Hi: I'm not sure yet. It all depends on what I decide to be the smallest field of view that I want. Depends on how small I want to shoot.
A short focal length /wide angle would give me a wider field of view, which would be convenient for just setting the camera on top of something and taking a picture. But it limits how small I can shoot. The longer the focal length the smaller the field of view and the smaller the object I can photograph. Hmmm Maybe I should try making a variable focal length camera, with a viewing pihole and a taking pinhole, and a ground glass. But thats starting to look like a lens camera. I think a normal focal length ~ 12" as a compromise. If I like what it does I can make a short or long one as well.
