But if I look at the middle portion of a 35mm tranny shot at f22
(approximating to the area covered by the small sensor), I do not see all

digicam?



Perhaps due to the resolving power of 35mm film? The small sensors in most digital cameras will produce soft results at very small apertures due to diffraction. Same reason you don't find F64 on lenses for 35mm format.
