With respect, I don't think it's important how images look when reduced to tiny JPEGs. I'd want to see details at 100%, shadow noise, smoothness of graduations, etc
Graham, I agree that it is hard to see details in any web image since the resolution is limited. I'd be happy to make full resolution copies available to anyone who would like them, or even the RAW files if you wish to process for yourself.
Shadow noise is not visible in either camera, as I would expect shooting ISO 50 with both. The drawing signature of the two lenses is different, giving each a distinctive look. The Mamiya 80mm AF is a 2.8, where the Zeiss Contax 80mm is an f2. I shot some test frames wide open, others stopped down to f8 in both cases. My interest here is not necessarily which is sharper or really about the lens differences at all. I wanted simply to satisfy my own curiosity about the differences in each of these systems as a creative tool. Even at small size, the proof of the pudding is always does a particular tool give you a predictable result, that you can rely on shooting in the field and in your studio. In this case, from admittedly a very short time with the ZD, my opinion is that it is a fine camera system, taken as a whole. And so is the Contax system I've been shooting for several years now. Each has it's strengths, and each it's limitations.
What is important to me is the difference of the "look" in the two systems. I like having options with digital, just as I used different film stocks back in the good old days? Dating myself here I guess
Making beautiful images is a matter of learning the craft skills of photography, and training your eye to see as an artist. Both of these cameras are very capable of producing great results I am happy to say.
One of my greatest hesitations tromping around the wilds of Mexico these past seven years was the cost of the gear I was using, and how hard it was to get repairs when needed. As a result, I used 35mm for a lot of my field work, even when I was wanting a MF look. The ZD is priced low enough that I can afford to have two complete systems for backup, and without having to sacrifice my quality standards to a point that the end results are simply unacceptable for print & publication. No way that is going to happen with the Leaf. Or a Hasselcon. Or a Sinarback. The client work I shoot just does not pay enough to buy two of any of those three brands.
So for myself, there is no choice to make between these two. The choice is between buying into the ZD system, or going with yet another Canon or Nikon, at least until Leica gets it together with the R10 and I have a chance to shoot that. I love the MF & view camera look, and always have. And I readily admit to being a megapixel junkie, as I find it hard to always have exactly the right lens mounted all of the time, so there are times that I need to crop away the unwanted portions of the frame. That is where megapixels rule in digital. I can't count the number of times a client has decided to crop in even further, so having the resolution available is a great safety net.
I am impressed with the size, weight, and the quality of the ZD. I think it holds up well with the other brands 22 megapixel offerings. And at a price that I can at least live with, and not end up living in one of Guy's outhouses!
