XL, and if I can find a reliable ND solution for that 112mm center filter of the 28XL (leakage-free), and if I can manage to find a good copy of the 28XL, or if Rodenstock makes something else that is compatible and compact and wide enough (doing a better job than the 32HR) then... it's going to be impossible to resist  ;D Nevertheless, if the 32HR works with it then I'm sure many tech cam users will be happy with it.

I keep offering up to folks in my local market to give it a try - not had a single taker yet - and that was with the 5DsR and the 645Z to shoot along side my H4D-50.  Given the new high megapixel offerings, it really needs to be driven home that all pixels are not created equal, and the only way to see it is in print.

Interesting to see if Leaf gets the 100MP chip, or if they just do a firmware 'update' to change the color render.  I would wager that Phase has an exclusive period on the chip, wouldn't be surprised if it was 12 months.

I think the new HDMI out will be a huge addition for learning videos - literally see what the camera does as the photographer / art director / etc work live on set.

Having the leaf shutter lenses is absolutely game-changing for what kind of light and lighting you can use at a wedding. That's a big deal because even our 10k systems feature a full line of leaf shutter lenses. If you'd ever like to arrange a test just let me know :).

Hardware pixel binning is preferable to software binning (e.g. Photoshop downsizing). For example, consider 2x2 pixel binning as discussed  here (http://www.andor.com/learning-academy/ccd-binning-what-does-binning-mean) where four pixels are combined into one. If this is done in hardware, the 4 pixels are shifted into one prior to readout, and there is only one read noise contribution. In the case of software binning, 4 read noises are involved. Since read noise is so low with the new CMOS sensor, the advantage of sensor plus over software binning would be less than in the case of a CCD sensor with relatively high read noise.

The cited example is monochrome. Hardware pixel binning is considerably more complex with a color Bayer array.

There is just one problem. Lenses. Several of the Pentax newer 645 lenses are made to cover the 33x44mm format, just. IIRC the 28-45mm zoom is for 33x44mm sensor only. Ironically the older 645 lenses might work nicely although I would not expect them to get the best out of a 100mp sensor.

Yes, Pentax might not be able to pull it off with their lens lineup without introducing some others.  I think we are more likely to see a Sony mirrorless MF camera with Zeiss lenses and adapters for all sorts of MF lenses and possibly a Fuji MF camera as I believe they are looking for a ways to one up their APS-C based mirrorless line and possibly skip 35mm FF mirrorless as it would undermine their X series cameras.

With my DCamProf color profiling work I've looked at a few Sony high end CMOS sensors and their CFAs are if not identical very highly similar. You can use a A7r2 profile on a Pentax 645z for example. I never made any real attempt to actually find out exactly how similar they are. I very much doubt that Sony make custom mixes for different manufacturers though so I think all products based on the sony sensor of a particular model have the same CFAs, but the IR filter response can differ of course.

Ok, so if this is true, then we can reverse that process, and use the new IQ3-100 profiles on a Sony A7R2 in C1 9.0.2 ?

Getting to use ultimate quality Capture One profiles for a modern Sony sensor will be great. Yes they make 'generic' ones for A7R2 already, but if the ones from a new 100Mp Sony CMOS back are cross-usable for A7R2, then we should see an improvement, as Phase One refine their own camera's profiles to the Nth degree, whereas I have always had a hunch they don't do that with other manufacturers camera profiles.  (they are usually better than Lightroom, but not up to their own IQ backs profiles quality, imho)

[Edit: I just tried it, A7R2 files are indeed marginally better processed using IQ3-100 profiles - requires about 500k more to the K temp settings, but gives slightly more neutrality overall, a bit cleaner grays/whites/shadows plus slightly better shadow detail. It's a very fine difference, but I will set it as the new default for this camera now.]

Post by: BJL on January 03, 2016, 10:19:21 pm
Actually, the film image of 645 is 56 x 41.5 mm, so the sensor is getting pretty close to "full 645 frame".
While we are splitting hairs over dB of DR and format sizes: even if "645 film format" was up 56x42mm depending on brand, mounts for transparencies cost about a mm along each edge, and printing with enlargers usually costs a bit off the edges of the image that digital printing does not, so yes: 53.7x40.4mm is close enough that we can all stop worrying about the dreaded and despised "digital crop".

My question is whether this sensor is for Phase One only.  With the previous Sony 44x33mm CMOS sensor, it seemed that Sony was selling to all possible users in order to get enough sales volume, so is it the same this time, or is Phase One dominant enough in the "full frame 645" that it has negotiated an exclusive, the way it did with several Dalsa sensors?

My question is whether this sensor is for Phase One only.  With the previous Sony 44x33mm CMOS sensor, it seemed that Sony was selling to all possible users in order to get enough sales volume, so is it the same this time, or is Phase One dominant enough in the "full frame 645" that it has negotiated an exclusive, the way it did with several Dalsa sensors?

One of the perks of the job is doing my wedding photography (http://www.doug-peterson.com/p829532778) with Phase One gear (along with Fuji or Canon as a second camera).

Having the leaf shutter lenses is absolutely game-changing for what kind of light and lighting you can use at a wedding. That's a big deal because even our 10k systems feature a full line of leaf shutter lenses. If you'd ever like to arrange a test just let me know :).

Hey Doug,

I'm very much a natural light guy so leaf shutters don't really matter for me. I'm using a 645z & 1Dx's at weddings and it works very well. I'd love a larger chip phase one but when I tried the phase ones the demo p65+ I was offered which fit the budget was just too slow and the full frame xf series was too much $$ - I'm sure I'll get there eventually but not right now :)

Ok, so if this is true, then we can reverse that process, and use the new IQ3-100 profiles on a Sony A7R2 in C1 9.0.2 ?
if you believe that CFA is the same for 100mp (or 50mp) as for A7R2 then you can simply rename the profiles (the file names) in C1 and use them right now...

Hi,

Except that it is 100 ISO.

Just to say, low base ISO can be a good indication of large well capacity. Or non permissive filters, or low quantum efficiency.

Best regards
Erik


I would expect the samenbase Iso as A7r2 which I think is 200.

Could be the case... Surely Hasselblad seems to be moving their 50MP sensor as to be their entry level product which means that they are making space for larger sensors... Whether that will be the same Sony 100mp sensor or other remains to be seen... Also, the timing of the pricing policy suggests that these higher up sensors shouldn't be long before they appear...

Never the less, if Hasselblad uses the Sony 100mp sensor as well, that will mean that the MS versions will be of ...400mp of "true color" for the 6x version of the back...

Phase One IQ3 100mp Technical Specs (https://digitaltransitions.com/xf-100mp-camera-system/#specs)

1.4 frames per second in 14-bit mode
0.7 frames per second in 16-bit mode

Interesting, the 16 bit mode is probably new and may really produce 16 bit data in the raw files. Maybe those 15 bits of DR is true afterall :)

Yep, but IR filter is almost certainly different so the response is not exactly the same even if the CFA would be identical.

It should be noted that even if CFA is quite different normal low saturation colors will look sort of right anyway, to really see if there's a match you need to test high saturation colors.

All modern cameras today have quite similar CFAs. I've tested a fair bit of cameras and only my own Kodak based H4D-50 was substantially different within the "normal" range, as Kodak has built in quite some subjectivity into the CFAs itself, while all modern cameras are more designed to make objective realistic colors. Regardless you can still make hugely different results depending on profile design, just compare Leaf and Phase One color, despite the same sensor they have quite different color. Leaf ICC profiles can't be used with other cameras as Leaf has it's own processing pipeline with its own way to format their ICC profiles, nowadays builtin to Capture One. Otherwise you could switch between Phase One and Leaf color easily, but due to the different software handling of color you can't which is a good thing for Phase One so the products are more clearly differentiated.

What comes to my mind is that Sony sensors use ramp type ADCs. My take is that they can have different depth using different integration times.

Doug, why sensor + isn't used on P1's Cmos backs? Is there a (technical) reason for that? Personally, I find it the most attractive feature of P1 backs...

Sensor+ requires hardware support from the sensor and is Dalsa-specific technology.

Post by: torger on January 04, 2016, 04:15:53 am
For that I do not doubt :) I'm sure it's the king of sensors as of now!

There are so many "if"'s for me: if it's BSI, and if it works with the Schneider 28mm XL, and if I can find a reliable ND solution for that 112mm center filter of the 28XL (leakage-free), and if I can manage to find a good copy of the 28XL, or if Rodenstock makes something else that is compatible and compact and wide enough (doing a better job than the 32HR) then... it's going to be impossible to resist  ;D Nevertheless, if the 32HR works with it then I'm sure many tech cam users will be happy with it.

I think you can forget the 28XL. The A7r-II is BSI with the same pixel pitch and it didn't perform as well as we hoped for tech wide angles. My guess is that this Sony sensor is not BSI (as BSI and the best low ISO DR doesn't seem to combine right now) and that together with the small pixel pitch will not make it work well even with moderate tech wides, I'd be happily surprised if it can do the 32HR with any larger amounts of shift. However as it will for sure have offset microlenses it could still work well for unshifted center frames.

This is all guesses though, I wait eagerly for the first test reports.

Unfortunately I never got any raw files in that thread so I don't really know for sure, I've just heard several say that it's not solved the issues of the A7r. So I don't really know where the limits are.

As the sensor has microlenses I expect shading (microlens ripple) be an issue, but it can generally be fixed with some software tricks. Crosstalk is harder to fix. BSI should in theory have much lower such issues, but it depends on your design target on how you make the sensor. Tech lenses haven't been in anyone's design targets in recent years.

I think that to make it work well with tech lenses you'd need to make the photo diode a bit smaller and thus hurt DR/noise performance a little, and that is not a tradeoff the manufacturers want to do, just like we're probably not going to see microlens-free sensors again in the nearest future.

I think the tech lens ranges will have to adapt to the sensors because the other way around won't happen, unless we get a good match due to some coincidence. I hoped that BSI would be one such, but the A7r-II made me doubt.

I would not be surprised if Rodenstock is already working on some new retrofocus wide angle to work with modern CMOS sensors. Say if this new back won't work with the HR32 that would be a major blow to the tech cam genre for architecture and landscape and only Rodenstock can fix that, Sony won't care. With the lens design getting closer and closer the SLR lenses it remains to be seen if they can keep up with the image quality advantage, especially since they must do it without software lens corrections. If they succeed it would be a $10k+ lens (and probably 1kg+) for sure...

But let's first see what this back can do with the current lens ranges... I can't wait to hear/see about it  :)

Yes I completely agree. If you can just use keystones to fix an unshifted 100 MP image (with proper deconvolution or whatever sharpening algorithms) then it will probably surpass the image quality of shifted 60 MP image by a margin, and that would defeat the purpose of technical cameras.

A lens heavier than the 32HR? No thanks, the 32HR is already bulky and the center filter is too huge to accept normal ND grads.

Last night Alpa posted a picture of the 100 MP mounted with the 32HR, but later posted only the sample image of 90HR-SW instead. This isn't looking good for the 32HR if it's not BSI. Maybe Alpa will be able to surprise us.

Yes, the studioshot is excellent and the lack of moire in all the images is remarkable but the detail and rendering of the other images is not that great (airplane image is horrible). As if the upscaled a 60Mp file to match a 100Mp and smoothened out the artifacts. But it sure is because they are initial test shots on a pre production camera or so. The next images will be much better :-)

Hi,

I would assume that MFD also has cover glass. Sony uses around 2 mm, I don't know about the thickness used on MFD. Very clearly, the cover glass needs to be taken into account when designing a lens, espcially if that lens works with large beam angles.

Best regards

Phase One had exclusiveness for the 60MP Dalsa sensor (originally in the P65+) for a few years, so it may be some similar deal here. That would be great for Phase One, and it's more likely this deal to happen for a 54x41mm sensor than a 44x33mm as the former don't have the same mass market potential so Sony doesn't lose as much letting Phase One have exclusivity.

For the users it would be an unfortunate monopoly situation though of course.

Considering it being a joint Phase One + Sony design I think its mostly market speak. Phase One have surely provided input as their cameras have been the target system, but how much can they really affect the design? Probably not so much...

Sounds great. Indeed Phase One has historically been best with a margin at using CCD chips. I think CMOS evens it out a bit as it more about the sensor and less about the surrounding electronics in that case.

Wayne, Theodoros,

From here (https://luminous-landscape.com/100-fxxing-megapixels-phase-one-xf-camera-reaches-100-mp-early-hands-one-report/):

If one carefully reads this statement (from P1's site),....

"Phase One and Sony have been development partners for years, the 50MP sensor being the first milestone of our cooperation, now found in the XF IQ3 50MP. Creating the full frame sibling to the 50MP CMOS system has been a top priority of Phase One for years. Phase One sensor experts have been working hard to optimize the complete use of the 100MP sensor for the worlds most demanding photographers."

....he may find that there is no safe conclusion that P1 was involved in the development of the sensor... As we all know, Hasselblad was first to implement the 50mp Sony Cmos sensor in production... IMO, the (carefully written) above statement, says that P1 was working close with Sony as to develop the ...P1 back, not the sensor!

EDIT: Additionally, I don't think that Sony would "risk" their relationship with other makers and make a sensor "biased" to one maker... Other than that meaning that the sensor would be of very limited production as to be profitable, it also means that they would appear "biased" to competition and this could harm future profitability... IMO, P1 (which is known to be very good marketeers) is trying to take advantage out of the fact that they are "first" in the market with a FF Cmos sensor... (The same everyone would do if they where first).

Don't know if it matters for any other reason than prestige. Sony is not exactly bad at making sensors. It would be interesting if P1 have affected the CFA design to bring that "MFD color" but I doubt it.

Actually I think Canon makes better balanced CFAs than Sony (easier to design neutral profiles especially in the blue range), but they're still far from the mess my Kodak sensor color is. But the real magic is in the profile in any case...

Hopefully it only means that they posted the 90HR-SW because it's even more impressive considering sharpness and image circle.

The 32HR is the one lens to test now though with this back, I'm extremely curious on the result. I have no idea how it will perform. I would not be surprised if it's a huge disappointment, but the opposite would not be surprising either. Someone's gotta test this soon! I can't wait  :)

Hi PPI is coming. On mobiles and tables 400 ppi is not uncommon, and on monitors 200 ppi exists and it will surely become ~400ppi within some years. It doesn't make sense that pixels should be visible to the eye. We'll want the sharpness on screen be as good as in a high quality printed book.

If we want to be negative the biggest threat is that 135 is becoming too good. It's similar to when MFD took over large format film. The break point was 39 megapixels with P45+, many thought LF film was still better, but the 39 megapixels was close enough, more practical and fulfilled all reasonable printing needs. But I think MFD can exist as a niche, having the best stuff even if it's meaningless in any quality aspect still has some nice prestige too it.

I wouldn't buy the new 100MP back at half the current price. Just doesn't make business sense for me. I'm sure there are photographers that need this kit and well done to them.

Hi Peter,

There are a few reasons for that, explanations but not excuses.
1. The denser sampling will gradually have more difficulty resolving detail due to residual lens aberrations. No lens is perfect, and this is part of what you see, more clearly/accurately (and enlarged!). It shows as a loss of micro-contrast at best, or blur if it gets worse (e.g. in corners or near the edge of the image circle).
2. Depending on the aperture, there will be a mix of defocus and diffraction. The plane of best focus is a rather thin zone. There are restoration tools available that can improve that in postprocessing.
3. Improper sharpening. I don't want to sound like a broken record, but people really need to wake up and start using better tools for Capture sharpening. There is also no real excuse for the halos that the images show around edges, only the explanation that the wrong method and settings were used.

There may also be an effect of the Raw converter that was used, I haven't checked the EXIF data of those files yet, but e.g. Capture One Pro is able to extract higher resolution from a Raw file than e.g. Lightroom/ACR. Additionally, if there are automatic lens corrections applied, then resolution can suffer. Resampling always loses some signal strength and usually adds some artifacts. The negative effects of resampling can be minimal if proper algorithms are used.

And finally there is a psychological effect when looking at such (much more) magniified detail on low resolution displays. This all assumes that shooting technique was optimal to begin with, because subject movement, and camera shake, will show.

Having said that, there can be better quality output than some of the examples shown, so take these samples as indicative, but not as an ultimate demonstration of what is possible.

Cheers,
Bart

It seems to me that we are gaining more resolution at the expense of other (more) important aspects. 

Personally, I don't get it. 

I have been comparing the quality of the blacks from my P45+ files to my fiancées IQ260 files and feel that I may want a more modern solution, especially with my recent venture into still life and beverage (most of which are very dark images). 

However, this super high resolution backs just have so many problems associated with them. 

Sure, you get bigger files, but you have to worry about camera shake, lens cast, cross talk, micro lens shading, diffraction, circles of confusion that are not small enough, etc., etc. 

I feel like there is a large majority of not so educated shooters screaming "more resolution!" that drowns out the rest. 

Last time I checked, you only need 12 mega-pixels or so for a full spread.  100 mega-pixels sound great, but at what expense?

Hi Joe,

Well, there's an opportunity for the software industry to help the less educated users in getting better results, and even the educated users can benefit from more intelligent and better quality tools.

There are many types of photography and some do benefit from these kinds of resolutions. Even when technique is lacking, more dense sampling can also help to get better modest size images.

It seems to me that we are gaining more resolution at the expense of other (more) important aspects. 

Personally, I don't get it. 

I have been comparing the quality of the blacks from my P45+ files to my fiancées IQ260 files and feel that I may want a more modern solution, especially with my recent venture into still life and beverage (most of which are very dark images). 

However, this super high resolution backs just have so many problems associated with them. 

Sure, you get bigger files, but you have to worry about camera shake, lens cast, cross talk, micro lens shading, diffraction, circles of confusion that are not small enough, etc., etc.

Exactly, it is a great camera but if i would not had upgraded my H3d-39 and my 1DSmk2 (maybe bought a crop canon for the high iso) until now i would have saved myself some dollas and still had been able to shoot all i shot with my newer fancier cameras at much lower investment cost :-)
Indeed, 12 to 20Mp seems to be enough for about all commercial use :-)
If i had only knew that some years ago :-)

....he may find that there is no safe conclusion that P1 was involved in the development of the sensor... As we all know, Hasselblad was first to implement the 50mp Sony Cmos sensor in production...

Phase One shipped its 50mp CMOS solution months before Hasselblad did.

Maybe you're mis-remembering because Hasselblad did a hurried announcement-of-an-announcement the day before Phase One did after they heard Phase One was about to announce theirs?

Phase One was first to ship the 50mp CMOS. First to ship 60mp. First (and still only) to ship 80mp. First to ship 100mp.

The 32HR is the one lens to test now though with this back, I'm extremely curious on the result. I have no idea how it will perform. I would not be surprised if it's a huge disappointment, but the opposite would not be surprising either. Someone's gotta test this soon! I can't wait  :)

We're on it. Just as soon as our demo units arrive! They are en route at the moment; we are tracking them eagerly!

When you the test with the HR 32mm, can you also capture the same exact image with an IQ260 or IQ360. 

I am curious to know how the color saturation will differ with movements, considering the smaller pixels.

Maybe I should have said a majority of "non-commercial shooters," because any commercial shooter I talk to, regardless, never says, "man if only I could more than double my resolution."  At least not today with what we currently have. 

My P45+ produces a file big enough for any kind of commercial use.  The only problem I have with it as of late is that the deep blacks are not up to par with current sensors. 

Given the choice, I'd rather have a hassle free 40 or 50 mega-pixel full framed modern back then a 100 mega-pixel back with a host of additional issues due to smaller pixels.

Like it or not, the world has changed dramatically. Investing $50K in a camera that does not shoot 6 or 8K footage is not a wise venture, IMO. Unless you have the specific purpose that you are 100% sure will see out the value of the investment. Coming from a high end market in London I do not think that is wise unless you are a hire company.

An increasingly large chunk of high end stills advertising is now a lifted from RED and Alexa footage.

Vloggers and Youtubers are gaining more gravitas than the staple old school print media brands.

What is left in any sort of capacity that someone can make a decent living from is editorial and if you think that these budgets allow or even need a $50K 100MP investment you are deluded or have a rich family.

Yep, but IR filter is almost certainly different so the response is not exactly the same even if the CFA would be identical.

It should be noted that even if CFA is quite different normal low saturation colors will look sort of right anyway, to really see if there's a match you need to test high saturation colors.

All modern cameras today have quite similar CFAs. I've tested a fair bit of cameras and only my own Kodak based H4D-50 was substantially different within the "normal" range, as Kodak has built in quite some subjectivity into the CFAs itself, while all modern cameras are more designed to make objective realistic colors. Regardless you can still make hugely different results depending on profile design, just compare Leaf and Phase One color, despite the same sensor they have quite different color. Leaf ICC profiles can't be used with other cameras as Leaf has it's own processing pipeline with its own way to format their ICC profiles, nowadays builtin to Capture One. Otherwise you could switch between Phase One and Leaf color easily, but due to the different software handling of color you can't which is a good thing for Phase One so the products are more clearly differentiated.

P1 profile = "PhaseOneIQ3100MP-Flat Art Reproduction - Flash.icm" looks decent colorwise with A7R2 raws (rename it to smth like "SonyA7RM2-p1iq3100mp.icm" to use with A7R2) and linear curve in C1

What needs to be kept in mind is that there are many different marketplaces for a 100MP camera beside commercial photographers. Some of these were mentioned in our preview article and include the military, industrial, aerial mapping, museum/conservation and scientific communities.

Let's also not forget China, which within the past few years has become a huge market for high-end medium format derived from all of the above. It's a market that is mostly invisible to us in the west, but is most assuredly no invisible to equipment makers.

And of course, not to be forgotten (because it is likely one of the largest constituencies), are wealthy amateurs. About five years ago I saw several estimates that seemed to agree that the total worldwide market for high-end digital backs was about 7,000 units. My guess is that it's not all that much different today. How the mix of markets breaks down is anyone's guess though.

I will say that when one runs high-end travel / photography workshops (the way we do) and sees the number of serious and often talented amateurs shooting with $40-$80K MF systems, I would not be surprised if as many as half the world market for high-end MF is to affluent individuals. These are the same people who buy top-end cars, boats and homes. People for whom purchasing a $50K camera system like the XF100MP requires little more thought then whether they should upgrade to this year's BMW 750, or wait another 6 months to see the latest models for 2017.

In any business, it's important to perceive the totality of a market, not just to see it through the filter of one's own needs, abilities and experience.

Insofar as your last statement about editorial work, yes I would agree.  That market is shot. 

But in my main market of architecture and interiors, it is very much revolves around stills.  Not sure how that will change, but who really knows. 

Your comments about the Internet and the world changing does not directly relate to the "death" of stills.  Yes, it gives more options for videos to be seen, but it also gives more options for stills to be seen. 

However, I do contest that I think about BC's comments a couple of months ago regarding motion many times, that at this moment those who can produce both are getting the higher paying work (from where he is positioned). 

However, I do wish there would be video capabilities (no sound would be fine) to this back to at least enable the production of cinemagraphs.

If we want to be negative the biggest threat is that 135 is becoming too good. It's similar to when MFD took over large format film. The break point was 39 megapixels with P45+, many thought LF film was still better, but the 39 megapixels was close enough, more practical and fulfilled all reasonable printing needs. But I think MFD can exist as a niche, having the best stuff even if it's meaningless in any quality aspect still has some nice prestige too it.

This was my indirect point - 135 has taken over and 36-40MP covers most things. Prestige is a marketed ideal that we dinosaurs have been spoon fed on. The kids don't really care so much about it and they are the ones booking photographers now.

Hi Joe,

Not that I want to create awareness of another problem you may or may not (sub)consciously suffer from (depends on subject and shooting settings), but higher resolution also prevents many aliasing issues and produces more accurate colors, especially in the shadow regions.

LOL, when I wrote that I was wondering if you would point out moire and aliasing issues with lower res backs. 

However, I can not see better color being a product of higher resolution, maybe higher quality pixels that just happen to be smaller? 

Maybe though, I am getting ahead of myself here since no tests have been completed yet.

At pixel level, a bayer filter image will always look bad, even with diffraction and defocus around, it would look better with real color sampling. I've downloaded the raw file and after removing the horrible processing it had applied I saw a nice image and was suprised that the schneider 80 2.8 was doing "good".

If you're correct on that , it makes a worldwide market of $350,000,000,  retail - and that's assuming they're all running IQ3-101's ( let's not forget the extra megapixel!). In a word: dismal.

Your other point, regarding the affluent Chinese is perhaps more relevant in the short term and there, 7,000 units could easily be a gross underestimation - but equally that depends on how 'flash' your typical Far Eastern buyer views swanning it with an IQ-100 round his neck. My guess is that by the time the next OLED iPhone comes out - not so much.

Nevertheless, kudos to Sony (and Phase) for producing what's no doubt a landmark camera.

If you can't afford the new back, do not need it, do not want it, if it rained the morning of the announcement, who the fudge cares! This has nothing to do with the back and the way it performs and what it can do. The former might be important to the manufacturer and dealers (a few less sales) but it's their business.

Focus people, focus...

I asked a british dealer about the ratio enthusiast vs pro photographers, and they've seen a sharp increase of enthusiast photographers in recent years. In Europe it's not only the highest end products from Phase One that gets all the attention though, the CFV-50c has been very popular for example much thanks to its pricing.

The preowned/second hand market is great too, so those interested in playing around with MFD does not need to spend that much, it's a bit sad that the latest gear gets almost all attention.

If you care about more than resolving power and DR, you can find much joy in using MFD. The reason I use MFD is to be able to shoot in "large format style" (using a Linhof Techno) without having to mess with film. High image quality is only one aspect of that, movements and the slow pace is an intergral part of the photographic process.

If the trend continues and MFD end up being about resolving power only, and movements you fix with focus stacking and perspective correction in post I might just start shooting film in the end :). My purpose with photography is trying to make art, and to make art it actually does matter to me how much of the photographic process that is a craft in the field and how much is post-processing at the computer.

When at large format film, I'd like to say that it very quickly would become more expensive than the MFD gear I have. Shooting large format film has some pretty high running costs.

No, it's due to the denser sampling with a Bayer CFA. In the lower exposure regions, the shot noise plus read noise constitute a random brightness sample in one color band per pixel position. That means that the more random an average sample is, the less accurate the demosaicing will be, and the less accurate the resulting color. This is, amongst others, a reason why deep shadows gain a magenta cast (there is a relative under sampling of Red and Blue noisy samples, but they get interpolated to fill in the missing pixel positions). Larger Red and Blue blotches are the result. A higher resolution sensor offers more of those random samples, and they are like all larger sampling quantities getting closer to the real mean value for those locations (larger sample quantities produce smaller standard deviation).

The fact that the individual samples are also less noisy also helps, they enforce eachother.

There is just one problem. Lenses. Several of the Pentax newer 645 lenses are made to cover the 33x44mm format, just. IIRC the 28-45mm zoom is for 33x44mm sensor only. Ironically the older 645 lenses might work nicely although I would not expect them to get the best out of a 100mp sensor. Even the Hasselblad HCD lenses, the 24mm, 28mm and the 30-90mm only work with 1.1x crop or smaller sensors.

The 100mp chip is the same size as the Dalsa 60mp, which is the same chip in the H5D-60, so the Hasselblad lenses are fine - except for the first and last row (Phocus adjusts accordingly).  The P645 lenses will be interesting, the 28-45 works, based on the chatter about adapting it to other platforms.  The 25mm I believe was canceled due to coverage issues, but I still want one.

I'm myself interested in art photography, and indeed film is big there too. But it's not so much the quality, it's the process, being more "real photography", and the also the look. I'd love to shoot film for my own work, but I'm just too lazy, or at least I say so, to be honest I'm probably shooting too little volume to keep up a stable skill to not do beginner's mistakes on important shots.

There's a lot of talk about the 100MP, but the big thing here is surely that it's CMOS and it's full-frame... you know live view, high ISO, long exposure. 100MP is not that much of an upgrade compared to 80MP.

I think 100MP is quite logical amount for this next top of the hill back though... the only drawback I see is that it's probably hurting tech cam wide performance, smaller pixels makes shading and crosstalk more likely to happen, but if we're lucky it will still perform well due to some new pixel design and that would be just awesome.

If I can get a blue sky and air temperature I can tolerate standing in for the 2-3 hour test you will get your wish!

Thank you so much!

3 frames in portrait orientation will be enough - 1 full up - 1 full up full left - 1 full up full right. just at f/11 that will do it - so it could be done in 10-15 minutes ;-)

If it could be possible to download the 3 files and their corresponding LCC files it will be fantastic!

I'm myself interested in art photography, and indeed film is big there too. But it's not so much the quality, it's the process, being more "real photography", and the also the look. I'd love to shoot film for my own work, but I'm just too lazy, or at least I say so, to be honest I'm probably shooting too little volume to keep up a stable skill to not do beginner's mistakes on important shots. Digital is afterall a lot more forgiving...

I've partnered up with a coudple friends who shoot film more often than myself, and it costs me just a few beers at a time!

Hasselblad and Pentax will eventually have one camera or back with this cmos sensor count. The wonderful but slightly out-dated CF glass could have a come back, as they are optimized for this size capture. With Pentax I would buy an CF adapter and if Hasselblad finally releases a CFV back with a revolving sensor, then 2016 will mark my comeback to MF photography after 12 years shooting with APS and 35FF.
But I don't count on Hasselblad to do it. They are too stubborn! (trying to be nice tho them  ;D).

Surely 100mp is nice to have for some (very few) of cases... I do have a feeling though that if one offers this sensor with four pixel binning ability and 25mp as an alternative choice of use, people will find it much more attractive...

This is a good point. Even those photographers that can make good use of 100mp in some instances will have lots of applications where it is too much. A catalogue, for instance, or corporate portraits that are printed small or used for web, to list a couple of examples.

Hi,

Hasselblad used to make multishoot, but according to Doug their lenses are not up to the task, so why even try?

Another way to see it that Hasselblad had a 200 MP product for a long time and that actually worked well under benign conditions.

Best regards
Erik

They still do

H5D Multishot (http://www.hasselblad.com/medium-format/h5d-multi-shot)

And I still have a H5D-200MS (CCD version, not the latest CMOS chipped version). Doug's wrong.  Hassy lenses are just fine with it.

I just rarely use it.  Its not a practical solution for most situations and subjects.

Doug said? ...about Hassy lenses? ...very reliable information indeed... Besides, who told you that to shoot a 200mp file in multishot mode requires a lens capable to cope with a 200mp sensor in single shot? The truth is that the lens still "sees" a 50mp sensor (for each shot) and it is only required to cope with that... A multishot capture of 39mp will smoke out any single shot capture of any resolution...
Besides, Hasselblad not only offers 50ms & 200ms cameras... They also offer them as stand alone backs for people (mainly pros) to use them on their view or tech cameras... They also have a new (very simple to apply) calibration method which should ensure excellent color and tone accuracy for demanding applications, that P1 can't even come close to.... You have to understand that P1 is addressing their products to cases where color accuracy and extreme detail is not required... they are well behind for professional use in art reproduction or demanding still life photography...

Cultural Heritage Imaging (the broader category under which art reproduction falls) is one of the core markets for which Phase One makes solutions. It has a dedicated version of Capture One for just this market (Capture One CH (http://dtdch.com/capture-one-ch/)) with powerful tools and bespoke ICC profiles meticulously created and tested for pure color accuracy for a variety of supported lighting sources, including the new DT Photon Preservation LED Lighting (http://dtdch.com/dt-atom-entry-level-digitizer/#photon) which has a CRI of 98 and more importantly a CQS of 98 and strong spectral flatness.

I'm glad to help anyone make a comparison in quality for art reproduction of our system versus literally any other made. Just shoot me an email to arrange it.

I think Doug was referring to Hassy V mount lenses, not H mount, and indeed some of the old analog lenses are quite soft. If you shoot for look-and-feel rather than resolving power alone the V mount lenses can do fine results. I'd love to see a CFV back with this new sensor, but I'm not sure it will happen. At some point Hassy will have to end their V support...

Multishot is great and it's can be easily demonstrated that it outperforms single shot and avoids most aliasing issues. I'd guess say Sinar's high end color solutions are more accurate than C1 cultural heritage, but what that C1 package has is great ease of use and a speedy workflow. Exceeding its quality will require expert knowledge and great risks of making mistakes, and its probably not meaningful in most cases which Doug's long list of serious users show.

But if you can only afford to use the best to use Phase One's own marketing language, you shouldn't be using Phase One gear for reproduction work. Multishot is better if you can handle the workflow.

I wonder if the Pentax will be at all. This sensor could be hugely more expensive than the smaller version (I don't know that, but it has often been that historically), and maybe it will become difficult to price a camera that works with the Pentax customer base. Say if it needs to cost $20k, then Pentax decides it's too expensive and don't make the camera. They've also made some crop lenses indicating that maybe they have no interest in going full frame.

I downloaded one of the (iso 50) Raw files from the IQ3 100mp and wow. About as perfect and clean a file as I have seen. It is of an outdoor town scene in bad light. Dynamic Range (shadow recovery) is stunning. I removed all of the (lens, noise, you name it, everything off or at zero) corrections and just boosted up exposure and looked at the darker areas and detail just keeps showing up, clean. Color looks really nice, comparable to what I have seen from the 50MP Sony sensor but even smoother and cleaner. Stunning.

Looking forward to seeing more images made using this back.

All that rubbish and complaining about whether anyone can afford it, need it, want it, whether Phase is gonna survive, whether dealers and the marketing dpt. use cheap sales techniques, whether you can achieve the same using much cheaper gear, etc. etc. just have nothing to do with how this back performs. That is just background noise. The back is amazing. The whole IQ series from the start has been impressive. (I own one, IQ160, and although it was expensive I never regretted buying it, still performs great).

Choosing gear is a very personal process and honestly it is getting tiring reading through all the complaints, rants and rubbish and technical stuff instead of more about how the gear works during photography which is the main purpose of such things. If you find serious faults using the gear in the discussion fine, post them in context of the photography but man, some threads in this forum are getting ridiculous. Just helps to drive away the photographers and technicians who actual deal with Medium Format Digital gear.

Well done Phase One (and Sony) for taking the next step.

I don't get the problem with $44K for a DB.  After a couple of years it has enough residual value to make the next step up affordable.

I spend more money on a work vehicle.

In any business, it's important to perceive the totality of a market, not just to see it through the filter of one's own needs, abilities and experience.

Michael

This is the best explanation of this concept, that tend to elude technical oriented minds.  Many times I have say to my CS peers that if physicians were like CS they will insist in giving the patient the medicine the Md needs and not the one the sick one requieres.  Many people have different desires and needs, and it has been a long time since most of the cameras went to professionals. It's could be that this is not the case yet in MF but if we want MF to survive they need the wealthy amateur market. The investment is simply to high.

I think Phase are very smart marketers. Make a Ferrari with world beating specs, and every institution has to get at least  one, and then a roomful or else ... In fact the price doesnt matter.

And as for individual sales, a guy with $500K in assets can afford the Sony as a hobby buy. Why should a hobbyist with more than $5M in assets care about spending the measly $50K of the Phase when that gets him THE BEST? The only customers who are going to think hard about the cost are pro photographers with their own business, and frankly 1) the price is perfectly defendable as a 2-year write-off if you really need the MP, and 2) nobody in his right mind would make a business selling expensive gear only to money-bound pro photographers these days when any genuinely affluent person can just write a check out of petty cash.

I admire Phase, I really do, they are the only ones in the camera industry who understand the post-recession economics. They are going to sell as many of these as Sony can make sensors.

Phase could give the french lessons in luxury marketing.

Time will tell what Hasselblad has up its sleeve, but whatever the case I wouldn't discount the image quality that some of the V series lenses can deliver. Most are pretty fine and chosen carefully some - in particular the 40mm IF CFE, 100mm, 120mm Makro-Planar, and 180mm - are in fact superb, at least on my 60 Mp back. Having a full format CMOS sensor is a game-changer provided one has the glass that will cover it. Yes, resolution is important but there's more to capturing great images than just resolution and perhaps we've reached the point of diminishing returns in that department (not to say that having more data isn't better). I should also note that some of my favorite images - i.e., ones that hang on my wall as large prints - were made with lenses that aren't considered to be the "best" in terms of resolution. As the saying goes, f/8 (or maybe f/5.6 with those tiny 4.5 micron pixels) and be there!

Why would he refer to V-glass, it is not any longer made? If there is a market for a V-back, I am sure Hasselblad will make it. It is not about supporting the V-system, but simply common sense.

I checked out a little bit, Hasselblad has very good and readable MTF data for their H-lenses, like they had for the Zeiss lenses. They seem pretty good. Of course there are sample variations and bad samples.

Just to mention, I checked resolution on my Planar 100/3.5 on film (ADOX) and it was in excess of 200 lp/mm, but probably at very low contrast. Not that it is that impressive, Erwin Putt measured a bunch of 50 mm lenses some years ago and all had around 200 lp/mm but just a few % MTF. But H-lenses are generally better.

Thanks for sharing the results of your tests of the 100/3.5. 200 lp/mm on a 40 x 54mm sensor (or film) leaves little to complain about and certainly beats the pants off similarly resolving lenses on the 24 x 36mm format. Size matters!

At the risk of straying too much further off-topic (at least until Hasselblad jumps into the 100 Mp CMOS market), Hasselblad published an article/propaganda piece back in 2009 comparing the HC 100/2.2 and HC 210/4 with the older V-series 100mm/3.5 and 250mm/5.6 SA (http://static.hasselblad.com/2015/02/the_evolution_of_lenses.pdf (http://static.hasselblad.com/2015/02/the_evolution_of_lenses.pdf)). The two older lenses appear to hold their own against the HC series. And I've read (but not seen the actual data) that the 40mm IF is the sharpest of the V series bunch.

IBIS?     Nope
6x6?     Nope
Video?    hmmm

Several people at Team Phase One have told me quite clearly there will never be a 6x6 back so I guess I will have to rely on others to do that, or to do it myself :)

But the IBIS? Maybe Phase left the IBIS on the drawing table to leave something to upgrade for in 2 years?

Hi,

I presume that you mean focal plane shutter?

It is quite OK that it is a non starter for many, including your self, but it doesn't mean it would not be a great camera for those who can live without a leaf shutter.

That said, FP-shutter cause vibration, the effect is minor compared to the mirror flap of an SLR. An electronic first shutter curtain, that the new back has, can eliminate a large part of the vibration caused by FP shutter.

Foremost, I see the new back as a great advantage for technical camera shooters, as the back can be used as a viewfinder and also for accurate focusing. Technical cameras usually have leaf shutters, albeit some have focal plane shutters, like ALPA FPS.

Best regards
Erik

Yes, I agree with Ken. The image looks very nice. I could be satisfied with such a quality, with little extra (multi-shot would be nice) to wish for. It will be interesting to see how the images that are taken with shifts will hold up, although perspective correction in software is becoming a feasible alternative (depending on required output size).

By doing it in postprocessing, one can shoot with the higher quality center of the lens' image circle, and have less Color Cast and cross-talk to worry about. It is also much easier to get perfect leveling in software, than it is on tripod. Even with a geared head and a high accuracy digital level, there may be a bit of residual rotation due to tolerances in mounting the sensor in the back.

But the IBIS? Maybe Phase left the IBIS on the drawing table to leave something to upgrade for in 2 years? 

My guess is that IBIS is very hard to do with the mass of such a large sensor and the inherent inertia. We already see that Olympus is a bit more successful with their IBIs implementation using a tiny m43 sensor than Sony is with their FF sensor on the A7 series. Another problem might be cooling.

Hi,

I checked a bit on the image, in C9. Pushing 3.08 EV, with sharpening and noise reduction set to zero, I see some colour blotching in grey areas I would that I would not expect. So I checked in  RawDigger and saw that the image is exposed pretty ETTR, with clouds close to clipping.

What I noticed in raw digger is that the file is 16 bits, but only contains 14-bit data. So the image is a 14 bit file.

Saying that, I think the file is pretty good. Realistically it should deliver data at the same level as the A7rII when pixel peeping. I don't know if it does that as I don't have comparable shoots.

Down sampling to A7rII size (to 40%) would of course improve things quite a bit.

Best regards
Erik



Yes, I agree with Ken. The image looks very nice. I could be satisfied with such a quality, with little extra (multi-shot would be nice) to wish for. It will be interesting to see how the images that are taken with shifts will hold up, although perspective correction in software is becoming a feasible alternative (depending on required output size).

By doing it in postprocessing, one can shoot with the higher quality center of the lens' image circle, and have less Color Cast and cross-talk to worry about.

It does sound promising, but it may not necessarily mean much. Wide angular response is a term sensor manufacturers use about how low an angle a sensor can take before crosstalk happens. So there's some action taken in that regard, but they don't compare to anything so we don't know what it means. This could be a BSI sensor afterall although my inital guess is that it's not. They could simply refer to offset microlenses too.

One should know that modern image sensors usually have rather poor angular response and the old CCDs had better angular response than any recent sensor. So if you compare to the typical CMOS you can make a "big" improvement and still be much worse than an old Kodak CCD.

We really need to see those tests which Doug's is making for us as soon as he gets the back :)

Although I dream of a CMOS that can do the SK28XL without issues, if this just reaches Dalsa 6um class on the angular response it's hugely great news. If on the other hand the sensor makes the Rodenstock wides obsolete it's pretty bad news, so the wait for those tests is really tough :)

This back is too expensive for my small production, but if it's new sensor tech it will likely appear in a 44x33mm version and in other cheaper brands so I'm extremely curious how this one performs.

But as the germans say: "Ich kann nicht die nötige Kleingeld sammeln", so I only have an outside interest.

Yes you are right, it's still the 14-bit up-sampled to 16-bit. Even if you use Capture One to convert it into dng first you still see that gaps.

They seem to have introduced a new 16 bit file format, but you need to set the camera to shoot that format to get it. I assume the test images are the old 14-bit-upsampled-to-16-bit format.

.......I could be satisfied with such a quality, with little extra (multi-shot would be nice) to wish for.......


If Hasselblad will be using the the same sensor, they will most certainly offer a multishot version of it... Other than that, my wishes would extend to a back that would (additionally to multishot) feature the following:

-Four pixel binning for 25mp output ability...
-Interchangeable adapting plates so that one can shim it himself properly and use it on whatever camera he wishes to...
-Raw video recording to an external recorder...

That would make MY dream back.... a real "tool"!

That said, it's not only Hasselblad that can make such a back... Sinar is another player in the game that people don't mention and Leica seems to be working very hard as to catch up in pro video technology... OTOH, if a Sinarback with the above wish list is ever to be introduced, it most probably would have an exclusive to them sensor... Can't help to think that an upsized to (MF) FF Leica S-007 sensor would be of 60mp, which IMO would make it even more attractive...

This "exceptional wide angular response" would also strongly increase the used price of the SKs....

I'm myself interested in art photography, and indeed film is big there too. But it's not so much the quality, it's the process, being more "real photography", and the also the look. I'd love to shoot film for my own work, but I'm just too lazy, or at least I say so, to be honest I'm probably shooting too little volume to keep up a stable skill to not do beginner's mistakes on important shots. Digital is afterall a lot more forgiving...

To be honest, by my latest test, I'm less and less lazy. Many labs around me (and I'm country side) invested in new development machines specially suited for film. Those machines can even "chemically" print digital images on reactive paper. The bath are automatically controlled and are clean and filtered. I understand who give up about film. This is the guys who faced hardgore the digital transition (sorry Doug ^^). They started to digitalise thousands and thousands of negatives thus killing any joy in the process. Digital for them is a Deliverance, to say the least.

Today film is maxed and do not suffer WA smearing :) Digital isn't maxed yet but is a super complement. Digital is the new pola. It is a good period for a photographer to "taste" real MF with film at little expense. Take your roll in any labs (at least with modern frontier or equivalent) and you are done. Choose the pics you want digitalized or do it yourself at home with a lightbank and a Merrill sensor stitch. For ppl seeking a pleasure of photography it is ONE way to go, for sure (not the way).

Of course such expensive and top notch items will find a house somewhere on the planet. Michael said the market is 7k Unit but IHMO, in late 2015 and start 2016 it is more 5k units worldwide. Asia market will buy most of the units. Asia is now where USA where in the 80/90's but with modern tech. When they do something it is just huge.

Speaking of film, there are a few comments I want to make about P1's XF camera...
It certainly looks to be a very capable tool of equipment... but P1 has made everything in their power to exclude a major part of the market from buying it...
1. There is no provision for film backs
2. One can't use a multishot back on it.
3. Even older "in family" MFDB owners can't retain their backs and upgrade to the new camera...
4 ....the IQ3-100 back is only usable along with an XF platform...

I've no clue as to why P1 is closing their system, I've only to remind them what the (financial) result was with Hasselblad when they took similar decisions against the markets requirements. I can remember people in forums ADVISING Hasselblad to reconsider their (stupid) decisions ASAP... They didn't listen, they kept insisting that "they know better than the photographers on photographers needs..." (!!!!!)

Well... if in P1 they think the same, I have ONE proposal for them as to test the result...
 Offer an alternative version of the XF camera with all the interface "blocking" of MFDBs removed, compatibility with MS MFDBs and film backs too... (abilities that the H5X already offers)...[/i] Lets then see which will be more successful... Will it be the current version or the "simplified" one? Come on guys... it's a simple marketing "test" that costs nothing... it only may help you to "wake up" before its too late...

As for Hasselblad, one must say they haven't wake up completely yet... Not unless they will resurrect the CF series of backs and offer them "open" to other platforms as they used to do... Especially the MS versions of the backs which they now sell as stand alone backs (but only for H-mount)...

There is no "block".

The XF speaks a different language (aka "intercomponent communication protocol") than legacy Mamiya bodies. Using the Mamiya 645 digital interface spec would have been very limiting given it was developed more than a decade ago.

If Hassy or Sinar want to make a back for the XF they are welcome to. I think Hassy will have no interest as they want to support the M platform. Feel free to talk to your friends at Sinar.

Also I think Phase One innovate and invest a lot. They can't keep old tech while building new. They can eventually restart a "legacy" market and even a scanner based on their backs and relaunch the mamyia 7ii or equivalent :) I know I dream but I smell a little niche market based on this idea.

I'm sure they know their still potential in film but it seems to be hard to predict such market.

Having never shot with a high mp back, I do wonder other than detail, does the high mp back give better gradation or is that entirely down to bit depth?
I would of thought the ability to capture gentle tonal variations is going to make a photograph more beautiful or real rather than being able to count a few more blades of grass.
Is there a difference between 50mp and 100mp in this area?

Hi Eric,

IBIS is not just a sensor, but it is a sensor-assembly (which does not yet exist for this format) that holds the sensor, electronics and acceleration sensors, and lens info/sensors, to even make a first start at stabilizing.

Developing a sensor assembly may be interesting if Phase wants to add multi-shot capabilities, it could serve both goals, but the multi-axis stabilization part is quite something else than shifting the sensor back and forth in half or full photosite pitch increments.

And then there is the software part ...

Cheers,
Bart

Yes, just a few pixels in the Christmas lights are clipped, pretty much ETTR.

I haven't had time to dig much further, but that would be consistent with the Dynamic Range that I found, 13.65 stops (assuming Rawdigger interprets the file data correctly).

In short, given equal composition and similar per pixel performance, yes, it helps a lot since you are increasing your sampling of any given area in the frame with more pixels.

This back will be made in H mount (Hasselblad H1, H2, H4X, H5X) and M mount (Phase One DF+ and Phase One XF) versions.

C mount (Contax 645) and V mount (Hasselblad 500) are not currently planned. But if you would want one I suggest you contact your local dealer. They could always reconsider if there is sufficient demand.

 Too many charts and graphs in photography these days to decide if something is good or not. If you can't hang a number on it people have no idea or confidence in a product.

I suggest you compare sample shots and make test prints, because there's many different opinions about these things. The thing with "better tonality" is one of those effects that's hard to show in any measurements but some experience it, if it's placebo or not I can't really say.

To be considered is that the standard is moved forwards all the time, in all formats. It becomes more and more difficult to see issues in the images, and as such the differences become smaller and smaller. Personally I doubt that you would get a big tonality improvement from an IQ250 to an IQ3 100. In fact I think it would be difficult to tell prints apart on a normal viewing distance.

Higher sampling is good though, you get less aliasing in small details, which can be an advantage in certain shooting conditions.

I'd say that today's hardware is so good across the board that "tonality" is more up to profile design than actual hardware properties.

I was just curious, not enough to start downloading files and making prints. I would hope the new back brings more to the party than resolution, the 50mp cmos looked to be a big step forward for MF.
I can only think of one job I've done in the last two years where resolution has been of any importance, no doubt for others it will be important, the rest of us 16 - 25mp is probably enough.

Resolution is improved and aliasing is reduced at the same time, both allow more accurate tonality and smoother gradients and better microcontrast. The physically larger sensor will allow to use a larger magnification factor on sensor for the same Field of View, compared to a physically smaller sensor, which will then result in a higher MTF, which also gives more solid data (higher S/N ratio) for postprocessing.

I don't really ever get into the deep technical issues, so let me know if my logic is flawed here...

The IQ3 100 and the A7r2 have a similar pixel pitch, 4.51 µ on the Sony and 4.6 µ on the Phase.  Given that, lenses that resolve well enough on the Sony should be fine with the IQ3 100, yeah?

I've been using 'Blad CFi and CFe lenses (and the Canon TS-e's) since I built my Sony rig and have been pretty happy with their sharpness, so I'm guessing I'd be happy with them on the new back, too.  Of course, I'd need to add the focal plane shutter to my Arca.  Hmm... interesting.

Chris,

This would be my take as well, provided the lenses perform well enough at the edges and corners of the larger sensor (which some but not all of these old lenses seem to do). The beautiful and technically excellent images you have posted here speak for themselves.

Do I remember reading somewhere that the 17 and 24mm will cover this sensor still with some movements?  Thus the 17 becomes an 11(ish) with movements and the 24 a 17(ish) with some movements.   (adjusted focal lengths referring to field of view in 35mm terms)

I think someone tested these on the H-Cam?

Really interesting then to have on the view camera.

I think this new achievement is opening a world of opportunity to see new product and some concurrence / price reduction in the months that come.
First maybe someone selling the old gear to buy the 100MP increasing used market on the net that is where second hand from professional, doctor & dentist gear gone in good hands of creative and jung photographer that simply can afford the buy of this MFD gear / back's.
Generally speaking all old gear have characteristics and IQ well beyond what it's possible to achieve with a DSLR (also the newest), so if also Pentax and Hasselblad enter in this run for the big 100 Mp i think some benefit and price reduction (like the one active in this holidays for H5D-50c) will arrive.

To return to the discussion about the new born, I admit to have some doubt about the performance, especially about the noise in low light,  the 4,6 microns are at the level of some apsc dslr and no sony nor others brands perform brilliant in low light / high ISO (well, recently they have improved but after all i use always base ISO if I search the best IQ).

There is no "block".

The XF speaks a different language (aka "intercomponent communication protocol") than legacy Mamiya bodies. Using the Mamiya 645 digital interface spec would have been very limiting given it was developed more than a decade ago.

If Hassy or Sinar want to make a back for the XF they are welcome to. I think Hassy will have no interest as they want to support the M platform. Feel free to talk to your friends at Sinar.

Do you mean that a version that "speaks" the old M protocol is difficult to make? Or is it an intentional decision of P1 not to offer the possibility?
Listen Doug, the most unethical way to avoid saying the truth, is to answer irrelevant on a question... P1 could have the  "intercomponent communication protocol" or the "old M protocol" both included as user choice in the menu... That would allow old P+ users of backs, as well as users of other brand backs to select the "old protocol" if they want to keep their old  back and change to the "newer protocol" if they ever decide to upgrade to an 1Q back... Most of all, it would cost absolutely nothing (but a few KBs of memory) to do so...

As with Hasselblad, most probably they would consider to support the "old protocol" as their MS mode backs wouldn't work with the "newer one" and "my friends" (as you call them - although they are not more friends than you are to me) in Sinar, make an adapter for the "old protocol" for many years now and I don't think they would ever consider the "newer one" unless the user can take advantage of the MS mode of the backs...
By the way... this is great news we've had from you... I mean the information you shared that Hasselblad will offer back their backs for third party platforms! ...great news indeed!

I guess if in P1 they'll decide to "open up" the (great) XF body to the "old protocol" that will be even more great news! ...and if they decide to ever offer a back (I suggest the IQ 160) with multishot ability, it would even be greater news!
I guess you think that the criticism (not only from me) to P1's products or decisions (that you consider as being "perfect") is bashing... but I assure you, its only criticism which aims to help MF grow... After all, all makers must be doing (or have done) something wrong if MF market is shrinking.... isn't it? ...and not supporting film backs is one of this "wrong"...

The 32mm is nice, however the top of the sky gets fairly noisy. 

Since they did not list it, I have to assume this was taken without the CF, so part of that noise may be coming from light fall off correction, as well as for lens cast.  Would that be a good assumption? 

The 43mm looks really bad at the bottom!

Hi,

There are two benefits of smaller pixels and they are that:


On the other hand, there is no real downside with smaller pixels. Also pixel sizes get reduced with newer design technologies. So we had one optimal pixel size for 0.5 micron design rules and another for 0.18 micron design rules.

There are two disadvantages with smaller pixel sizes. The first is a small reduction in dynamic range, the other is that pixel shading effects and risk for crosstalk (contamination of colour between pixels) increase with small pixel sizes. These effects don't really affect SLR type devices but are definitively problematic with technical cameras when used with non retrofocus wide angle lenses.

The present 100 MP sensor gains it's resolution from increase in surface area over the 50 MP sensor. The pixels are not smaller there is just more of them.

Best regards
Erik

I think this new achievement is opening a world of opportunity to see new product and some concurrence / price reduction in the months that come.
First maybe someone selling the old gear to buy the 100MP increasing used market on the net that is where second hand from professional, doctor & dentist gear gone in good hands of creative and jung photographer that simply can afford the buy of this MFD gear / back's.
Generally speaking all old gear have characteristics and IQ well beyond what it's possible to achieve with a DSLR (also the newest), so if also Pentax and Hasselblad enter in this run for the big 100 Mp i think some benefit and price reduction (like the one active in this holidays for H5D-50c) will arrive.

To return to the discussion about the new born, I admit to have some doubt about the performance, especially about the noise in low light,  the 4,6 microns are at the level of some apsc dslr and no sony nor others brands perform brilliant in low light / high ISO (well, recently they have improved but after all i use always base ISO if I search the best IQ).
Dubt about the 16 bit.... it's not clear, and from the doc I have see there is a cloud around it, first SONY doesn't distribute a DATASHEET of the sensor perfrormanche and the schematic block of the multiplexer / ADC....  remember the DALSA and KODAK (now ON Semiconductor) data-sheets (I.E. http://www.onsemi.com/pub_link/Collateral/KAF-40000-D.PDF   for who doesn't even see one in it's life)...

How did you ever end up to this conclusion? The surface area (entrance) of the 100MP sensor pixel is almost 30% reduced if compared to the respective 51mp one...

In your view, what is the maximum amount of shift needed with a 32mm lens for architectural photography?  If the type of structure you are shooting allows for nodal panos, is shooting the 32mm cause too much distortion?

I'm not an architectural photographer, just curious. Thank you.

Post by: torger on January 05, 2016, 04:23:45 pm
It doesn't look too good on the wide angle compatibility. The 32HR has loss of color fidelity with only 10mm shift. The effect is much stronger on the symmetric SK43 of course.

Crosstalk issues are a bit unpredictable as they are orientation and subject specific so it's hard to make a final judgement based on one shot, but my guess is that if this back is better than the IQ250 it's not with a wide margin, still considerably worse than the Dalsa CCDs.

The super-high DR will somewhat compensate the signal loss, but loss of color fidelity is hard for me to swallow, as I think color is at least as important as resolving power. If you want you can see it as a sort of creative vignetting effect and live with it though.

But I guess that Rodenstock needs to start making some new wide angle lenses, because this is the new deal, Sony is probably not going to adapt to tech wides. A little too early to say drastic things but I'm afraid that Rodenstock wides may now be as obsolete as Schneider Digitar wides became with the 6um Dalsa - eg they've become more or less center frame lenses unless you use them with the older sensors (with Digitar it was using Kodak instead of Dalsa, and with Rodenstock its using with Dalsa instead of Sony)

The 32HR can be pushed to almost 15mm +/- on the CCD backs, so would be nice to see more extreme samples.

Is it me or is there some strange vertical blotching in the sky areas of both 32HR images?  The edges are not quite well defined to be called banding, but there is somethings strange going on there.

You can look at the top corner of the building of the first 32HR shot. If you're used to see color fidelity issues you can see that the're something wrong despite the low saturation color. There's residual casts after the LCC has been applied, which is typical crosstalk effect.

You can also see the shifted areas be clearly noisy, and as this is an extremely low noise sensor it means that the LCC algorithm is really pushing it.

You can clearly make images with this combination but it will be "unstable" in some cases it will work out fine, in others you get residual effects, often quite mild which you need to look hard to see like in those two 32HR shots. Sure that will be okay to some, but to me it's not acceptable for a high end system to perform this way. Then I rather use "yesterday's" hardware like an IQ380 on that 32HR...

As we know the Dalsa's are not without issues on the Rodies either, ripple and tiling can show its ugly face sometimes, but my preliminary guess from these jpegs is that this new CMOS will have much larger issues than those. Center frames are probably fine though, so the Phase One "A" system (=an Alpa with no movements) is probably okay.

I guess that our friend Doug will cast some light on the shift performance when he gets his sample of the new back.

I would be surprised if Alpa had shot the 32mm without center filter though.

The whole appeal of the back as a universal solution is pretty much at stake here.

@Jeffery, in the past, using the SK43 and the IQ260, it wasn't uncommon for me to shift up to 15mm.  With the SK35, I could get away with maybe 12.  So the 32mm HR may be a workable solution if it can go to 12 or 13mm.  The problem with architecture, though, was there was never a wider solution that was really workable and I always had to carry the 17 TS-E and a dslr for those occasional superwide shots.

Nodal stitching is a no go for me as I'm already always compositing for dynamic range and having to work rotations into that too is a nightmare for post.

I'm testing the back all day tomorrow alongside my A7r2 with Kevin.  I'll post my results.  Sadly, I have no wide Rodenstocks to try out.

The whole appeal of the back as a universal solution is pretty much at stake here.

I see it as a threat to the whole movement-centric view camera shooting style on the wide end.

I think this will happen: in the XF system the CMOS will become so popular that few new CCDs are sold, meaning that Phase One will not make CCD backs for the IQ4 series. That is these CMOS sensors is what tech cam industry must adapt to.

In the tech cam camp the 100MP and CMOS live view will be so sexy that many will choose to ignore the cast issues and thus the CMOS will sell well to tech cams too. Over time people will discover issues and "solve" them by shifting less, and start doing perspective corrections in post and such things. That is the tech cams become more like P1's A system, just a very sharp center frame snapper.

To get from here either a new generation tech lens friendly CMOS need to appear, which unfortunately I think is unlikely to happen in near time, or Rodenstock needs to make a set of new wide angle lenses which are stronger retrofocus. Schneider as we know has already left. There's also the Cambo Actar initative which we may see more of but this time for medium format size, that is that a tech cam manufacturer source in their own lenses just to get a working system.

The most likely scenario I think is a new set of wides, but how long will it take? It can be a few years, a period when tech cams may become known for their many issues on the wide end and lose popularity.

If I were Alpa, Cambo, Linhof, Arca-Swiss or Silvestri now I would be pretty disappointed because it will hurt their business that the highest end back will have quite serious issues with the wide angle lenses for their systems.

If I had an 60/80MP Dalsa now with my tech cam I would be really really really careful before upgrading to this. Note that I was also quite negative about the IQ250 wide performance and we could see that many still thought it was good enough for their needs... so we'll see how this one lands over time. As a large format shooting style fan I'm now certainly a bit worried about the situation though.

Hi Peter and Jsiva,

The blotchy look you are seeing in the extreme shift, seems to have been carried over from the 50MP chip.  When I tested the 50MP on extreme shifts, with the 28mm and 40mm and 32mm (loaner), I saw this same issue.  It only manifested in solids, like this blue sky.  Made worse in B &W.

Opened a case with my dealer and Phase One on the issue back in March 2015 and nothing ever did come from it, however Phase did admit to seeing the effect and agreed it was not my lens or something in post I did to cause it.

I found that Topaz denoise can help smooth this out, as it has an actual de-banding selection. 

Interesting to see this problem again.  Note, this is not to be confused with microlens ripple which makes a much more solid stripping and is most times removed by the LCC.  In my work the LCC did not effect this blotchy banding effect.

Edit:   The 100MP does seem to handle the color cast issues on shift much better, if the smaller shot from the Alpa site is before the LCC was processed.  With the small 50MP chip all of the left side would have been visibly red, and you don't see that in the Alpa shot.  So good news there.

Post by: torger on January 05, 2016, 05:29:38 pm
A raw LCC shot of a shifted lens is telling if analyzed. The bayer array can be seen as groups of 2x2 pixels of one red, one blue and two green. In a shot with "normal" color casts green1 and green2 in each of those 2x2 groups should not differ much as they should locally see the same color. If the values start differing say more than 5% in the shifted areas this means that there's crosstalk, one green gets leaks from mostly red pixels and the other mostly from blue. This can't be cancelled out by a normal LCC algorithm and that's why you see the brown dead color in the shifted area of the SK43. The effect on the 32HR is much smaller but I think it's there unless there's some strange flare or post-processing effect.

You can still make images when this happens but you can get some hard-to-predict effects on your hands.

Also note that this sensor just like the IQ250 sensor probably have offset microlenses which assume that the center of the lens is in the center of the sensor. This means that it works best for center frames, when it's shifted large amounts the offset microlenses can get the reverse effect and hurt the performance rather than improving it. This means that when you make shift tests you should not just test say 0mm and then 20mm and interpolate the results inbetween as 20mm could be drastically worse than 15mm in the same imaged area. Better to test in say 5mm intervals.

Another good "sanity check" test is to make one shot with the back in normal orientation, and then make the exact same shot with the back upside down in a scene with stable light. If the LCC algorithm is unable after white balancing to present the same uniform color of both these shots then there's some substantial crosstalk going on. More saturated colors make it easier to detect.

If you have really severe crosstalk you can see "mazing" at pixel peep, but C1's demosaicer is really robust against this issue so then you really need huge amounts (like 30+ percent if I remember correctly)

The "danger" with these effects are that they can be quite subtle and if you don't know what to look for you may miss them only to discover it later on when you've already bought the stuff.

I'd also look for wavy microlens ripple effects, there was some of that on the IQ250 which was hard for the LCC algorithm to cancel out.

Also don't forget that Rodenstock lenses are more retrofocus the wider they are. That is the 32mm is more retrofocus than the 40mm. They've had some design target of maximum light angle and to meet that they've used increasingly complex lens designs (or smaller image circles) on shorter focal lengths. I don't know the exact differences but the point is that if you get great results of a 23mm center frame you can still have issues with a 10mm shifted 40mm. The popular SK60XL can also show problems with larger shifts as it's symmetric.

Thank you Chris. I appreciate you sharing this info. When I get my tech cam my first lens will be an HR 40. (Mainly for landscape with people and without)  It’s great to learn something new.  Not sure when I will apply the knowledge, but it’s good to have it in my mental tool kit.

The 32HR can be pushed to almost 15mm +/- on the CCD backs, so would be nice to see more extreme samples.

It may... but it may also work the other way around (as it does to some extend now...). Meaning that the "clever" guys will buy the old lenses for cheap, add even cheaper the old 33, 39 & 50mp CCD sensor backs... and invest the difference on the cameras just producing jaw dropping images with "the good old fashion way" of focusing...

Heck... I bet the FUJI GX-680 will be the best camera & lenses to use with this back... but again, one has to still find a solution for a "true" WA then.... Wait a minute... where is that old 6x8 film back?  ;)

Thanks Paul.  I think you are right regarding similarities with the 50MP chip. 

Yes, the smaller inset image appears to be quite good, as in no visible magenta/red.  Flip side though is noise and still strong light loss in the shifted part of the image post LCC.

When looking at the 32mm sample from Alpa, it gave me the same feeling that I would get when looking at a P45+ file with my SK 35mm shifted with no CF.  It is not pretty, but using a CF cleans up the file very nicely. 

Considering the Rodie 32mm has 3 stops of light fall off (compared to the 3.5 stops with the SK 35mm), I have to assume (and hope) that image was captured without a CF.  This could bode very well if this is the case; the file could be very clean with the CF used. 

This back could work very nice with a tech camera if so. 

I would say that with a lens as wide as the 32mm on a full frame MFDB, I would only shift 6/8 mm for most interiors and many exteriors.  Yes, there would be exceptions, like in lower Manhattan where the streets are very thin and the interiors very small, but overall it would be produce an acceptable quality, probably better that any 35mm solution.

Anyway, the Rodie HR 40mm and Rodie 55mm is where I am most interested.  Those are my sweet spots for interiors. 

I am really curious to see how the resolving power (or lack thereof) of the Rodie 55mm holds up with such small pixels.  With my P45+, it is very sharp until about 15/18 mm of shift.

With my Credo 60, the Rodie 55mm is pretty average when shifted beyond 10mm so I expect with this back–particularly if these early test samples are anything to go by–it'd very quickly show it's age off centre, both with regards to sharpness dropoff, but also luminance falloff. I wish Rodenstock would design a new 55mm lens upto task of the modern, 80+ mpx sensors.

I think the 40mm HR-W is a stunning lens. It behaves well and it is not too big, it is easy to filter (no need for a CF) and at least with my IQ160 it allows a large range of movements. I use it basically up to the 15mm limit (L-R) on my RM3Di. If I have some rise/fall dialed in along with the 15mm shift I might hit the limit of the image circle in the very corners but the image quality is superb almost up to the very sharp edge of the disc. The 70mm HR-W allows even more movements and it requires even less extreme L.C.C.'s. Very very mild ones in fact.

My bet is that these two lenses are gonna work beautifully with the IQ3 100MP back. Looking forward to the test results.

I would be surprised if Alpa has shot the 32HR without CF, but of course we don't know. If they have noise will clean up somewhat, but the non-uniformity color issues will not. I've learnt though that uniform color is to many a lot less important than corner pixel-peep sharpness so it will be very exciting to see how much issues people are willing to accept.

I forgot to mention one more sanity check test that's really useful --- sensors may perform very differently in portrait vs landscape orientation, depending on how wiring is oriented on the chip. That is you can have lots of crosstalk in one orientation and much less in the other.

So when testing shift performance you should test in both portrait and landscape orientations.

Team,

I have been playing with the city raw sample image in C1 Pro 9.02. I'd be curious to hear what settings you guys are using for the IQ3 100 files?

Personally, here is what I did:
- ICC profile: IQ3 100mp Outdoor daylight
- Curve: High contrast
- WB: 7750, Tint: 24
- exposure: +0.3
- Contrast: 15
- Brightness: 20
- Saturation: 5
- Hilight recovery: 60
- Shadow: 30
- Clarity: 30
- Structure: 5
- Sharpening: amount 400, Radius 0.3, Threshold: 0.8

I did also apply verticals correction and a few layers to selectively darken the sky.

It looks much better to me than the initially provided settings. What did you guys do if I may ask?

Thanks.

Cheers,
Bernard

Hi,

Hasselblad used to make multishoot, but according to Doug their lenses are not up to the task, so why even try?

Another way to see it that Hasselblad had a 200 MP product for a long time and that actually worked well under benign conditions.

Best regards
Erik
Hasselblad still does multi-shoot, and multi-shoot does not stress the lens any more than a single shoot.
So if the lenses are good for a 50mpixel capture, they will be for the 200mpixel capture of the H5D-200c.

You insist that the product is not for sale when it is, based on the  50mpixel cmos sensor.
http://www.bhphotovideo.com/c/product/1078381-REG/hasselblad_3013708_h5d_200c_ms_digital_camera.html
The new machine performs far better than the old one.
Phase one has a very good  camera, and as always fantastic  software and backs. There is no longer a need to a need for this kind of stuff.

Best regards,

Hi,

You take make posting the wrong way. Doug said that the Hasselblad lenses were not good enough for the new sensor. So I made the point that they worked fine with multishot, which yields 200 M. But you are dead wrong that if a lens is good enough for 50 MP it will also be good enough for 200 MP multishot. The other way around is quite true.

Just consider this, you cannot resolve something by multishoot that is not projected by the lens.

Chris Barrett and I will be shooting tomorrow with the ALPA system and numerous lenses.  I just did some tests shots with the 23mm Schneider and they are pretty damn nice.  It's a problem putting RAWs up on the Luminous-Landscape site because of the size.  Our download file system has a max of 100MB and the RAWs exceed that.  Our IT guys are looking into seeing if it is possible.  Chris and I will report back plus we'll have a more in depth report in the weeks to come.  If you can make it to Indianapolis and I'm around you're welcome to give it a try with me.

Each raw is around 100MB. Sharing 10 raws to 20 people, or 100 raws to 2 people, or 8 6-shot stitch 16-bit TIFFs to one person via dropbox will hit Dropbox's bandwidth limit (https://www.dropbox.com/en/help/4204).

No... it's not (the other way around)...

You don't count the (physical) sampling... (meaning that you think of it as if it was a single shot)... With multishot you practically quadrable the Niquist limit... (because you are shooting on 4 image areas that are in different position to each other...) For example, if one is using a Sinarback 54H in 16X mode and uses the Zeiss Contax 120mm Apo micro with it, the result (if one masters the process well) should be the same as if shooting (a single shot) on a 10x7,5cm (aprox) image area, but with 9μm pixels of true color (88mp in total) and has used a 240mm lens that is of the same LPM resolution & contrast as the 120mm has (but with an image circle as to cover the whole 10x7.5cm image area)....

I remember others asking the same... I believe there will be no answer on this other than the usual... (POA kind...). Now, why do I have the impression that the sensor (and hence the back) costs less than an IQ-160 to make but the "pricing according to resolution" policy of P1 (and others to be fair) won't change?

Hi,

I am not a Hasselblad Multishot expert, but my understanding is that for 200 MP you do 16 exposures while shifting the sensor a half pixel. Now shifting the sensor a half pixel between exposures gives you for point samplings per pixel. So, what happen is that you split the pixel in four subpixels, each half the size of the original pixel. You don't loose full well capacity as you shoot four different exposures.

But, what happens is that you effectively reduced pixel size. You actually gain a lot, because you also take 16 exposures and can eliminate much of the Bayer interpolation, definitively a good thing.

Yes, you double Nyquist limit, but it is by virtue of emulating half the pixel size. So, to deliver 200 MP, your lens actually need to resolve those 200 megapixels, it is as simple as that, and if they do that, they will work just fine with an 100 MP back.

Some more user-contributed tech cam samples over at getdpi. Large shifts on the 32HR is certainly a no-go due to residual color cast. But due to the offset microlenses it's not possible to state an exact limit without stepping, eg try 5, 7, 10, 12, 15, 20mm. The limit may also be different in portrait and landscape orientation.

If you have a IQ260 now with your 32HR upgrading to a IQ3 100 will for sure strongly reduce the shift range. Center frames is probably without any significant issue as the offset microlenses will do their job optimally when the lens center matches sensor center.

There were those that kept their SK35 after upgrading to 80MP Dalsa they just stopped shifting or shifted with very small amounts, just like SK28 actually despite its huge problems with Dalsa is used by some for center frame and like 5mm shifted shots. How much shift is actually needed for the 32HR to keep its relevance as a 645-fullframe architecture lens? I guess Chris or any other experienced architecture photographer can give some good insights on that.

My own guess is that 12mm in landscape orientation would be a suitable target for some sort of lowest acceptable minimum, that is what I would want for my landscape photography at this focal length. Unfortunately the indications so far is that we need to settle with less.

If the 32HR had a bigger imagecircle I would for sure use it - The amount of shift I can get on my iQ160 is just sufficient - the amount I can get on a 80mp back without banding, tilling and destroyed colours is not sufficient for my use.... and yes I have only Rodenstocks below 72mm.

Hi Anders,

But less shift is required because of the wider angle of view on the IQ3 100MP, isn't it?

It depends on how you see it. The way I see it a lens with a certain sensor size provides a certain field of view, and for that combination to be used to its fullest in terms of image composition it must be able to make certain amount of shifts relative to the sensor size so the "horizon" can be placed low/high enough => larger sensor larger shift, but you can also use longer focal lengths. The 32mm is very wide, I'd satisfy with 40mm as the widest for my landscape, but architecture photographers needs really wide stuff.

If you instead just see the image circle as a place to stitch any area you want it is like you say.

If you have a lens with small shift range in relation to the compositions you want to make you can feel limited when you use it. As a comparison you can look at the relative shift range you get with a 5Ds and a TS-E 17II or 24II, it's huge relative range which the 645 tech cams aren't close to. The 645 tech cams have killer resolving power of course, but if shift range becomes very limited that could hurt their relevance as tools for architecture photographers.

I'm seeing Dalsa becoming the new Kodak behind Sony, and Rodenstock wides the new Schneider Digitar wides behind -- nothing -- and that's the worrying part.

Got it, and I agree mostly (although I do not like straight captures with such wide angles of view). I was thinking more of a comparison with a physically smaller sensor, like the IQ250 has. In that case one would not need as much shift due to the larger area of the image circle that's used by a physically larger sensor.

Yes I understand, but there are other possibilities than using optics that create issues that cannot be accommodated for. A simple stitch of two or three images can sometimes solve a lot. It allows to use the center of the image circle (is better quality), perhaps use longer focal length (is usually better image quality), and the stitching software can allow to use a projection method that preserves certain straight lines/edges, yet compress the extreme stretching to a perceptually more normal proportion. Leveling and squaring surfaces is also much easier and more accurate than possible with a limited preview screen size, and saves time on location (less variation in outside light conditions).

So maybe a slightly different workflow can also be an alternative.

I thought that's what you (and others) presume it happens, but it's not... You don't "split a pixel in four"... what happens instead, is that you create a new (real - true color) pixel of 9μm that has another 8 around it... Out of these 8 pixels, the upper, lower and side four are also new pixels (the five of them forming a cross), while the corner four are identical to the ones that would exist if the same back was shot at 4x mode, (but moved when mapping the final 16x image a row or a column away from what would be their neighboring column or row if shot at 4x mode). Don't forget that each one of the 9 positions of pixels in the above example is a result of four shots each, resulting in a true color one... None of the resulting pixels of the final file uses existing (position or color) information used by a neighboring pixel...

EDIT: I had to edit this, as in the first place I've put things the other way around than there is (by mistake). In the first post I had the pixels that are identical to the ones that would exist if the back was shot in 4X mode where the ones of the 16X mode are created and vice versa.

Whilst it is a viable method, it comes with it's own set of difficulties as compositing of exposures is also common practice.  ie - time on the computer goes up!

I stitch a lot, direct stitch where you are shifting the lens or back, here you can, somehow, easily combined different frames of the images so you can place people or not for instance....but if you start stitching around the nodal point, without shifting, as suggested here, you are asking for all kind of troubles with lines not lining perfect up and so on. If you have all the time in the world you can maybe make it work, but in a commercial workflow - that would be a challenge.

Yes, also because it is faster to use an extreme wide angle lens rather than a longer lens and stitch. Both can yield the same effective angle of view / coverage but one adds several steps in the workflow. Also in instances where there are elements moving the frame one shot capture is preferred for obvious reasons.

I am hired to shoot dozens and dozens architecture projects each year. Most involve interiors with available light. The jobs do not pay very well (quite a few people get paid even less than me in the local market and those drive the price down) and to be profitable one must be very fast and efficient and of course produce really good images consistently. Partly to be able to have a fast turnaround and also because sometimes access to projects is very time limited.

I mainly use my Canon cameras due to them producing good color in mixed and low light situations and also due to the high quality wide angle lenses available. For interior shots the 14mm L II lives on my 5D3. The new Canon DSLRs also require basically no dust spotting in post (the Nikons and Sony, and of course MFDBs still require a good bit of it). Might be a stupid thing but saves a ton of time although today's software has improved on this tremendously. The dynamic range is good enough for 99% of the time. I do wish for better in a few instances though. (Hence why the D810 and the A7R/II are so popular for Arch. photos).

I have used my tech camera and IQ160 back for some specific jobs and of course results have been stellar.

But generally a DSLR system is preferred due to the faster workflow, lens selection and the integrated body.

I would love to use a XF and a IQ150 for Architecture but one key element is missing, an ultra wide angle lens. Yes that can be solved (substituting the XF) with a ALPA FPS (or Hartblei or Arca Body and an FPS plus adapters) and a Canon 24mm TS-E II (which I own) or even the 17mm, but the cost is prohibitive and you loose the convenience and speed of working with a DSLR.

A Leica S (007) is a good alternative though. Same with an H5D. Both systems have a good 24mm lens available. The 645Z would be a great choice if it had an extreme wide angle lens available.

Of course image quality wise the 100MP IQ back is most likely above all. Would be awesome if Phase made a 24mm lens for the XF system. That would round out the system nicely. The new 35mm seems impressive.

Again all my comments are for Architecture and Interiors photography.

It would be a pretty simple engineering challenge to design a motorized head (already exists) so you just press a button to shoot all frames, and get a preview image in the tethered computer, choose perspective and crop, and voila an auto-stitched virtual raw that you then process in your favourite raw converter like any other raw. As far as I know it doesn't exist software to make the workflow this way but if there's a demand for it this type of solution it can be realized.

If some real development effort is put into this a highly effective stitching solution could be made that wouldn't require that much computing time, with reservation for lots of moving stuff.

I'm a software engineer and I would enjoy developing such a solution, but I would not really enjoy using it for my own photography. I like the hands-on "mechanical craft" of photography and at some point the image making becomes too much of a technical exercise. It's all in my head of course, cropping and shifting on the computer screen rather than on directly on camera is not really a creative difference, but I just like the latter better.

There's also the Hasselblad system with the tilt-shift adapter which gives you quite many tilt-shift focal lengths. That you get movements recorded in the exif data and automatic lens corrections is a neat and unique feature. As it's a tele converter solution the quality is not Rodenstock but the automatic lens corrections make up some, and there's no LCC need.

That could be an interesting alternative for me personally as I like to have many focal lengths with tilt-shift capability, and I happen to have a H4D. The system would be super-expensive and super-heavy compared to my current tech cam system though.

I'm not really into maximizing resolving power at all costs, the shooting experience and compositional flexibility must be there too.

I stitch a lot, direct stitch where you are shifting the lens or back, here you can, somehow, easily combined different frames of the images so you can place people or not for instance....but if you start stitching around the nodal point, without shifting, as suggested here, you are asking for all kind of troubles with lines not lining perfect up and so on. If you have all the time in the world you can maybe make it work, but in a commercial workflow - that would be a challenge.

It's all about lines... ;-)

I stitch a lot, often buildings. There is zero issues stitching perfectly lines to the pixel when rotating a good lens around it's entrance pupil when using good pano software such as PTgui. This is simply a non issue. A recent example.

(https://farm6.staticflickr.com/5691/24091476545_876deaec30_h.jpg)

I also own a pro motorized head (Clauss Rodeon) that I can control with my iPhone or my soon to arrive Surface Pro 4. This head is super robust and can support heavy body/lens combos easily.

But there is still a potential problem with stitching in some cases when some vertical elements (typically a supporting column) are located fairly close to the camera. As the camera rotates around an horizontal axis when switching between rows, the distance to the vertical column changes, which results in differences of sharpness btwn the center and top/bottom of the column. Stopping down helps a lot and focus stacking fix this issue but can create some alignement issues. Here is an example where this issue occurs.

(https://farm6.staticflickr.com/5785/23686742960_25034bf82b_o.jpg)

I am sure that those who tried stitching seriously know about this problem, but this and the additional time it can take are IMHO the main issues with the use of stitching for architecture work. Time can be discussed as it may in fact not be that much more time consuming with an optimized workflow.

But this isn't the point I believe. I was hoping to be able to shoot with a FF DB on a tech camera using live view without having to care about weird technological issues with color impacts. In short I was dreaming of a real alternative to a 4x5 camera. From these initial reports it would seem that the IQ3 100MP still struggles to make this a reality and, if confirmed, this would be disapointing considering the price of such a system.

For what I do it pretty much kills the value compared to a potential Pentax 645X using the same chip at one quarter the price. Strobe shooters will still like the central shutter lenses of course, so this will probably not make much of a difference for a majority of IQ3 100MP shooters.

Bernard

IMO, the best camera to shoot architectural interiors is by far the Roundshot 220VR... One shoots 120mm (or 220 if he needs ultra panoramic look done with telephoto) film with it, but with a Nikkor 17-35mm f2.8 used at only two or three focal lengths (say 21, 27 & 35 - nodal point pre-found and noted for ever), one can shoot whatever wide angle he wants, at whatever height he wants and as for detail... well... you'll never (and I mean never) miss some... For exteriors one may need the Zeiss 15mm f2.8 additionally and the shift adjustment added (usually a standard), but then the result will be very hard to beat and there will be no scene that wouldn't prove "a piece of cake" for the system... Killer camera! It starts where hi-end photography ends....

A pro with CA or eveness issues is not going to order one of these 50K units in the hope she might find a lens that works when shifted. Besides which anyone smart enuff to ask the question is already stitching the Sony or doing multishot with a smaller back.

Due to a current Lcc bug in C1 it's easy to get confusing results currently. It's not yet clear where the shift limits are, but it looks quite good for 15mm on 40HR which will bring you far.

That the Rodenstock Digarons lenses and sensor don't match is clear and that crosstalk therefore is a factor and you don't get the full 90mm IC on the wides is 100% clear. But many shooters can do with a fair bit less, some say they need only 8mm of shift and for those this can work out just fine.

It looks like it has slightly less issues than the IQ250 but more than 80Mp Dalsa.

My reports can come out as negative as my personal interest is in larger shift ranges, and I am more concerned than most about crosstalk related color fidelity reduction

I am also concerned by the raw fact that the highest end sensor actually doesn't match Rodenstock designs and we need to push the envelope into the unknown compromise space like this. It's not how it should be and I am not particularly fond of that we as photographers need to do these evaluations. If it's 90mm IC it should work predictably to the edge and that was Rodenstock's intention. They couldn't predict Sony's sensor design though.

I'm also not happy about Phase Ones solid silence about these issues and that they never mention crosstalk -- crosstalk is an uncontroversial standard term in image sensor design and it's obvious that the special issues we have here is related to that. It's easily explained too. I don’t understand why Doug and other representatives are so reluctant to using this term. It's almost like they want photographers not know so they don't know what to look for and therefore buy without knowing what compromises they make when shifting.

Dear Bernard -

 You don't need to tell others what I think, I can do the telling quite well.

 I think institutions looking to do reproduction will buy the 100MP as a safe one-click hi rez digitizer, no surprises.

 I think pro photographers will do a very careful check whether the back works for them; if they know about shifting, then they will know about testing the shift before they buy.

 And lastly, I think that anyone who believes they can predict the shift properties, CA, vignetting  crosstalk etc of an unseen sensor with no datasheet and unqualified coverglass,when combined as a photographic system with lenses yet unused on this sensor, and make relevant contributions on this topic that others will base a $50K buy decision on is ... overenthusiastic.

 My take on the new Phase is that it is a safe buy but probably overkill for institutions, has in fact an affordable price for pros who have the customers who need the resolution - but they will need to check it out- and will make amateur buyers happy. My take on the tech forum contributions of late is a lot of people are talking in huge tech detail about topics they don't really know much about, and not enough about stuff they are good at, like in your case I would be interested in a discussion about how one gets good at stitching.

Hi,

A lot of things can be quite accurately predicted.

Folks have experience with existing backs. Highly unlikely that say Phase One would use thinner cover glass on IQ3 100MP than on older backs as the cover glass needs to be taken into account in optical calculations, at least on non retrofokus wide angle designs.

It is also highly unlikely that Sony makes a sensor in small series that radically departs from their standard designs. Some of their designs are BSI, though.

Now, folks have experience with existing designs like the IQ 250 and for that matter the A7rII, that is often used with shift. Also, Alpa has shared some shifted images, so you can test expectations against actual sample pictures.

Best regards
Erik

Phase haters after the IQ series:

" Sure they have a good screen now, but who uses CCD anymore? CMOS is the future! Who pays 5 figures for this crap when my **Insert Canikon** has a CMOS sensor?"

Phase haters after the IQ 250:

" 44x33 is barely MF! Who pays 5 figures for this crap when my **Insert Canikon** sensor is almost as big?"

The latest tests of the tech camera lens combo is over at getdpi, and it now looks more promising than before. A recent version of Capture One had LCC bug which made some of the initial tests look bad.

My current guess is that I think it will be popular among tech cam users, perhaps more so than the IQ250.

Crosstalk is something us tech cam users need to get used to though because we can no longer count on getting sensor designed for out lenses. You can see it as a sort of gradual image quality falloff like corner sharpness, a "color fidelity vignetting" if you like. All sensors have some pixel crosstalk even when light comes in straight on, but here it becomes higher than normal. Fortunately as most natural color are low saturation you can have pretty high amounts of crosstalk without much or any visible effect. You could say that in center the camera is probably the best so far regarding tonality, while in shifted areas the tonal separation is probably more similar to a mobile phone camera, which still is okay. Not all will enjoy this type of compromise with a $44k back, but tonality is overrated anyway, people think they can see it but few actually does, what people can see is pixel peep noise and sharpness and here it looks very good.

Thanks for the update. These look like good news. I guess that Doug's results will probably confirm these findings with the Rodenstock 40mm lens. Still interested in seeing how the 32mm behaves though.

I'd also be interested to see some results with lenses being tilted. Could such tests be made also?

Tilt? Now you're being old-school ;) many cameras used in the tests don't even have tilt capability and since tilts usually is like 1-2 degrees when it comes to wides it doesn't make that much of a difference, so I would not worry about that. I use tilt and swings myself quite frequently but have never run into issues of that it changes color cast significantly compared to the basic shifting, and from a pure geometric perspective it's the expected result.

It should be noted that Rodenstock wides have varying degrees of retrofocus, longer lenses have less meaning that longer lenses can stress the sensor too. The Schneider Digitar 60XL is still a very popular high end lens but as it's symmetric and can do large shifts you can run into issues with that too despite the relatively long focal length. Of course if you do product/macro photo you may be using large tilts and might run into issues but I doubt that becuase the macro focal length is typically ~120mm.

Hopefully good results can be had with a shifted 32HR too, most certainly not to the 90mm IC edge but that 10mm shift in the Alpa shot may be feasible. I suspect Alpa used a buggy C1 version for their posted test shots. We'll see in the next few days.

I've only seen landscape orientation shifting so far. The IQ250 sensor is more robust in portrait orientation, but my old Dalsa was more robust in the landscape, it depends on chip wiring (the wiring is in front and works like a crosstalk barrier), and I've seen Dalsas wired in both portrait and landscape directions. That is we can't be sure the IQ3100 sensor has its wiring oriented in the same way as the IQ250 so we should wait for portrait results too. It's quite certain that this is not a BSI sensor, based on rumoured inside information and guesses from the behavior seen so far. BSI is probably not mature enough for this size, and probably not mature enough when it comes to maximizing base ISO DR.

Cool, I am the tilt guy now! ;)

In fact I believe that tilting downwards for typically landscape application does move the sensor closer to the edge of the image circle also, so it does change the angle. It just does it less than shift because the amount of tilt typically used is less.

It does, which slightly changes the composition. However, a rise/fall adjustment will counter the effect, while preserving tilt.

I still have mixed feelings about this but am excited to see more.

Phase, IMO, need to create a motion back. This is plausible after all and I would feel far, far more comfortable and interested investing such a sum in the system that could cater more securely for the future.

Also if Zeiss would jump in on the Medium Format game (and if Phase One allowed it) and could re-instate/re-design some of the exciting designs they own, namely the 110mm f2 and 80 f2 then I would get very, very excited.

For me, equipment is still too much in transition and it is very difficult to find a system that caters for my commercial needs and also aesthetics.

Haven't seen that before so I don't dare to guess. I'm also curious about why they got a bug now, maybe because they're making some sensor-specific LCC improvements due to some specific issues with this one. When I get time and files I'll do some own probing, very curious to see the good, the bad and the ugly under the software correction surface.

Well, Kevin and I spent yesterday with the new back and my Sony grabbing some interiors of really beautiful spaces.  It wasn't an ideal test, as neither of us had the lenses that you would really want to use with this back for shooting architecture.

I've also had a look at the tech cam tests on GetDPI and was glad to see those.

I'm going to do a write-up over the next few days with images, but wanted to drop my initial thoughts.  The Sony holds up decently against the digital back, decently.  I've always known that the A7r files we're not as pretty but felt that they could be worked in post to get where I needed them.  When you start pulling up shadows, however, The Phase really seems to shine and exhibits less noise.  It also has better color, micro-contrast, DR, and sharpness out of the box.

I don't have any great wides left from my tech cam kit but still had this Rodie apo-sironar digital 45mm kicking around so I used that for both these shots.  I didn't employ any movements, because I didn't feel the lens would hold up to it.

So, you can definitely get the nicest files out of the digi-back.  It is, however, way less convenient to work with and from what I've seen, there will be less shifting available than there was with my IQ260... no matter what lenses you buy.  I'd really love to make this back work for me, but I just don't know if I can live with less movements.  As a 20+ year veteran of professional architectural photography, I'm beginning to feel like my dream system may never exist.

More to come...

IMHO

Both images on the MF2, Rodie 45mm, f/11, 2s, base settings with 50/50 hilight shadow recovery (just for yucks)
The Phase feels sharper, but focus could have been off a touch on the Sony, so nothing conclusive there.

Kevin has the 23mm Rodie HR.  I don't have any samples.  He didn't employ any shifts, but from what I saw, that lens is TOTALLY usable on the 100 when centered.

Thank Chris.  Initially misread what you posted.  That is great news!  I don't shift that lens on the IQ180 anyway.  This could be very good!

We'll have sample images from the 23mm to show in a follow up article soon.  The LLC part of C1 has a small bug in it so waiting fro Phase One to correct that.  We can then do a final process on the 23mm.  Thanks Chris for the great day, as always was fun shooting and chatting with you.

The new 100MP back certainly looks impressive from initial reports. I think the ideal all round architectural camera would be a Sony mirrorless with a 33x44 sensor of 60-65 MP. Such a camera would offer a good combination of cost, quality and speed when paired with T/S lenses via adapters.

Even better if Canon would update their 45 and 90 TSE lenses, and also produce something in the 32-35mm range, maybe a 65 TSE as well. Alas, neither the camera nor lenses exist at this point, but one can always hope.

Hi Chris,

Thanks for sharing images and observations!

Best regards

Well, Kevin and I spent yesterday with the new back and my Sony grabbing some interiors of really beautiful spaces.  It wasn't an ideal test, as neither of us had the lenses that you would really want to use with this back for shooting architecture.

I've also had a look at the tech cam tests on GetDPI and was glad to see those.

I'm going to do a write-up over the next few days with images, but wanted to drop my initial thoughts.  The Sony holds up decently against the digital back, decently.  I've always known that the A7r files we're not as pretty but felt that they could be worked in post to get where I needed them.  When you start pulling up shadows, however, The Phase really seems to shine and exhibits less noise.  It also has better color, micro-contrast, DR, and sharpness out of the box.

I don't have any great wides left from my tech cam kit but still had this Rodie apo-sironar digital 45mm kicking around so I used that for both these shots.  I didn't employ any movements, because I didn't feel the lens would hold up to it.

So, you can definitely get the nicest files out of the digi-back.  It is, however, way less convenient to work with and from what I've seen, there will be less shifting available than there was with my IQ260... no matter what lenses you buy.  I'd really love to make this back work for me, but I just don't know if I can live with less movements.  As a 20+ year veteran of professional architectural photography, I'm beginning to feel like my dream system may never exist.

More to come...

IMHO

Both images on the MF2, Rodie 45mm, f/11, 2s, base settings with 50/50 hilight shadow recovery (just for yucks)
The Phase feels sharper, but focus could have been off a touch on the Sony, so nothing conclusive there.

A problem for the tech camera genre is that pixel technology is merging to be the same in 135 and MFD.

Before medium format sensors where in a zone where they could both have a bit higher pixel count and at the same time a larger pixel, and they would also allow themselves to waste some high ISO performance by not having micro lenses.

This allowed medium format sensors to function with lens designs that was impossible on the smaller formats, which is symmetric or weak retrofocus wides, providing a unique feature set, near distortion-free lenses with a large range of movements.

Now with pixel sizes just as small on MFD like on 135, and the same desires regarding ISO performance, the same limitations regarding lens designs is there which means that lenses must be designed in the same way as for the smaller formats.

It's quite obvious that both Rodenstock Digarons and Schneider Digitars are both obsolete in terms of design when it comes to supporting the new MFD king, Sony, but thanks to the extremely good tonality and dynamic range of the Sony some of this over-capacity can be used to do the impossible. Due to subject- and condition-dependent gradual degradations of image quality in shifted areas its hard to quickly get a grip of exactly how these systems perform. I'm myself thrown between hope and despair. It will for sure make images on the wides with quite large shift range, but when does the subtle color degradations become "too much"? That's the hard part...

MFD surely has got better and more all-around with CMOS, but it has also lost some of its originality. It's not really CMOSs fault as such, but rather the inability to focus on other properties than megapixels and dynamic range. Had they made a 60MP version put in some light shields in the design, and perhaps dropping or at least reduce the aggressiveness of the microlenses I think it could have been the most tech cam friendly sensor ever. When BSI then arrives they could reduce well depth and then start increasing pixel count again without losing angular response (when you have deep wells you need large pixels to have good angular response, it's simple geometry)

If I would have had the power to adjust the CMOS design target I'm not sure if I would have changed them from the current though. There's a reality out there and indeed I think megapixel is king, to stay attractive MFD needs to keep a good megapixel distance to the current 135 which is at 50 now. It's really not about lens quality, that is a too complex discussion, just hit them with the head with twice the amount of megapixels and watch it sell. Holding back ISO performance and megapixels to keep the wide angle tech cam niche happy just isn't worth it from a business perspective, it's then better to try convince the niche run on a back which isn't designed for them. Ideally one would make two sensors with different design targets, but it's probably unrealistic from a development cost perspective.

Hi Anders,

I am not so sure about the thing about well depth thing.

I would also guess that Sony is going after the main market and that is probably MF DSLRs. Personally, I feel MF needs to go mirror less. After all, who needs that flipping mirror just to show a mediocre image on a mediocre ground glass. The idea I really like is a technical camera with a high quality EVF, magnified LV and focus peaking. But sorry, if I cannot afford I will not buy…

Yes it's a main market thing. Tech cam wide photography with large shifts, eg architecture photography, is just too small a niche to care much about. If you can only make one sensor, make it for the key segment and try to shoehorn it into the others. And it is very much shoehorning going on right now in the tech wide tests I can assure you... not sure yet how that will end.

While I agree that on tech cams ground glass image is mediocre due to the high vignetting lenses and low angle of incoming light, I don't think the mirrorless discussion apply to the MF DSLRs. The image you see in the optical viewfinder is good, just like on the 135 Pro DSLRs. It's even better in MF as it's larger. As you're using auto focus you don't have the problem of messing around with a loupe on it either. I think the typical studio photographer, which is the main customer segment, will want to use an optical viewfinder for at least a handful more years so I don't think we'll see mirrorless for the H or XF system anytime soon. I also think Canon/Nikon's flagship models will stay optical viewfinder for quite long, as the key market of pro customers simply like it, and there's some technical reasons too related to the possibility to have a dedicated auto focus sensor which is currently performing much better for telephoto than on chip phase detection.

Hi Anders,

Your points are well taken, but the mirror causes vibrations. Shooting with my Planar 120/4 on my Hasselblad 555/ELD at say 1/125 without mirror lock up just produces crap even if I am shooting on top of an RRS Versa 3S with an ArcaSwiss D4 head.  I also think that phase detection combined with contrast sensing AF can give superior results, unless shooting fast action, and I don't see a lot of MFD at Formula One or horse show jumping championships.

Now, it is very well possible that new cameras have a better damped mirrors. The new Phase One camera has an almost vibration free LV mode. But I think the SLR concept belongs to history. A magnificent piece of history, but history nevertheless.

you can have mirror, dedicated AF sensors and yet EVF, even w/o dSLT (like the current Sony fixed mirrors) - put a better small sensor where the prism is, it can do both metering & color tracking (which is anyways already there) together with dedicated AF sensors (where they are now, below the mirror box) and let it feed EVF...  as it is not the main imaging sensor it can be just optimized for metering/tracking/EVF purposes leaving the main sensor rest till the exposure time...

As a 20+ year veteran of professional architectural photography, I'm beginning to feel like my dream system may never exist.

I'd love to hear at some point what the properties of such a dream system is.

Mine is pretty simple - a CMOS digital back that is designed to work to the edge of the image circles of the currently available Rodenstocks Digarons and Schneider Digitars. I can live with the LCC and lack of integration mess, but I really would love to be able to just care about the optics, its image circle and sharpness and not worry that the sensor can't handle my movement settings regardless what I set them to. And then to dream further I would love if Schneider with proper sensor support had stayed in and continued with their more traditional designs for us that prefer that instead of maximum-sharpness-at-all-costs type of designs which Rodenstock represent. They were really complementary brands, but Schneider was let down by the sensors making it impossible to make reasonable business with their lenses.

I guess that now we're pushed towards making center frames and adjusting perspective in post-processing. With the ultra-high resolution we're getting it seems feasible from a quality perspective. I haven't really thought about if that is a less productive way to work or not, but it surely is less pleasing as I see it.

What I dislike most about doing keystone correction in post is the fact that I totally lose control over composition while shooting (I have a background in architectural photography, and use a Credo 40 on a Linhof Techno for most of my work).

I recently added a Olympus OM-D E-M5 Mark II to my setup, and I really like its "digital keystone compensation" feature, which lets you correct perspective (both vertical and horizontal) live on the camera screen (or viewfinder) while shooting. This way you can effectively "shift"  and compose properly, and you also don't have to find out in post that you have to crop too much after keystone correction and should have chosen a wider angle lens. The out-of-camera JPEG comes corrected, but RAWS are untouched, and you can apply the same level of correction in post (which, if I remember correctly, is something you can also do with the IQ backs in C1, which is able to automatically read out the roll and pitch data from the IQs gyroscope).

As Anders said, the loss of resolution is note an issue anymore with 100mp. At least for me, it is not even an issue with my meager 40mp back most of the time.

I'm also not happy about Phase Ones solid silence about these issues and that they never mention crosstalk -- crosstalk is an uncontroversial standard term in image sensor design and it's obvious that the special issues we have here is related to that. It's easily explained too. I don’t understand why Doug and other representatives are so reluctant to using this term. It's almost like they want photographers not know so they don't know what to look for and therefore buy without knowing what compromises they make when shifting.

(I switched from an Aptus 75 to a Credo 40, because the Aptus had no live view. And, unlike some people here in the forum, not being good at ground glass composition and focussing, I had to shoot tethered to a laptop even on location, which was a drag.  While with the Aptus 75 I could shift my heart out (20+ mm) and never had problems after the LCC, with the Credo 40 everything above 10mm starts to be a problem. But the buildings I shoot refuse  to get shorter, maybe I should get a drone). Crosstalk is a real issue for some of us.

Okay, if I assume that RawDigger (RawDigger-1.2.3.435-x64.exe) reads the ISO 50 sample file correctly, then this is what I find:

ReadNoise (standard deviation)
R=5.04
G=5.04
B=5.03
G2=5.02

Blacklevel
Offset=1024 (automatic, the mean of the masked pixels is 1025.7, 1025.2, 1025.4, and 1025.4)

Saturation
R=65532
G=65532
B=65532
G2=65532

So for Dynamic Range I get for the green channels Log((65532-1024) / 5.03) / Log(2) = 13.65 stops dynamic range, instead of 15 stops. I'm not sure if the camera's 14 or 16 bit mode was used for this shot, but 13.65 stops is still impressive.

Again, this assumes that Rawdigger reads the file data correctly, and that the masked photosites contain only read-noise (QED).

Cheers,
Bart

Now that we have received our unit and have done a shoot with 16-bit mode turned on I can confirm the previous raw files (ISO Sweep of the city) was done in the 14-bit mode.

Hi,

It looks interesting, at least in my version of RawDigger. The low numbers definitively look to be 14-bit as only each fourth bit contains data. Going up to say 100-200 levels the gaps start to fill in.

I have the latest version of RawDigger, but Phase One cameras above IQ-280 are not officially supported it seems. So it can be that RawDigger would interpret something wrong. Still it is very odd.

A small comment to Doug, it seems that focus is bad on the f/10 image, as the f/14 is far more distinct.

Best regards
Erik

Possibly, guess we’ll see if Phase wants to make a new body and new line up of lens that eliminates the mirror box. As it stands now, I don’t know if any company has the interest in expending R&D to develop a mirrorless MF system to replace the current dSLR systems.  Tech cameras are great, but for many they don’t fit their shooting needs (either from a personal or a practical point of view)  Personally for some things an EVF still isn’t great ... the new XF viewfinder and fast focusing along with focus calibration is pretty sweet.  With the LS lenses, i haven’t seen mirror vibration an issue, even with the 240 LS on a tripod but not mirror up mode. still need to do more testing on that though.

Hi,

Yes, I think leaf shutters are pretty vibration free.

One thing I noticed in the raws I downloaded from Digital Transitions is that the exif data has fields for tilt and shift. The only camera that I know of that registers T&S is the T&S adapter for the Hasselblad, but Phase May also be working on something. I would also agree that EVF-s are "not there yet" for viewing but I also find it far more comfortable to focus trough the viewfinder than on LCD.

Hasselblad has user set able delay between mirror release and shutter release, but that of course increases response time. With the vibration sensor it is possible that that XF delays shutter release until vibrations decay.

Lots of interesting stuff going on.

Erik

Hi, you will need to use Capture One v9.0.2 or later to convert the 16-bit IIQ file into DNG first. RawDigger v1.2.3 does not support the 16-bit IIQ file.

RawDigger format reader is based on dcraw. Dcraw didn't even support P65+ and later properly until last year when I personally added support and sent it to Dave Coffin (Dcraw author) which got it integrated into Dcraw, and then it propagated to all software using dcraw in one way or another, including RawDigger.

Dave doesn't prioritize the MFD formats very much an no other of the open source guys either except for, well, me. CCDs especially are a mess as they depend so much on calibration data, that is you get to display an image quickly but to do it right you must reverse engineer and apply the calibration data too. CMOS are not as dependent on calibration data fortunately, but as RawDigger/dcraw seems to read the 16 bit files the 2 extra bits are probably stored as some extension or something.

The raw data is read in the function phase_one_load_raw_c and you can see on this magic line:
      i = (pixel[col] << 2) - ph1.black + cblack[row][col >= ph1.split_col] + rblack[col][row >= ph1.split_row];

that the real data pixel[col] is shifted up two bits from 14 to 16 (the << 2 operator), that is the current decoder can only read 14 bit real data like the format was before (yes also including for the "16 bit" CCDs...).

Someone's got to look into what the format differences in the new 16 bit encoding is and decode that properly and provide that to Dave/Dcraw, then it will end up in RawDigger eventually.

And no, Phase One won't help out. I've of course asked. If I don't do it it will probably stay half-supported for years, just like the P65+. Maybe I'll take a look, but I must say that I really really hate reverse-engineering formats. It's hard coming up with a more frustrating time-wasting experience in the world of programming. The only reason I've done it is that I hate closed camera formats even more.

Hi,

It looks interesting, at least in my version of RawDigger. The low numbers definitively look to be 14-bit as only each fourth bit contains data. Going up to say 100-200 levels the gaps start to fill in.

I have the latest version of RawDigger, but Phase One cameras above IQ-280 are not officially supported it seems. So it can be that RawDigger would interpret something wrong. Still it is very odd.

A small comment to Doug, it seems that focus is bad on the f/10 image, as the f/14 is far more distinct.

Best regards
Erik

I recently added a Olympus OM-D E-M5 Mark II to my setup, and I really like its "digital keystone compensation" feature, which lets you correct perspective (both vertical and horizontal) live on the camera screen (or viewfinder) while shooting.

Yes I think this can be the future of wide angle "tech cams", that the camera itself really only shoots center frames with a super-sharp ultrawide and then you do shift composition directly on live view, which is done in software through cropping and keystoning. Maybe within 5 years. If digital backs start supporting third-party "apps" much like mobiles and tablets it may be quicker, and I think app-supporting cameras is going to happen but on the smaller formats first of course.

If you can do it like that directly when you shoot on live view, then the experience will be quite similar to turning knobs and wheels on the tech camera, so I guess I can live with that. At that time there may be built-in automatic fast focus-stacking too so tilt is not necessary.

Personally I don't produce professionally but try to make some sort of photography art, so then the shooting process is not only about end result and production efficiency. The shooting process must feel right. I think I've never been as close to start seriously thinking about shooting film. I'm indeed a software engineer, but when I do photography I want it to be something else than my profession, and when it starts becoming more and more virtual it stops feeling right.

Not really, as the IIQ decoder in libraw is based on dcraw, right? Seems not being a good thing if several people do the same reverse engineering work. Passing it through dcraw is not a great way to collaborate, but as long as Dave does his thing it seems to be the least bad way. I hope RawDigger folks share their format findings with the open source community in some way. My stuff usually ends up in RawTherapee first (which is open source) and then I make a dcraw patch and send it to Dave which he usually rewrites to his very special coding style and removes all comments and then he puts it into the official dcraw release, which gets into LibRaw and other projects that follow dcraw updates.

Anyway, I've made some tests and it seems to be a one liner to fix:

RawDigger version 1.2.4.437 supports both IQ3 100MPix formats, 14-bit and 16-bit; available from our site at http://www.rawdigger.com/download

...or in the same sense that libraw actually imports dcraw.c and rawspeed (just see their changelog) plus makes some own development. I'm sure IIQ Dalsa calibration data code (my code) came in that way (just checked, it's in internal/dcraw_common.cpp). But anyway it doesn't matter for this discussion. Great that RawDigger has IQ3 100 support now, I hope it's contributed upstream.

Hi, you will need to use Capture One v9.0.2 or later to convert the 16-bit IIQ file into DNG first. RawDigger v1.2.3 does not support the 16-bit IIQ file.

Hope this is not too far off topic (and has not already been mentioned) but was just wondering if this sensor uses the same Sony coverglass that is found in the A7RII?

Also, I know that everyone seems most keen to know how the tech wides work on this back but I would be really interested for Alpa to showcase some examples with either the Hasselblad H lenses or Contax 645 with their new shift adapter...

Due to both of the above designs, a lot of the issues being discussed here (and most going right over my head to be honest) would be less of an issue right?  As somebody who does not own a MFDB or any tech lenses, I was amazed to see the original files (before LCC correction) of those samples being displayed by Alpa..

As a newbie, I think using a lens that does not need a LCC correction would be appealing (at a loss of sharpness I am sure)..

Looking forward to all the future test that are sure to come :)

One last question, just wondering how the P45+ handles the discussed issues with tech wides?  Would it be a good one to aim for if I was happy enough with the resolution it offers..  (which is enough by the way).

Thanks a lot for any advice or input!

Hi,

The issue is not far off topic. I would be pretty sure that Phase One uses the same thickness of cover glass on all sensors. Any vendor would standardise on cover glass thickness as lens designs needs to take this into consideration.

I don't know the thickness of cover glass on the IQ-backs.

Cover glass has nothing to do with colour shifts, the colour shifts are related pixel depth, microlens design, light leaks between pixels.  The only problem cover glass is causing is astigmatism.

Also, cover glass is normally the IR filter. Leica reduced it's thickness to 0.5 mm on the M8 and got a lot of issues with IR contamination.

I'm starting to hear that the high ISO performance of the back may not be as good as IQ250 for example. Has someone made any analysis of this?

I made a quick comparison "by eye" on an ISO3200 shot and then it compared well per pixel with an A7r-II, I'd say the IQ3100 may even be a bit cleaner. This is in RawTherapee without any preprocessing noise reduction magic, that is you see the raw sensor performance.

1.  I think you'd want to use LCC pretty much all the time.  It corrects things other than color casts like vignetting, dust etc.
2.  The P45+ is a great back for tech cams.  It is close to full frame in size, supports long exposures very well, works with pretty much all lenses (and you can et some great scneider wides cheap for it), It can be had for a bargain these days, and it has nice fat pixels.  Two draw backs are the screen, which is just plain crappy, and FW vs. USB for tethering.  If you come to terms with image review and focussing on the overall system you choose, it is a great back.
3.  rodenstock, on specs on their website is stating that their lenses account for a 2mm thick sensor glass.  Given that Phase/Leaf backs are likely the most common on tech cams, i'd think this is close to the thickness of the sensor glass.

Hi Ken,

Yes of course, no one in full use of their faculties would consider anything else. There is no substitue for square inches. If you take a Sony sensor and make it 2.5 times larger it will deliver 2.5 times the pixels of similar quality.

But, the A7rII having the same size of pixels is a good tool to estimate performance of the larger sensor. As both pixels are coming from same factory, same designers and probably a similar process. The A7rII sensor is backside illuminated, which may lead to somewhat reduced DR (something like 1/2 EV), but may have other benefits.

My first impression from the first images Doug has posted were not so great, it is nice to hear that Kevin's and Chris's test shot prove me wrong. The images from Copenhagen had very bright sky. They were properly exposed to the right, according an older version of RawDigger but mid tones needed pushing a lot, and I observed some ugly colour noise, which I have not expected. But I guess I was a bit to demanding, or some bug in Capture One. Anyway good that Chris gets results he is happy with.

What I have seen before is that Pentax and Nikon pull a bit more performance out of the Sony sensors than Sony them selves. It may even be that Phase One needs that extra bit. Nikon D810 is very close to 14 bits in DR, but the Sony A7rII is a bit behind, it is even a bit behind the A7r, in that regard.

Yes, it seems the D810 gets the most DR out of the sony 35mm sensor.

Low iso performance is definitely a priority on a back like the IQ3 100MP while the A7RII being a much more consumer oriented product is tuned more for high performance across the whole iso range with obvious bumps (compared to the D810) in performance at several iso settings.

I have no clue what each company does on top of what the sensor can deliver from the factory or if some changes are made inside the sensor itself or if its a combination of hardware and programming (on sensor).

I don't think anyone without a signed NDA really knows.

I though Sony improved the depth and DR of the A7RII with the new firmware? and got it to 14bit.

Hi,

The Sony A7rII has a special trick called the Aptina Patent. They reduce full well capacity at 640 ISO by disconnecting an internal capacitor. That reduces readout noise a bit. At real high ISOs they probably just kick in noise reduction.

Quite smart actually.

I've done a bit more Read-noise and Dynamic Range number crunching based on some more files, and at different ISOs. The conclusion is that the 16-bit lossless mode does add DR compared to the 14-bit 'lossless' mode, but it remains a bit below the claimed 15 stops. Also, there is no real difference in readnoise between nominal ISO 50 and ISO 100. Read noise for ISO 3200 and above remains unchanged, so becomes basically ISO-less.

Attached are the summarized 14-bit mode shot results of the 'Roundtower' sequence. The numerical differences between the R/G/B/G2 color planes are marginal, they all show very similar values.

I've used RawDigger Version 1.2.4 Build 437 (which is supposed to read the 16-bit mode correctly) to read the files. The DR of 13.65 stops at nominal ISO 50 in 14-bit mode, change to a DR of 14.39 stops in 16-bit mode (not quite the claimed 15-bits but still very high).

Read noise drops from a standard deviation of 5.03 DN to 3 DN, at ISO 50 (and I assume at ISO 100, but I have no file to verify yet). Base ISO therefore seems to be nominal ISO 100. We'll see when DxOlabs publish their analysis how they rate the real ISO sensitivity.

At ISO 800 the DR changes from 11.66 stops in 14-bit mode, to 12.06 stops in 16-bit mode.

The observed 4-DN combing of the histograms in 14-bit mode, indeed disappears in 16-bit mode, so the electronics do seem to produce 16-bit native signal levels, with a noise floor in the 1.61 LSBs (least significant bits).

Low ISO read-noise is very low, and DR is impressive, assuming these files are representative for a larger population of sensors.

Hi,

I guess that Sony/Phase One really pulled that rabbit out of that hat!

As far as I recall, Nikon D810 was the camera with the highest DR (at the pixel level), and DxO measured that camera to 13.67EV, so this reaches 14.39 (according to your calculations) and that is quite a bit more.

On the other hand, I have noticed that D810 was close to 14 bit limit and DR. Going to 16 bit may have been needed to fully utilising those sensor pixels.

Seems like Phase One put together a really impressive back!

Hi Erik, yes that is indeed impressive (and so are the filesizes of course).

It may be that with a bit of tweaking of the sensor calibration/stitching/LCCs/NoiseReduction one also achieves a superior 'photographic DR' and not only an engineering DR. Something else I noticed earlier with a DCamProf profile for the EOS 5Ds that 'AlterEgo' made available in that application's main thread, is that the profile may have a significant (in that case positive) impact on the demosaiced and rendered noise. So the Raw conversion quality also makes a difference.

Absolutely. Outputting more than 14-bit data from the ADC (by whatever means) is necessary to exceed the 14 stop boundary.

They sure did. I think it's not just the Sony sensor that made it possible, but we can only be sure if others start using the sensor as well.

You're welcome.

I wanted to satisfy my own curiosity, and I don't mind sharing what I've found so far. Much more can be done to unravel the under-the-hood state of affairs, but that would require constructing Photon Transfer function curves for the different color planes at different ISOs. That would be a lot of work, based on image pairs at many exposure levels that need to be subtracted to isolate pattern noise, Read noise, reset noise and photon noise, and determine ADC gain and other things that one might stumble on. So far there seems to be no White balance preconditioning, but maybe something like that will show up at specific settings.

That was an "aha"-experience during the development of DCamProf. It's not a good idea for the profile to push saturation of darkest shadows a lot, as it just makes the chroma noise more visible....

Hi Anders,

Indeed, and it's very effective in restraining the not very noise free 5DS Raw data conversions. The IQ3 100 sensor needs a lot less help with its 3 stops better DR, but it won't hurt either for less well controlled lighting conditions, e.g. landscape and natural light architecture, or at higher ISOs.

14.39 is very impressive indeed.

In fact, it needs only 0.11 more to be 15 stops (as opposed to 15.0 stops).

This is probably within margin of error.

Hi Jim,

In my simple tests I did not see an improvement in dark noise. But I have noticed that dark tones that were pushed 4-5 stops remained neutral grey with the new uncompressed formate but went like brownish with the old formate.

So I felt the new file format yielded more neutral colours in extreme pushing. I did not come up with an explanation for the effect.

I have some samples, if needed, but it would take some time to find.

Could some please provide a link to this thread?  I had a look but couldn't seem to find it. 

Thank you

I've done a bit more Read-noise and Dynamic Range number crunching based on some more files, and at different ISOs. The conclusion is that the 16-bit lossless mode does add DR compared to the 14-bit 'lossless' mode, but it remains a bit below the claimed 15 stops. Also, there is no real difference in readnoise between nominal ISO 50 and ISO 100. Read noise for ISO 3200 and above remains unchanged, so becomes basically ISO-less.

Attached are the summarized 14-bit mode shot results of the 'Roundtower' sequence. The numerical differences between the R/G/B/G2 color planes are marginal, they all show very similar values.

I've used RawDigger Version 1.2.4 Build 437 (which is supposed to read the 16-bit mode correctly) to read the files. The DR of 13.65 stops at nominal ISO 50 in 14-bit mode, change to a DR of 14.39 stops in 16-bit mode (not quite the claimed 15-bits but still very high).

Read noise drops from a standard deviation of 5.03 DN to 3 DN, at ISO 50 (and I assume at ISO 100, but I have no file to verify yet). Base ISO therefore seems to be nominal ISO 100. We'll see when DxOlabs publish their analysis how they rate the real ISO sensitivity.

At ISO 800 the DR changes from 11.66 stops in 14-bit mode, to 12.06 stops in 16-bit mode.

The observed 4-DN combing of the histograms in 14-bit mode, indeed disappears in 16-bit mode, so the electronics do seem to produce 16-bit native signal levels, with a noise floor in the 1.61 LSBs (least significant bits).

Low ISO read-noise is very low, and DR is impressive, assuming these files are representative for a larger population of sensors.

Cheers,
Bart

Hi Bart,

Thanks for your input. I have analyzed the darkframe shots I made. For the IQ3100 case it was shot in 16-bit mode. I used RawDigger 1.2.4 (black level=0) to manually select a sub-region in each darkframe to avoid tiling of readout noise. Then I used the following to calculate the dynamic range:

DR = ln( (65535 - mean(darkframe)) / std(darkframe) ) / ln(2)

It appears that the DR of this new sensor is really great!

See attached plot:

Hi Jim,

In my simple tests I did not see an improvement in dark noise. But I have noticed that dark tones that were pushed 4-5 stops remained neutral grey with the new uncompressed formate but went like brownish with the old formate.

So I felt the new file format yielded more neutral colours in extreme pushing. I did not come up with an explanation for the effect.

I have some samples, if needed, but it would take some time to find.



I've noticed that, too.  Take a look at these asymmetrical dark-field histos in compressed mode:

I'll look around and see what else I can find.

Does colour reflected by a sensor's physical surface visibly change as pixel density increases, similar to the way in which colour reflected by CD/DVD/Blu-Ray visibly changes as pit density increases?

Eric, I found the testing that I did that bears on that point:

It quantitatively validates your findings. The bias is low, and will not be material for most photographers, I think.

A 4.6 micron pitch will mean that at f/5.0 or narrower, diffraction will start to function as an OLPF of sorts, to reduce aliasing effects even further than the dense sampling already does, and apertures of f/16 or narrower will lose effective resolution due to diffraction...

Setting aside advice not to shoot at an aperture of f/16 or narrower for exactly that reason, what can one say if one does? Does deconvolution sharpening return zero benefit?

Hi,

When MTF at Nyquist reaches zero, no more detail can be recovered regardless of sharpening method.

But, visual perception is dominated by low frequencies and they are still improved by sharpening.

Another way to see it is that system MTF is like:

MTF(system) = MTF(lens design) * MTF(diffraction) * MTF(sensor)

Increasing MTF for any part still improves MTF(system) unless any part goes to zero.

I would suggest that diffraction needs to be taken into account when stopping down for DoF. The CoC in the calculation should be larger than the diameter of the diffraction disc. Bart can explain the fine details, he has both the math and the language skills :-)

Best regards
Erik

Hi,

That is angle dependent. So different spectral line will be have maxima at different angles.

Best regards
Erik

In layman's terms, is that a "Yes"?

Hi,

If you look illuminate and look from the same angle you would see a different colour.

Hi Anders,

 Re. chroma noise,

 I attended a session of the phone camera quality group of the IEEE, and they did some user testing. Surprisingly, consumers prefer chroma noise to luma noise. Photographers do not, the result was viewed as correct but counterintuitive by group members after the user tests were repeated. This may influence a choice of profile creation.

Interesting! I didn't know that. However my initial guess this has a larger effect on how to design noise reduction more than affecting profile design. What I do with profiles is avoid pushing saturation as much in the noisy range as colors are unstable there anyway.
