The Nikon Z-mount is a lens mount system introduced by Nikon for its mirrorless cameras. Launched in 2018, it features a larger diameter and shorter flange distance compared to previous Nikon F-mount systems, allowing for improved optical performance and design flexibility. The Z-mount supports a range of Nikon Z-series lenses, which are designed to take advantage of the mount's capabilities. This system also allows for the use of F-mount lenses with an adapter, providing users with more options while transitioning to mirrorless technology.
