Lens mounts at a glance

Numerous different lens mounts for interchangeable lenses have been introduced in the recent years.

The lens bayonet is not only used to attach interchangeable lenses to the camera, it is also used to transfer various controls and information between camera and lens. These include aperture and focus control as well as the lens image stabilization function.

The lens transmits information to the camera about the lens type, focal length or range of focal lengths of the product, speed, current aperture and focal length, and various other things. This communication takes place largely electrically/electronically with newer lens mounts; older lens mounts such as the Leica-M bayonet, the Nikon-F bayonet or the Pentax-K bayonet also use mechanical transmission methods.

There are numerous different lens mounts for interchangeable lenses. Almost every camera manufacturer has his own lens mount, some manufacturers even have several mounts in use for different camera systems.

For the increasingly popular full-frame DSLM cameras, new lens mounts have been introduced in the last two years. Canon introduced the new R bayonet for its full-frame camera Canon EOS R. With the Z bayonet, Nikon launched a new lens mount for the Nikon Z6 and Nikon Z7 full-frame system cameras. The range was complemented by the alliance of Leica, Panasonic and Sigma, who jointly introduced the L bayonet for digital full-frame and APS-C system cameras, accompanied by Panasonic's full-frame cameras S1R and S1 and camera announcements from Leica and Sigma.

The Nikon F bayonet has been around since 1959 and can also be found on the current Nikon D750. With it more than 400 different Nikon lenses can be used.
