A few years ago I helped a friend do a science project regarding pinhole
size. We photographed a pattern of lines with pinholes taped over a 35mm
camera body, and the smaller than optimal pinhole did produce less sharp
images than those produced with the optimal pinhole size. The experiment
was not set up accurately enough to measure how unsharp the images were or
how much sharpness decreased, but the sharpness degradation was obvious in
4x6 prints.
