There are also pinhole boards with interchangeable pinhole inserts available for Sinar, Graflex, Copal 0/1 and 3 adapters and other cameras in our other listings.

Blank, custom size hole and Leica Thread Mount boards are slightly more expensive since they require more time to produce.
3D printing process produces dimensionally accurate objects but slight surface imperfections/scuffs can be visible from the process.
Please take a look at the pictures. They were taken with flash and surface variations and small specs of dust are far more visible than in real life.
Lenses mounted on the camera give you more realistic look.

Other not listed combinations of lens boards possible. Combined shipping available with other listings.
