Nikon Z-mount
Nikon Z-mount (stylised as ) is an interchangeable lens mount developed by Nikon for its mirrorless digital cameras. In late 2018, Nikon released two cameras that use this mount, the full-frame Nikon Z 7 and Nikon Z 6. In late 2019 Nikon announced their first Z-mount camera with an APS-C sensor, the Nikon Z 50. In July 2020 the entry level full-frame Z 5 was introduced. In October 2020, Nikon announced the Nikon Z 6II and Nikon Z 7II, which succeed the Z 6 and Z 7, respectively. The APS-C lineup was expanded in July 2021, with the introduction of the retro styled Nikon Z fc, and in October 2021, Nikon unveiled the Nikon Z 9, which effectively succeeds the brand's flagship D6 DSLR. The APS-C lineup was further expanded with the Nikon Z 30, announced at the end of June 2022.

Nikon SLR cameras, both film and digital, have used the Nikon F-mount with its 44 mm diameter since 1959. The Z-mount has a 55 mm diameter. The FTZ lens adapter allows many F-mount lenses to be used on Z-mount cameras. The FTZ allows AF-S, AF-P and AF-I lenses to autofocus on Z-mount cameras. The older screw-drive AF and AF-D lenses will not autofocus with the FTZ adapter, but they do retain metering and Exif data. Z-mount cameras support metering as well as in-body image stabilization (IBIS) with manual focus lenses.
The 55 mm throat diameter of the Nikon Z-mount makes it the largest full-frame lens mount. It is much larger than the F-mount and the E-mount 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.
The Z-mount 58 mm f/0.95 S Noct lens reintroduced the Noct brand historically used by Nikon for lenses with ultra-fast maximum apertures.
Nikon published a roadmap outlining which lenses are forthcoming when the Z-mount system was initially announced. The roadmap has been updated multiple times. As of November 2023 the current version of the roadmap indicates a 35 mm lens left to be released within 2023.
