What is the difference between C and CS lens?

C-Mount vs. CS-Mount vs. S Mount

One of the first questions inevitably asked when people begin purchasing camera hardware is a variant of the following:
- Will my CS Mount Lens work with my C Camera Mount?
- Will my C Mount Lens work with my CS Camera Mount?
- What is the difference between a S Mount lens and a M12 lens?

If you've asked one of these questions, have run into an incompatibility, or just want to learn, you've found the right page! We've found that there are few easy-to-find simple answers to this frequently asked question and have put a brief introduction together just for you.

Matching a lens type with mount type can be frustrating if you've purchased a lens and discovered that it cannot focus on your camera. If you are running into this problem, you're not alone! We've put together the compatibility matrix below to help you determine if you accidentally chose an incompatible lens for your camera.

For M12 "S-Mount" Lenses, a mechanical comparison is needed between the lens, the lens mount, and the camera housing. Each M12 (S Mount) lens mechanical design has different constraints as this mount type is not standardized. The back focal length and diameters of S Mount lenses are frequently incompatible with CS and C Mount cameras, resulting in a lens-to-mount combination which cannot be focused.
