Samsung NX lens
The Samsung NX-mount lens is the mount used on NX series mirrorless interchangeable lens cameras by Samsung. The mount was first implemented in the Samsung NX10, and Samsung initially referred to the NX line as 'hybrid digital cameras', citing their combination of attributes of both DSLR and compact cameras.
The mount is designed for APS-C image sensors, and therefore has a 1.5x crop factor. Optical image stabilization is featured on some of the lenses, indicated by an "OIS" marking. Automatic focusing on Samsung NX lens is handled by a dedicated electric motor built into the lens.
Samsung NX lens (with some early exceptions) include i-Function (iFn), which allows control of various camera settings via a ring and button on the lens. NX5 and NX10 cameras support iFn since firmware 1.10 and 1.20 respectively, while all subsequent models support iFn natively.
