Which mount type has an outer thread diameter of 1 inch?

M-12 mount

CS-mount

C-mount

The C-mount is recognized for its outer thread diameter of 1 inch, which is essential when considering camera lens compatibility and attachment mechanisms. This standardized mounting type was developed for 16 mm film cameras but has been widely adopted in various applications, including industrial and video cameras.

Using a C-mount allows for the secure attachment of lenses, ensuring that they fit reliably and align correctly with the image sensor. The size and diameter facilitate a greater choice of lens options, including wide-angle and telephoto varieties, which can be essential depending on the specific imaging requirements of a project.

While other mount types exist, such as the M-12 mount with a significantly smaller diameter, the CS-mount, which has a slightly different design intended for certain compact cameras, and fixed mounts that serve specific application needs, none of them match the 1-inch diameter characteristic of the C-mount. Understanding these specifics ensures that a user can select the appropriate mount for their camera system, optimizing for both performance and versatility.
