Interesting stuff. The A7rii should really be there, the D810 though, the res is a bit low for this test I reckon.

I suspect that the sony sensor will hold up exceptionally well under these conditions, and really show its true potential.If you shot the same rodies on a cambo Actus with A7RII the fight might be fairer.
No, it wouldn't be fun at all Guy................
Whats funny is today is the 15th the middle of the month and I'm paying those monthly bills right now but just imagine cutting a 50k check for this it would be fun but than on the other hand i would be carted off to jail for writing a bad check. Now that would not be fun. LOL

Agree with you though, this is a difficult test. However, it would be the first I am aware of where the same subject has been photographed with different systems for all to evaluate.
Clearly the MF will score high on resolution and the benefits thereof. But the interesting part, for me certainly, would be by how much? What is the difference in real world usage between a 100MP MF back and a 42MP 35mm back.
Mind you, I am not talking about value for money or costs at all. If money were no object would one still go out and buy the MF back? Because then you also have to consider all the accouterments that need to go with it. So as much as it is about getting the best image it is also about the hoops and loops one needs to go through to get there.
I can see this thread will be a long one.....:chug:
Guy, I love my Sony too, realizing I have not touched my Canon in over six months since there was no wildlife to shoot.Its not as great as one would think. Need to remember as well that you don't compare images in the real world . You shoot, you process and evaluate that single image not against anything else. Thats the real reality, is the MF overall better well sure it is going to be we all know that and why we buy them. But its not as great as some would think. I have done this test, never posted it but I certainly evaluated the differences and they are there but you better have a damn good eye to see it. Obviously detail is the huge plus for this back. so if you need it get in line to buy one. Im very neutral on all this , yea I have the Sony as my bulldog in the mix but thats what I need and happy as a can be with it. The cards just won't let me get back in MF but I did love it and it was fun. I am still a big cheerleader for MF and glad to see the progress but more important IT AIN"T DEAD. LOL
Thats a very interesting comparison on the film vs digital. Yes, film can produce higher resolution than digital. I don't think it included scan backs like the early Phase One or BetterLight systems, which I went to 1st from 4x5 and 8x10 film. The problem with film is and was always that it was very time consuming operation, to say nothing of how hard it is to find decent E6 labs and such nowadays.There have been several tests of film vs digital, like this one from on landscape: https://www.onlandscape.co.uk/2014/12/36-megapixels-vs-6x7-velvia/
which includes an IQ180 and the 36MP Sony sensor vs different film sizes and types.
8x10 is ofcourse still the highest resolution by quite a margin, even without the 'for the buck' part and that will stay that way. I hope some light will be shed by this test on how easy it is to get a workable file with good color from the various digital systems. Interpretation of the results can't be done by anyone else but the user based on their own requirements and he or she will want to have different variables tested which makes this an impossibly difficult test to conduct for a third party.
I would have thought the inclusion of the A7RII is essential. It is a class defining camera that uses very similar sensor technology as used in the new Phase One IQ3 100mp. I think its good enough to replace most digital MF, but is that a step too far? These very useful tests might determine that question. Also, no Hasselblad?
did I miss something? What was the camera/lens combo's tested for the digital backs?Cameras
- IQ3 50mp (previously we only had the Credo 40, Credo 50, IQ3 100mp, IQ3 80mp, IQ3
- Pentax 645Z DNGs with 55mm
- Pentax 645Z DNGs with 90 macro*
- Sony A7RII with 55mm Zeiss
- Sony A7RII with 24mm Zeiss
- Canon 5Ds R with 50/1.2
.
Helped by an equipment loan by Pradeep, we captured the following additions to the Massive Still Life Test on Friday after hours...
Cameras
- IQ3 50mp (previously we only had the Credo 40, Credo 50, IQ3 100mp, IQ3 80mp, IQ3
- Pentax 645Z DNGs with 55mm
- Pentax 645Z DNGs with 90 macro*
- Sony A7RII with 55mm Zeiss
- Sony A7RII with 24mm Zeiss
- Canon 5Ds R with 50/1.2
Tests completed:
- ISO sweep (even light)
- ISO sweep (contrasty light)
- Aperture sweep
I'll process and post these files early next week. We have a few more tests to complete Monday which will delay my ability to process, organize, and upload these files.
My apologies to anyone whose preferred camera was not included. There is no limit to the number of cameras, lenses, and variables I would have liked to test. We've worked some crazy hours since the release of the 100mp to do these tests while also keeping up with our normal day-to-day work. If you were hoping for a different camera or lens... Digital Transitions is always glad to host any test at our facilities in NYC and LA; we have an extensive range of Phase/Leaf gear, basic studio amenities (lighting, modifiers, stands, tripods, and computers) and are glad to have you bring whatever gear you'd like to make any comparison you'd like.
*The test set was based on a normal-length lens and the column on the copy stand used was not tall enough to reproduce identical framing with this longer-than-normal lens so it was cropped in a bit. We included it despite the tighter crop giving the Pentax an artificial advantage regarding resolution.

I don't really see how that will affect the outcome of this test.I'm surprised that the 50 1.2L was used for the Canon. If has known focus drift.
