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 to 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
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.
