My first camera built completely from scratch: naturally, it's a pinhole
The experience was useful, and will be used once I decide to finally make a wide angle (6x12?) camera built around the Caltar 65/8 lens I have… Well, one day, perhaps. Until then, it's pinhole for me: focal length 30mm, laser cut pinhole 200 microns. Should be fairly wide: I have yet to put a roll thorugh it - just finished it this evening.
