for interchangeable-lens autofocus digital cameras. The L-Mount has an inner diameter of 51.6 mm and a flange depth of 20.0 mm. 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

On 25 September 2018, the L-Mount Alliance between Leica,

and

was announced, enabling the partners "to make use of the L-Mount standard developed by Leica for their own developments and to offer both cameras and lenses utilising this lens mount" with full compatibility between the three companies' products. According to Sigma CEO, Kazuto Yamaki, the "L-mount system is not exactly the same as the existing one. We updated it a little bit to work better with such lenses through lens adapters." On the same day, Panasonic announced its S1R and S1 full-frame L-Mount cameras and three L-Mount lenses, with seven more lenses to be launched by 2020. Sigma announced that it will launch a full-frame camera in 2019, using the L-Mount and the company's
