"Chuck" you need to go to My Controls and change your Display Name to a real first and last name, as per the forum requirements listed when you registered.

Also, why is this posted in the Arri D20 subforum?

C-mount was originally designed for 16mm when it was a home movie format. It consists of a simple screw thread, nominally 1" outside diameter, and 32 threads per inch. That's a National Fine standard, you can buy taps and dies for it from any machine shop supply place. The flange - focal distance for C-mount is 0.690", and most lenses will have threads extending about 0.150 - 0.160" deeper into the camera. That leaves you just over half an inch between the end of the one inch cylinder and the film. Most mounts for 35mm, to which the D-20 was dimensioned, are quite a bit deeper, typically near a couple inches. That makes the adapter the OP wants quite difficult to make. It's typically easier to adapt 35mm lenses to C-mount cameras. They're also sure to cover the whole 16mm frame.

Be careful if you make or rent an adapter. The weight of the adapter plus the average PL mount prime is probably too much for a C lens mount. A zoom certainly would be too much.
