Nikon Z-mount


Nikon Z-mount is an interchangeable lens mount developed by Nikon for its full-frame mirrorless digital cameras. In late 2018, Nikon released two cameras that use this mount, the Nikon Z 7 and the Nikon Z 6. In late 2019, Nikon announced their first APS-C sensor size Z-mount camera, the Nikon Z 50.
Nikon SLR cameras have used the Nikon F-mount, with its 44 mm diameter, since 1959. The FTZ lens adapter allows many F-mount lenses to be used on Z-mount cameras.
The 55 mm diameter of the Nikon Z-mount is the largest in current use. It is much larger than the F-mount, the 46.1 mm Sony E that is used by all Sony mirrorless cameras, including those with a full-frame sensor but only slightly larger than the 54 mm of both the Canon EF and Canon RF mounts. It is also slightly larger than the new 51.6 mm diameter full-frame mirrorless L-mount from Leica, Panasonic and Sigma.
The introduction of the Z-mount also saw the re-introduction of the Noct brand, used to describe a forthcoming 58 mm S Noct lens with an ultra wide maximum aperture. This is one of the new lenses that Nikon will be developing, up to 2021, according to its "roadmap" published in late 2018.
