Re: the next phase of the color wars: Kodak vs Dalsa vs Sony

Hi Bill,

No, I guess that it will be a CCD vs. CMOS war before anyone has seen any real images from the IQ 250. Folks don't know about TrueSense and Dalsa but feel strong about CMOS vs. CCD.

Best regards
Erik


I predict a new internet forum war over the color look of Sony vs Teledyne-Dalsa vs Kodak/Truesense designs in formats larger than 36x24mm. After all, there have been fans of the "Kodak look" for a long time, going back to the era of Kodak full frame CCDs in early Olympus Four Thirds cameras. Indeed, there could be differences between these companies n their expertise and approaches to sensor color science.

Hi,

Some pretty serious people. Diglloyd to begin with, he used:

RRS TVC34L at 5' 3"
Arca Swiss Cube with RRS B2-Pro-II
RRS B6 plate on the A7r
2s self timer with wireless remote.

Jim Kasson measured it, 1/3 of the vibration level of the D800 (without MLU I guess)

RRS TVC-44, RRS BH-55

Joseph Holmes

Best regards
Erik



Lloyd Chambers also said in the same article that 'Field conditions cannot be any better than this studio set up, only worse' (direct quote).

Well, I tested my A7R on a tripod in my backyard in 'field conditions' using a 600mm Mk II Canon lens with the metabones adapter. At f4 (wide open), at 1/10s, there is NO shutter shake. Sure the image gets a bit sharper at f5.6 1/800 sec, but you would expect that.

Shutter shake is independent of tripod/hand held status. And, any shake/vibration/motion blur would only get magnified at long focal lengths and slow shutter speeds. I found nothing from 1/10 to 1/800 that would suggest shutter shock.

I do not deny Lloyd Chambers findings. Only saying I have not been able to duplicate them.

Hi,


As a side note, both the Alpa FPS and the Hartblei HCam use a Mamiya focal plane shutter and it is supposed not to cause vibrations on those cameras, but shutter vibration has been reported on the Phase One cameras, AFAIK, so it is an interesting question.

Best regards
Erik



Erik..... I have news for you.  The FPS has big time shutter shake which is very noticeable with longer lenses.  I know this for a fact as I have bought, tested and returned for that reason.

My only regret is posting a crop of one file processed to my taste - it's a poor way to show off the high-ISO quality on this back.



Doug,

Have a safe flight and hope you enjoyed Hong Kong.

I love it there.  It's like NY modern and our crews are amazingly good and huge fun.

I've made that flight 3 times and dig it because I can sleep runway to runway.

Hey, don't feel bad about the samples you posted.  You just posted what you had, but honestly Phase isn't the only company to produce "c__ppy samples" at camera introduction.

In fact those wedding photographer samples are good compared to the stuff PDN ran.  Those are beyond explanation and the only thing worse is PDn and the photographer raved on about them.  

Now that's scary.

Honestly though when they've had that camera out for testing for I assume a good period, why not produce better imagery?

Personally, I'm not a fan of most cmos because in most cases I find it weak especially when stretched to anything over 1200 iso.

What surprises me is when I compared it to this Olympus em-5 image at the Sony store at 1000 iso.  This was the worse lighting ever, with mixed tungsten, tv lcds, led's blinking, mall lights strobbing.

We're talking about a camera that retails now at $800 and I purposely didn't add any noise reduction because I liked the look and when Phase talks about "film grain look", they need to talk to olympus.



I'll admit this is not a pretty photograph, but I'm not throwing it on my site or creating a blog glowing about it.

Here's the same iamge at 100% processed from a jpeg of all things and cropped with 1/3 taken off.

http://tinyurl.com/olymus-at-100-1000iso

What I expect from a $35,000 is much more than this and I don't think the samples showed it.

Obviously this image is medium format territory with studio flash (though handheld and manually focused) with my contax and a P30+, at 200 iso.



What isn't typical medium format is this, shot hand held with the contax at 60th of a second f2.8 using window light and soft card fill and it was a very dark day in NY.
p21+ at 400 iso (pushed in curves about 2.3 stop) and the post work was very minimal



I've done this type of shot 30 times and it doesn't miss a beat, even if I go to 800 iso which doesn't worry me in the least.

The thing is Phase makes equipment, maybe too good, as with this new release and prior to that the other products I saw no reason to make a change.  

For one I love the Contax and my p backs.  They're like war zone solid.  I just bought the S2 to use my contax lenses and love the camera, but in doing a quick test last night, it makes me aware of how good the contax is and with the older phase backs t how much they offer compared to a lot of medium format that's available today.  

But these are my favorite still cameras I use today and they're way different.



Everything on that table costs equal to the price of the new phase back (if buying today).

The most advanced is the olympus as you can shoot a print ad and a broadcast commercial with it, if you know how to do post.   The viewfinder makes everything else I've tried look tiny and then there is the costs.  It costs less than 1/2 of the sales tax on the new phase back, so for 35 large
there really needs to be serious innovation, because the phase back costs more than one of my RED's.

I always say buy a camera if you emotionally want it (like a lecia) or if it will allow you to do something other cameras don't, (the olympus and the Contax).

But for another stop of iso and what I perceive (from the recent samples shown) I'm a little bit of loss as to what the new phase backs offers.

Maybe they'll surprise us with better samples, but if I was a dealer I'd be all over Phase's marketing department for the imagery they are pushing out with this introduction, because you shouldn't have to explain why it's not up to professional levels.

The one trend I picked up from the samples Phase featured, was everyone seems to have some kind of blog or link on their site pushing the new back.  The wedding girl has marginal samples and glowing remarks, the bicycle guy even has a link that says contact for a test drive.

Then there are all these quotes throughout the media (web media)  of can't wait to test drive this baby, or I'm sure we'll be shooting with a billion millimeter lens hand held.  

This is all just non verified marketing at a not very flattering level.

If Phase want's to dismiss the ccd vs. cmos thing, shoot something worthwhile with both a ccd and cmos camera.

But Doug, your quote that people that use low iso are only shooting product on white in studio is far from fact.  I've been shooting every camera I own in every situation possible for a long time and I'm sure i'm not alone.







IMO

"The thing is Phase makes equipment, maybe too good, as with this new release and prior to that the other products I saw no reason to make a change.  "

This is a big problem for phase/leaf/HBlad in the U.K*(and maybe elsewhere) in that there isn't much churn with owners wanting to upgrade, for a lot of working photographers once they had a 40-50mp (22-30 if fashion/editorial) back they just stuck with it as they don't exactly wear out and that's a big enough file for most uses.
I don't know anyone who has bothered to upgrade beyond that level and most have invested in things like blackmagic cinema cameras or canon C100/300 (not RED that's for the yanks) as paying £1000's for a few extra mp generates zero extra income.

*from somebody in the business of selling digital backs

I guess they will try to make as much money as possible before all the other players dilute the market and prices have to go down a bit like they do for most cameras over their shelf life.

"big problem" for who? …if they don't "upgrade" it's obviously because they see no "upgrade". Pros don't value "upgrade" with MP count… they value it with improving the presentation of their work… Take my case for instance, I use Contax 645 with all its lenses but the 350 and an Imacon 528c MFDB which does 16x MS (microstep) on a daily basis and beautiful single-shot too… I also use Fuji GX680 (with Contax plate on it) with 5 lenses and a D800E as well as a D4… Upgrade to what?

You don't know anyone who has upgraded from 40 megapixels to 60 or 80 megapixels? That doesn't really mean anything other than you don't know who they are.

What protects Phase One somewhat from the syndrome you describe (products too good, no compelling business reason to upgrade) - and why I don't subscribe to that viewpoint - is that their target market can easily afford to upgrade whether there are compelling business advantages or not, and frequently do.

at 1/10s, there is NO shutter shake.
so true... @ 1/10 you might get tripod shake, but shutter shake is @ shorter exposures... it dies too quickly (it is not a continued vibration) to show any effect for 1/10 exposure...  you need to see what is it around 1/60-1/100 probably

 ??? I definitely did not say that. Here is the quote you're referring to.

Quote
For some people the improvements in the IQ250 vs the 140 wouldn't be worth $500 (e.g. they shoot fixed-camera, fixed focus, product shots on white at base ISO in studio). For others they'd be worth it at twice the price.

I was simply point out two ends of the spectrum of needs/use. SOME shooters fall into the one end (only need low ISO, only shoot in studio) and others fall at the other end of the spectrum.

Great pics btw.

J,

Phase are now marketing themselves as Ferrari. They're turning themselves into a luxury brand for people with unlimited money.

Before the IQ 250 came out, I didn't quite realize that the Leica S is now a value proposition, but I guess Leica still think of themselves as Mercedes.

That's one of the exciting things about the sony A7 that replaced my digital back, mirror lock is no longer needed since it has an electronic first shutter. Hopefully one day that tech will make it to medium format.

Hi,

We sort of presume that mirror lock up is used for any serious photography. But shutter vibration is not eliminated so easily.

No I don't personally know any that have upgraded beyond that level but I don't work/socialise with rich amateurs or art market types who indulge (I did some work with a well known artist last year but phase gave them a back for the kudos) and obviously the target market for phase isn't working Ad/design photographers, some people upgrade as I see the backs on the shelves of the dealers but clients are not often demanding an extra 20mp and from a business point of view there is little reason to upgrade. clients pay for imagery not an equipment list.
I'm sure the IQ250 will sell as it offers more than just the usual mpixel bump.
I believe churn is an issue as I see it myself and the source of the comment was high enough up the chain. But it's obviously not reflected in all markets.

Vibration from shutter is always the same no matter what the shutter speed is, all mirror, shutter curtains speed and shutter phase change are constant speed actions.

I feel that the target market for Phase One is as much an economic target market than a specific type of user. From that standpoint, they create products for all sorts of users who can afford them. Naturally working Ad/Design photographers that can afford the product who make the purchase based more on what is best or needed for their business will be in the minority, though not entirely excluded. I do agree that "churn" is always a concern, what I see is that it has not been an issue in recent years. Phase One has been successful in confronting it. It's an issue for all manufacturers of photographic equipment.

But also I believe the pace at which users upgrade to the newest models is somewhat cyclical and somewhat dependent on the features offered vs the previous generation. IQ1 series was a smash hit, but it had the double impact of users who had held off on the P65+ upgrade from P45+ and older, and also from the pent up demand for the features it offered. The IQ250 is just one model and part of the IQ2 series, though it represents a departure in terms of features and therefore target market (from a usage standpoint).

Vibration from shutter is always the same no matter what the shutter speed is, all mirror, shutter curtains speed and shutter phase change are constant speed actions.
no dear, shutter impact is not like this (and it is not about constant speed of shutter blade/s/ during exposure - it is about the impact of the blade when it comes to stop for example, more so in mirrorless camera's operation, when there no things that can lessen the number of impacts/delay between those like electronic first curtain and/or small delay before the start of actual exposure, after LV feed ceased and camera's body is light /and in some cases IBIS/OIS is not ideal and might be affected too - that is not A7r case, but it is in m43 cameras for example/ )... it is not a continued vibration more so... it affects only a certain range of exposure times and 1/10 is not in this range... because exposure during the time frame when blur is caused by shutter blade(s) impact is way less than the rest of exposure time... so you simply will not see it with longer exposures like 1/10.

Have a safe trip back and rest well, Doug. Thanks for answering all the questions patiently for what were wee hours for us here in South East Asia :)
p.s. Next time you're in this part of the world, do drop by here in Singapore. A round of drinks awaits you and it's on me.

Likewise when you're next in NYC, Synn!

I guess you did not read my post fully, I said I tested from 1/10 to 1/800. The sequence was 1/10,  1/25, 1/50, 1/100, 1/250, 1/400 and finally 1/800. No shutter shake at any speed. I also did random numbers in between, e.g. 1/30, 1/40, 1/60 etc.

I read this "Well, I tested my A7R on a tripod in my backyard in 'field conditions' using a 600mm Mk II Canon lens with the metabones adapter. At f4 (wide open), at 1/10s, there is NO shutter shake. Sure the image gets a bit sharper at f5.6 1/800 sec, but you would expect that."... I am not sure why use BOLD letters proclaiming absence of shutter induced shake @ 1/10s :-) whereas everybody knows that it is not the shutter speed to test for it (if you want to isolate its effects and not other efects like when you have a really bad tripod/head/whatever)... as for your testing @ faster 1/10 you indeed write = "I found nothing from 1/10 to 1/800 that would suggest shutter shock.", but that's another story, which in liew of your special accent on 1/10 exposure speed does not add any confidence in you as a tester, sorry... now reread how testing was done by Lumo and repeat (pay attention to the whole mass of camera/lens combo too - you might want to repeat it w/ FE lenses or so... I am getting way less shutter shake when I am using E-M1 with battery grip and P35-100/2.8 vs E-M1 alone with P20/1.7 and with the E-M1/P20/1.7 combo I am getting it in 1/100-1/200 shutter speed range... )
