What are the lens mounts in Canon EOS R System?

Lens mount is considered as a proprietary and standard interface for camera and the manufacturers at Canon make sure to design highly secure and reliable mount systems that can suit the body of the camera.

All the camera units these days make use of unique mounts, and they often limit compatibility with different types of lenses.

The lens mounts also provide a way to do electronic communication between camera and lens so that users can achieve higher exposure and better focus.

New RF Lens Mount for Canon EOS R System

Most of the lens mounts that are being used at the present time in the market are bayonet-type where the lens is directly attached to the body of the camera by registering it with accurate orientation and then it requires a small twist of angle 45-90 degrees to lock that lens at the right place.

Note that, before the invention of Bayonet mount, manufacturers were using few other styles for mounting; they were names as breech-lock mounts and thread mounts.

Here, the thread mounts or the screw mounts are considered as self-referential systems and they simply thread the lens into the body of camera same as the nut is threaded into the bolt.

On the other side, the breech lock mounts closely resemble the bayonet mounts; with additional self-contained type rotating ring that helps to tighten the lens to the body of the camera by friction.

Most experts prefer using bayonet mounts due to their faster installation, removal ability and ease of use.

Adapters are capable enough to bridge formats; they enable paths between Micro Four Thirds, APS-C, full-frame and medium format to coverage.
