Nikon Z-mount

Nikon Z-mount (stylised as ${\displaystyle \mathbb {Z} }$) is an interchangeable lens mount developed by Nikon for its mirrorless digital cameras. It was first used in 2018.

The 55 mm throat diameter of the Nikon Z-mount makes it the largest full-frame lens mount. It is much larger than the older Nikon F-mount (44 mm) and than the E-mount (46.1 mm) used by Sony mirrorless cameras but only slightly larger than the 54 mm of both the Canon EF and RF mounts. It is also slightly larger than the 51.6 mm diameter full-frame mirrorless Leica L-Mount. The Z-mount has also a very short flange distance of 16 mm, which is shorter than all mentioned lens mounts. This flange distance, along with the large throat diameter, allows for numerous lenses of nearly all other current and previous mounts to be used with an appropriate lens mount adapter on a Z-mount camera (see Autofocus/electronic adapters for a list of mounts and adapters).
