If you want to see sharpness, have a look at a 5x4, 6x6, 6x7, 6x17 or 8x10 image from a traditional camera; any one of which could be enlarged to 81cm+++, or to the limit of the enlarger/printer — and 35mm really doesn't count when you are serious about being s h a r p. But when talking about pinhole cameras — and these cameras in all their simplicity and lack of refinement, have a beauty that is all their own, don't compare the results with those from modern cameras; the ancient scripture of pinhole photography doesn't need the negativity: it's been proven since Da Vinci's time.
