The thing that held me back from getting or making a pinhole camera is the lack of sharpness. Most of the pinhole pics I've seen are just soft. I know that's part of the appeal but it's a level of softness that I think detracts from most images rather than enhances them. I'm not a Leica-type stickler for sharpness -I use a 1924 lens from a folding camera on my Rollei SL66 - but there surely has to be a minimum level of sharpness. Is a 10x8 pinhole camera likely to provide greater sharpness than smaller formats and, if so, what is it equivalent to? How would it compare to, say, a 400 ISO 35mm negative enlarged to 10x8?
