Mounting and Removing Lenses The camera accepts a wide variety of M-type bayonet mount (M-mount) lenses. You can also use L-type screw mount (L-mount) lenses by attaching a third-party adapter ring. Incompatible Lenses Certain lenses are not compatible with the camera due to physical constraints: ❏ Lenses that project more than 20.5 mm into the camera body. These lenses cannot be used because they may touch the inner parts of the camera. Some models known to be incompatible include: ❏ Hologon 15 mm F8 ❏ Super Angulon 21 mm F3.4 ❏ Super Angulon 21 mm F4 ❏ Elmarit 28 mm F2.8 (earliest model) ❏ Summicron 50 mm (Dual Range Summicron) ❏ Collapsible lenses. However collapsible lenses such as the Hektor 50 mm F2.5 or the Elmar 50 mm F3.5 can be used with the camera as long as the lens barrel is not pushed into the camera body. Be very careful if using these types of lenses. ❏ Lenses that have an auxiliary viewfinder lens. These lenses cannot be used effectively because the baseline length is different from the one used for this camera. Mounting an M-mount Lens 1 1.
