Of course, anyone who is serious about image quality isn't fooling with the little bitty pieces of film the Leica takes anyway. I've never been happy with image quality in prints larger than say 10"x15" from 35, and prefer 8"x12" as a max. enlargement. This includes images from the Leicas I had. It's not about sharpness but tonality, after a certain degree of enlargement the smoothness goes away.
I believe the quality of a print and the quality of its content are two distinct and separate matters. Confusing these clouds a lot of discussions.
I photograph things to see what things look like photographed.
