How to use C-mount as CS-mount

Screw diameter is exactly the same for C mount and CS mount.

It only differs from the back flange (the distance from the end of the lens to the image sensor).

CS mount is shorter by 5 mm.

Depending on the camera, 5 mm thick ring (C mount ring) may be attached to the tip to make C mount.

Therefore, if you remove C mount ring, it becomes CS mount.
