Diffraction is a physical result of having a small hole, imperfections will
only modify the diffraction pattern. If you are concerned about
imperfections, why use a pinhole at all ?

Why would you spend that amount of money on a 50mm focal length pinhole
when
you can buy a good used 50mm f1.8 from Olympus Guy for the same price ?

Well, I guess you're right, we should all be using 50/1.8's. That would
make the world a much better place, right? i think I would use a pinhole
for a learning exercise, after all the first camera's made were pinholes. I
might use it for the incredible depth of field. I might use it for
something a bit different. I didn't think $20 was really a lot of money.
