The Leica L-Mount is a bayonet mount developed by Leica Camera AG for interchangeable-lens autofocus digital cameras.
The L-Mount has an inner diameter of 51.6 mm[1] and a flange depth of 20.0 mm.[2] The L-mount exists in two versions, an APS-C version (TL) and a full-frame version (SL). The two versions are mechanically and electronically compatible. TL lenses mounted on full-frame cameras will cause the camera to use a crop mode from the center of the sensor, corresponding to the APS-C coverage of the lens. SL lenses mounted on TL cameras function normally, providing a 1.5x crop field of view, as is typical with APS-C cameras.
In 2018 Leica formed the L-Mount Alliance, licensing Sigma, Panasonic in the same year, to use an upgraded version of the mount for their own products, opening the way for a more extensive system of fully compatible cameras and lenses.[3]
Ernst Leitz Wetzlar GmbH, the cine lens business of Leica, joined the L-Mount Alliance in 2021,[4] DJI followed in 2022,[5] Samyang, Astrodesign[6] and Blackmagic Design in 2023.[7]
