I have a question because I read the MF thread a lot, but I don't usually post, since I don't own one and they seem to be a completely different world. Still, I am drawn to MF, and maybe because I am shooting more people these days and less of other things, and MF is suppose to be "the thing" for people type photography of this sort.
So in a very simplified way, what would be the visual difference between these shots if they were taken side by side with a 1DS3 using the same type of lighting, given correct exposures for both cameras?
Thanks

To only speak to my work, not much difference, but that depends on the subject, the lens, the workflow, the expectations.
This is an approx. crop of the different formats
It would make you think that the difference in format size is 200% and in some instances, viewing one to one on a monitor you can lean back, light up a cigar and feel pretty good about your medium format purchase.
Then those moments pass and you have that day when you start viewing this as a client. When you select for your website, an awards ceremony, a print showing, then you don't look 1 to 1 you look for "the shot".
At that point the shot is all that matters and just like a client , you probably won't care if the pants stitching has 25% more detail, but you will notice if you missed the smile, or didn't catch the emotion.
You also have to remember that medium format is not true medium format anymore. It's at best close to a 645 frame which from the film days was the smallest of the medium formats though we are still working off legacy lens sizes which don't always translate well to cropped frames.
This would be different if the sensor sizes were 6x7 or even full frame 645 and the lenses were faster and more comprehensive. F 2.0's, tilt shifts in all multiple formats would make the almost 645 digital formats more useable, but once again, we are still working from legacy film sizes, with new digital formats.
Where I see a difference in the "look" of medium format vs. a Canon dslr is less in the format and more in the overall sharpness from Canon's agressive AA filter.
The Leica M-8 has no filter and gives a sharper look, though not really a more detailed image if that makes any sense.

Still, that doesn't mean that medium format doesn't have a place as in my work the main reason I use it is for it's ability to tether, though overall in the final look of the photograph, there is not that much difference between a cropped 645 and a full frame 35mm.
Others will see this differently.
