A new high-end Sinar digital back will take the place of the actual eVolution 75H multishoot. With more pixels. But with or without screen ? And working with an iPad who can give an high-end live video ?

a 5x4 Foveon-type chip made by Contax and licensed to Holga for use in their new high iso (1,024,000), 76 fps, $99 plastic rangefinder. The latter will also sport a new 5x4, 16-bit, 960M LED display.
Initially it'll only be sold in the Outer Hebrides islands but a company spokesman has indicated that as production ramps up and depending to customers' feedback, it will consider expanding the business into a few other small island groups in the South Pacific.

This is fun:)
How about
- a direct image virtualization technology with scalable output architecture from a developed film negative to 24" print, including real-time replication and off-site backup solution to up to 5 continents.
- Camera bodies available in either 4, 8 and 12 core configuration.
- Nuclear-powered batteries with upto 35 years charge and minimal explosive hazard.
- Capability to share power with local appliences when not in use.
-
Staying strictly within the realm of the technologically possible (in 2010)... :)
I'd like to see a new P+ back from PhaseOne using the Kodak KAF-40000 (the same chip in the Pentax 645D and Hasselblad H4D-40). This is the highest performance-per-pixel MFD sensor around at the moment (highest q.e., joint lowest readnoise, joint lowest dark current). Forget your P40+ and P65+, which like all DALSA MF CCDs, have poor dark current (hence the 1 minute exposure limit).

I can imagine that Phase & Leaf will introduce Capture One's focus mask in the firmware of their backs ... or any kind of image-based focus confirmation (as sensor based live-view prior to the actual capture is not possible). Maybe also on board JPG conversion...
I also expect the Super Digitar 28mm to be ready at Photokina...

I am for all of these, especially the nuclear batteries; hell they've been in satellites for years.
I think it would also be cool to incorporates Leaf's revolving sensor into all of Phase's backs.

This is not too far from a design I have been thinking up...not out of your eye, but...
You end up wearing a partial helmet like device that has a loop eye piece that flips down in front that records and captures stills (if that will make any difference) using nerve reseptors to know where your eye is focusing, so the lens reacts with your eye. The visual is imaged using optics to reflect, and transfer to a large MF sensor on the back of the unit on your head. Canon will have the MF chip but license to differnt makers of differnt style head cams, Porsche Design will have a carbon fibre model encasing the inards. Luois Vuitton will have a leather version, while Chanel a micro thin ceramic version. A stereo model will follow and be able to record 3D video.
-
I hope phaseone is working on leafshutter lenses. Perhaps we will see a new line of all leaf shutter lenses, of course it will be just in photographs, or more likely a beautiful 3D rendering like the red cameras. This is a never ending story, i'd like to not worry about what is going to be announced and not sold in the next months

Indeed interesting and I expect better information from Pdf as well. A more than 33MP multishot back is interesting. The only current ones with higher rez. are the 39 and 50. I pretty much rule out the 39, the 50 being a Kodak is possible but it would be nice if they got the 60Mp Dalsa in a ms form. The instant king of IQ :)
We'll see.

There is a 48 megapixel Dalsa sensor that no one uses: http://www.luminous-landscape.com/forum/index.php?topic=30447.msg245384#msg245384 (http://www.luminous-landscape.com/forum/index.php?topic=30447.msg245384#msg245384)
I don't know if it's possible to fit the mechanics for a multishot back AND a screen, battery and CF card all inside the back housing. I can't imagine any new back will have it all - something won't be there. Doesn't the Hassy 50mpx have no internal battery?
Ben

I have a 39MP multishot back that has it all. The battery is underneath the back though but you normally would not be using that in multishot mode. Both the battery as well as the screen would primarily be used in single shot untethered mode.
A while ago that 48MP Dalsa sensor. I recall it having microlenses? My strongest guess would be the 50MP Kodak if this rumor is true but it would be nice if Sinar came with a pleasant surprise.
The Hblad50 gets its juice from the battery grip (or from another external device when used on something else than its dedicated H body).

Add me to the list of people very curious about this rumour!

I don't know what will happen in medium format land at photokina but I would suggest whatever is announced to have it ready to buy the day the pdf hits the airwaves.
I know in the world of marketing it's tempting to say something is coming to hold buyers attention or to keep them from moving to another brand, but from a professional standpoint, unless you can buy it, rent it, use it that day, it really doesn't exist.
As far as MY wish list, well top of the list would be a good Nikon style LCD, but I don't hold much hope for that, though I'd forego the lcd wish if the makers would just make all of their backs easily interchangeable with all medium format cameras.
I really believe the limiting of the medium format market happened the day that each maker decided to make specific mounts for specific cameras. (I know hasselblad and Sinar offered something interchangeable, but they both required screwing and unscrewing stuff, and the backs seemed to come at a premium).
I'm talking about just click it on and shoot. I know if my two back would fit on any body I'd have an H-1/2 sitting in our studios to compliment the Contax's I use.
I'm really not a fan of proprietary film digital or analog and I believe one of the limiting factors of medium format (beyond price) is the fact your stuck into one system at the time of purchase, (without buying the value added, floor mats not included warranty) and even with the switch em for free warranty your still not going to be able to snap that blad back on a contax, or the phase/Mamiya./Leaf back onto a Rollei.
I also suggest a 3 year bumper to bumper warranty and ending the $2,500 watch battery repair thing.

Please educate someone not familiar with view cameras, why is 1/250th a cutting edge huge deal? In other formats that sounds rather slow. I'd love to understand why.

I'm sure there is a reasonable explanation why only 1/250 .. but Copal 0 shutters are 1/500th , so youd think they'd be able to at least match those.
-
The stability of the assembly with an electronic shutter is sharply better than any one with classic central shutter. The fact of having to rearm mechanically gives a real risk of moved. It is from then on impossible to practise the multishot, or to realize multiple digital images for assemblies under Photoshop.
I work for years with an electronic shutter Sinarcam 2, for my biggest happiness. My objectives equipped with mechanical shutter take out their cupboard only for ballads to the open air!

Is this the only use of this chip in a Db and if so why ? Exclusivity deal ? The tech sheet says its only 14 bits per channel, but a signal:noise of 74 Db is I believe up there with the P65+ sensor if not better and hence a little bit ahead of the others in terms of dynamic range, maybe to do with these "special micro lenses", not sure why they are special. Anyway, I guess this back is the only one with this chip, which i am guessing has a 1.1X crop factor, so in fact at the moment there is no stand-alone version, just this tethered studio version ?
-

{B} The tech sheet says its only 14 bits per channel, but a signal:noise of 74 Db is I believe up there with the P65+ sensor if not better and hence a little bit ahead of the others in terms of dynamic range
{C} maybe to do with these "special micro lenses", not sure why they are special.
{A} Dalsa has taken two years to find a customer, so I doubt it is an exclusivity deal!
{B} As you say, the DR is good, which should illustrate the fallacy of "16 bits is better than 14". 14 bits, or even 13, is more than enough to handle the DR of any MF sensor seen so far, so the difference between 14 and 16 is at best just a decision to pad the data out to fill two full bytes, and at worst a marketing ploy.
{C} What is special about these micro-lenses is that they are placed closer to the photosites than previous ones, and so avoid a problem of all previous micro-lenses: not capturing light that strikes the sensor at highly off-perpendicular angles (over about 20-25º), so that they would lose a significant amount the light from some MF lenses near the corners of the full 645 format frame. For that reason, micro-lenses had only previously been used on smaller 44x33mm sensors, which do not gather any light from near the corners of the 645 frame anyway! The new design allows using micro-lenses on a larger (48x36mm) sensor than before. That increases sensitivity (higher usable ISO), but not DR. The DR improvement is due to having larger well capacity that Kodak sensors of the same pixel pitch and maybr lower read noise two.

Sorry everyone, I misread the data sheet, it is a 16bits/ch back like most others.
I asked sinar if an eMotion 86L will appear soon alongside this evolution 86H, but they they couldn't confirm it, they wouldn't deny it either. I like the fact sinar backs have some built in memory and have heard teh iso 800 is pretty good. Despite the microlenses, the "new" chip doesn't do iso 1600 like the P30+ does for example... strange.
-
... have heard the iso 800 is pretty good. Despite the microlenses, the "new" chip doesn't do iso 1600 like the P30+ does for example... strange.
The maximum ISO is partly a back maker's decision about which amplification options to include. I have never seen a maximum ISO in any MF sensor spec sheets, and I suppose that all MF backs could offer an ISO 12,800 setting (with huge gobs of noise) if there were a market for it. Since this back is aimed at studio work and multi-shot, and thus stationary subjects, offering one extra, noisy, high ISO level seems a low priority.

Still, this is exciting news. Finally a quality TS lens for the M645, and if commercially successful I'm sure they will bring out more focal lengths.

Hoping there will be Phase One branded 50mm and 90mm.

Judging by the optical cutaway diagrams, there isn't enough spare backfocus to re-engineer the 50mm and 90mm to mount on a 645 camera. Remove the tilt mechanism and maybe they just would fit, as a shift-only lens, but then I suspect that the image circle would greatly reduce the available shift on 645. Not worth the candle, really.
The 120mm on the other hand is a nice surprise. Never thought I'd see the classic Symmar design in a lens for a Mamiya 645! Fantastic.

Phase has some interesting stuff coming down the pipeline, if the hints and winks at the recent event in Iceland are any indication. That said, Photokina is not regarded as nearly as big a deal as it once was, so the announcements aren't being built around the event any longer.
In Iceland we got to test the 150 LS lens, and the battery grip. I think I detected a hint that a new 300 is coming - probably next year. The biggest deal to me, and comments I found most interesting is that the tech people at Phase see their current 645DF body as being pretty much maxed out in it's current form, and the next iteration - which they are working toward - will be substantially different. But for that, I think we'll probably be waiting a couple years to play out.
As a personal guess I would say next year will see a P85+ come out.

Probably, I am just wondering how many people are really waiting for that...
-
Going to P85+ from P45+ would probably make more sense than going from P45+ to P65+. Well, as long as a new back introduces something big which is currently missing and the list of big things missing on these expensive backs is quite a long one. Not to mention constant progress in DSLRs functionality, which defines the standards for the whole industry..
-

it would be quite appealing to me if it had senor plus 20+ mp setting along with a very very large files for different options. my retouchers still prefer the largest files i can supply- it makes compositing easier.

What is the need for [more] leaf shutter lenses if the DF body with appropriate digital back is capable of syncing at 1/1600th?
-

This is a great question. If the max sync on the LS lenses is 1/800th, but with a P40/P65+ can go to 1/1600th, logic might dictate that you don't really need LS lenses to achieve this sync speed..... unless a LS shutter is necessary due to the circular shutter action vs. a vertically moving slit opening of a FP shutter.

A variety of timing techniques and technology are used to accomplish 1/1600th sync with full flash power. This requires both a leaf shutter and a DF body with a P40+ or P65+ or Aptus-II digital back (and presumably future digital backs). With other digital backs the advanced timing techniques cannot be used and so the flash sync speed is limited to 1/800th.
The exciting part is the built in flash sync which will include 1/1600th sync that is built into the DF V-Grip Air. I can't wait to test this as there are very few (read: I can't find any) wireless options that can handle wireless sync with studios strobes at 1/800th (without losing light), let alone 1/1600th.

Thanks for the input, Doug.
If the max speed on the LS lens is 1/800th, is the 1/1600th speed "real"? In other words, is there a one stop difference in exposure between an ambient-only (no strobe) shot at 1/800 @f/5.5, ISO 100 and one taken at 1/1600 @ f/5.6, ISO 100 (when using this speed on the LS lens only)? Presumably, if the focal plane shutter is not being used, then the speed difference mush be achieved in a shutter-less fashion on the CCD, similar to an interline CCD used in broadcast video cameras. Or, is the 1/1600th speed achieved using both the LS and FP in concert (LS for flash sync, FP for ambient during the LS exposure)?
Any thoughts?

Altough this is impressive technology that might be useful in extreme situations, we´ve had this before: studio strobes (including the fastest packs like Pro8 or Bron Scoro) set to an average power from lets assume about 800Ws will have a longer flash duration than 1/1600s, so you loose a lot of the light emitted by simply cutting the time.
I really miss the smaller companies that used to be at Photokina years ago, feels a lot more of them disappear every two years...
Cheers, Ulf
-
Well to be fair, even though 'other brands' like Elinchrom combined with Hasselblad may not sync without the loss of some light, the amount of light lost is less than a stop and that's like putting a diffuser fabric on many boxes.
So it's not a huge deal, unless you are trying to pull all 1100ws or 2400ws out of a pack and need every last bit.

Exactly.
We shoot a lot of frozen moments with people and nothing freezes an image like a short flash duration and nothing gives you a short duration like cutting the power.
What really is needed is 400 to 800 iso very clean and then you can run most packs or monoblocs at lower power and freeze it solid and unless you have a lot of ambient light kicking around, the flash sync is irrelevant.

It depends on how you work, but I don't think I've ever been in a situation where flash was involved and we needed to freeze a moment that we hadn't planned on limiting the ambient light anyway.
How many people that buy a $30,000, to $40,000 camera don't come prepared for their creative brief?
It's kind of a double edged sword. You can raise the power and get longer durations and I guess with your system sync at 1/1600th but overall your still cutting into the flash, or just lower the power and get a shorter flash duration which probably works out about even.
Or you can buy the new profoto 8's though they have a very heavy draw from the mains and cost more than a space shot. Actually I think most of the pro 8 use is from rentals.
Regardless, it's nice that phase has upped the sync under certain situations, but a bigger innovation would be clean higher iso, as that covers a lot more territory and is much more economical for the whole production.
When it comes to buying and/or renting and how it impacts the production, there is "want" and there is "must have". To freeze action with flash "must have" is a short duration.
We all like new equipment, we all like fun stuff, but now, well it has it fall into the must have category to open a wallet.

in this case I´d prefer 25ASA...
-
... and nothing gives you a short duration like cutting the power.
I'm not sure I buy this statement. It is certainly true that cutting power to flashes using IGBT circuits will shorten the duration, but I think it is not true of "normal" studio strobes.

It's true of the Profoto Acute, Acute-B, D4, Compacts, Pro-7, Pro-8 for sure.
Don't know as much about other brand's flash durations.
-

Lower ISO sure helps in some cases. Of course at lower ISO you need more power to your packs forany given aperture. Which if you're trying to do very fast freezing of motion then requires you to turn up your pack power (or add additional packs or move the light closer etc) which increases flash duration.
Best option [bias alert!] is to have a back/body/light/transmitter system that has a wide range of sub-ISO-100 options (which aren't fake settings like Canon's ISO50) with a leaf shutter system that allows down to 1/1600th sync without losing light. Then you can do just about anything. Like any of the Aptus-II line and the P40+ / P65+ on a DF body.

Actually I never spoke of freezing motion, I would try to get rid of the ambient light with the shutter speed. Extreme short exposure times will limit the use of strobes if a bit of power is needed. It might be nice to have, but I´ll second BC, absolutely no must have, I am sure, until now I have never used a shorter shutter speed than 1/320s with my H series Blad. Freezing motion with strobes is achieved using short flash duration.
Regarding shorter flash duration when dialing down power, a rule of thumb could be, if your strobe is color corrected within its power range it will have shorter flash duration with less power. You don´t necessarily need an IGBT controlled flash cut off (Broncolor Scoro and Grafit) for that, the other way is not using all of the capacitors (Profoto and others) "Old classical" designs with 3 or 4 stops of variation will also vary in color temp and even tend to have a longer flash duration at lower power. As a photographer it is good to know your equipment and its limits.
Curious what I might discover this time at Kina...
Cheers, Ulf

Freezing motion with strobes is achieved by BOTH
- using short flash duration to expose subject sharply
- reducing ambient light exposure enough to avoid ghosting
Of course in a studio you can "reduce ambient light exposure" by turning the lights off (or far down relative to your shooting aperture/ISO). Outdoors you can only "reduce ambient light exposure" by lowering camera ISO, stopping down, or reducing shutter speed.
Trust me I'm not saying many shots at all would require 1/1600 sync speed - we've lived with 1/400-1/800 for a while. But I'm sure we can all agree that raising a technical limitation like that reduces the chance that your creative intention will be limited by a camera specification.

Great they have built-in tripod mounts.
exactly - and you know what this means: you can lock the lens, and the shifting movement will move the body. so... you can stitch perfectly!
It's a very simple lens design - just 6 elements, so shouldn't be SO expensive. ha ha.

Doug,
I see what you mean, and of course you are right. What I originally tried to say is: Be prepared that if you use a (slow) strobe and you would need for example 1600Ws to light your subject to achieve the desired aperture the use of the fast shutter speed will cut your flash and the whole system might not perform the way you intended.
Regardless, this is an impressive technology and might be helpful for some situations. Believe me, I am more than happy to be able to use the advanced features of todays cameras and lighting equipment, they are pushing boundaries to a complete different level. But still, you have to know their limitations ;)
Cheers, Ulf

Maybe you fellas can create a new topic post for this.

As I recall Adrew Zuckerman's 'frozen' shots (the water baloon, milk, etc) were shot with a hasselblad, 1/800. These were sharp, no smudging / smoothness caused by motion. I wonder what 1/1600 could be used for..
overkill?

these shots wouldn't have had ambient light as a factor (ie over powered or just a dark room). so shutter doesnt matter as it only controls ambient.

News from Alpa :
NEW CAMERAS & ACCESSORIES
ALPA 12 STC
The all new ALPA 12 STC (Stitching/Shift Travel Compact) is the youngest member of the ALPA 12 family. It will set the benchmark for compact technical cameras - especially in the class of truly handheldable technical cameras not only for tripod use. The ALPA 12 STC is of course prepared for digital use (digital backs of up to 60 MP at the moment) and with some rollfilm backs up to 6x9.
The ALPA 12 STC allows the travelling photographer free hand operation as well as fast, convenient and reliable stitching and shifting (geared and free-wheeling) on tripod. As all other ALPA 12 models the STC is completely integrated in the modular and extensive ALPA 12 platform. All movements got realised with roller-bearings - not the cheapest but defintively the most precise, stable and long lasting way.
ALPA Sync Release
All digital backs need a synchronisation between the shutter and the back. In addition some Phase One and Hasselblad devices need a "wake-up" signal before the exposure. ALPA offers with the ALPA Sync Release a large and unique selection of synchronisation solutions - for the first time really optimal for tripod and freehand use.
ALPA HPF High Precision Focusing Rings
Certain photographic applications need an extremely differentiated scale focusing - e.g. when using a laser distance meter. ALPA offers with the ALPA HPF rings a unique and retrofittable solution for these requirements which is - in contrast to other offerings - truly usable in freehand operation.
ALPA iPhone® holder
The new ALPA iPhone® holder allows the technophile photographers using their iPhone® 3/4 and iPod touch® (later also others) a secure and firm mounting of their device on top of an ALPA. Four positions are available:
horizontal, symmetric
horizontal, minimum prallax
vertical, symmetric
vertical, minimum parallax
Possible applications are...
electronic viewfinder (ALPA recommends apps like "Viewefinde Pro" or "ProCamera")
as GPS logger
as control unit for electronical shutters and the like
as digitale notepad
other apps are under development
ALPA Lens Corrector (reloaded)
ALPA will release new distortion correction profiles of over 90 third party lenses/focal lengths for the all free ALPA Lens Corrector. This Photoshop® plug-in allows the distortion correction at it's best including movements. Why for free? Just because we love what we are doing! With first priority there will be an update containing the new ALPA lenses from Rodenstock and Schneider-Kreuznach and the most common digital backs plus various lenses of 3rd party manufacturers for dSLRs and Micro 4/3 cameras.
The iPod touch/Phone/Pad seem to be the new indispensable object to the photographers!

Yes in fact I did a series like that with medium format film with a shutter speed of 8" so that I could manually trigger the flash during the exposure. However, this only works if you can control the ambient light (e.g. turn off the modeling lights and room lights and block out the windows).
Try to freeze fast action during the day and shutter speed at which your flash will sync at full power becomes very important.

Thanks ... pity it does not hold an iPad, yet. But my vision of using an iPad and a black cloth to recreate the 8x10 view camera experience gets closer ...

And what do you say about the non-rotating rectangular sensor fixed back (CFV50) specifically made for a "square" camera?
They must be receiving so many negative vibes that they will all get sick at their headquarters.
