Diffraction happens when light bends around a sharp edge at a steep angle, like when the aperture is set to a small size. You mean refraction? As far as it goes, 120 film can be "sharper" because the film base is smaller, I haven't seen anything to say one way or the other, so I'll take your word for it. BUT, MF lenses aren't as sharp as 35mm lenses, because they don't have to be. Maybe Zeiss and Schneider lenses are, but you're wasting contrast to have such high resolution with the enlargements that are going to happen. -- Eric Welch Grants Pass, OR
