Thanks Marc, that's actually more than I expected. I hesitate in writing, because I don't know exactly where I'm going from here. I've owned V equipment since 1972 (all CF lenses to day). While I've been shooting 35mm digital since 2001, I'd like to make the transition to medium format digital. My preference would be square, but as your CFV 1.5 post indicates, there are too many negative concerns with owning the CFV back. But if I could swing an H2 body, and maybe the 22mp back, and make use of my current CF lenses, I'd be a little ahead of the game for a while, even though I'd have to shoot rectangle.
My concerns and issues would all go away if there were a larger square format back available for the 500 series bodies - larger in image size and file size. I don't even care if it's not a full size, but something better than a 1.5 lens factor (even 1.1 or 1.2 would make wide angle shooting a little easier. And a 22 mp square back would be all the resolution I need. I print with an Epson 7600, so the largest square I can produce is 24x24". And as long as I can tweek out 180 ppi @ 24x24 with no res&ling, I'm a happy c&er.
BTW - the current 16mp back yields only 170 ppi @ 24x24 - and that's using 100% of the image area, leaving no room for even a slight crop.
