The Samsung NX-mount serves as the lens attachment system for Samsung's NX series mirrorless interchangeable lens cameras. This mount debuted with the Samsung NX10 model, with Samsung initially branding the NX lineup as 'hybrid digital cameras' due to their blend of features typically found in both DSLR and compact cameras.
Engineered to accommodate APS-C image sensors, the mount supports a 1.54x crop factor. Certain lenses within this system incorporate optical image stabilization, denoted by the "OIS" label. Autofocus functionality in NX lenses is driven by an integrated electric motor housed within each lens.
Most Samsung NX lenses, aside from a few early models, are equipped with i-Function (iFn) technology. This feature enables users to adjust various camera parameters through a control ring and button located on the lens itself. Firmware updates 1.10 and 1.20 introduced iFn compatibility to the NX5 and NX10 cameras respectively, while all later models offer native support for iFn.

Lenses roadmap
In December 2011, Samsung revealed intentions to release a 16-80mm Template:F/3.5-4.5 lens featuring OIS and a VCM mechanism (Movie Home).
Back in June 2010, Samyang Optics introduced three manual focus lenses: an 8mm Template:F/3.5 Fisheye, a 14mm Template:F/2.8, and an 85mm Template:F/1.4. Later that year at the photokina 2010 exhibition held in September, Samyang Optics announced the launch of a new 35mm Template:F/1.4 lens designed for the NX mount.
Additionally, Lensbaby made its Composer Pro model compatible with the NX mount by offering it with various optical configurations.
Adaptation to non-NX lenses
Samsung announced the ED-MA9NXK adapter to enable the use of K-mount lenses on NX cameras. Moreover, Novoflex manufactures a range of adapters that allow lenses from mounts such as Nikon F-mount, Canon FD lens mount, Minolta SR mount, Minolta AF, Sony A-mount, Leica R bayonet, Pentax K-mount, Olympus OM system, M42 lens mount, and T2 to be fitted onto NX bodies. Kiwifotos also supplies various adapters supporting these conversions.
Because the NX system has a relatively long flange focal distance compared to other mirrorless designs, creating telecompressor adapters posed challenges. However, in 2017, a community-funded NX-L telecompressor adapter was introduced.
