I'm trying to decide between a 1DsII and a MF system for future fine art landscape work. I'd like to print up to 20 x 24 on a regular basis, and maybe 24 x 30 on an occasional basis. I've read and reread and reread again all of Michael's articles on MF vs other systems. I've scoured this forum. I've compared files shot by others. I've compared other people's prints. And I'm no closer to being able to make a decision. The claims and counter-claims are just too inconsistent, the files and prints I've looked at aren't of the same subjects and are therefore difficult to compare, and some people (Michael in particular) seem to keep changing their opinions. It's very frustrating.
For example: The P25 IQ is clearly better than the 1DsII and challenges 4 x 5 film. P25 and 1DsII prints are difficult to tell apart up to 13 x 19. The 1DsII IQ competes with the P25 using Zeiss lenses on a Contax 645 as long as you use the best Canon lenses and techniques. Zeiss lenses on a Contax 645 are limiting the P25 and suck compared to Schneider lenses on a Cambo. The Zeiss lenses aren't limiting the P25 after all. Zeiss and Mamiya and Hassy lenses are just fine even up to 39 MP and it's very difficult to see any difference between them. Michael, my apologies for singling you out above. I really appreciate all of the reporting you've done on MF systems, and I've learned a lot from your reports. I know you've been reporting in good faith what you saw at the time you reported it, and that as one gains experience with a system, assessments can evolve and change.
OK, now that I've vented, I have some simple questions for the forum (simple questions, but I'm sure not so simple answers). And yes, I know I should run my own tests. I've been promised a Rollei 6008 AF system with some Schneider glass and a Sinar back in the near future. And I'm trying to line up some time with a Mamiya system. But this stuff takes time. And yes, I know that the 1DsII will soon be replaced with something better. But right now, no-one who knows is talking, so I have to compare with what's available today. So, here are my questions:
With what size prints do the advantages of 22 MP MF backs vs the 1DsII become apparent? At what size do the MF advantages make the print more SALEABLE? Yes, I know there are a million variables, but assume everything else is equal, except for the system used. You get to choose the camera and lens and 22 MP back. Please take into account not only resolution, but also smoothness of tonal gradations and shadow detail. Assume a low ISO. All I'm looking for are your informed opinions. It doesn't have to hold up in a court of law :-) We all love to give our opinions, so now's your chance :-)
For prints up to 24 by 30, am I going to see any SALEABLE difference in IQ using a 33 MP or 39 MP back over using a 22 MP back? How about smaller prints - 16 x 20 and 20 x 24? Now the same question, but this time comparing 33 MP and 39 MP backs against a 1DsII.
Thanks in advance for your opinions,
Hans.
