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 and Panasonic 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]

T-Mount to L-Mount[]

It was introduced in April 2014 with the Leica T (Typ 701) camera. At the time of introduction, it was called the "T-mount", but this was changed to "L-mount" with the release of the Leica SL, a full-frame sensor camera using the same mount. The Leica T was renamed to the Leica TL at this time,[4] to permit marketing clarity for the L-mount lens line: TL lenses would cover APS-C sensors, while SL lenses would cover full-frame sensors.

The mount is used by the Leica TL (discontinued), TL2, Leica CL (2017) and Leica SL systems. The L-Mount is a registered trademark of Leica Camera AG.

L-Mount Alliance[]

Main article: L-Mount Alliance

On 25 September 2018, the L-Mount Alliance between Leica, Panasonic and Sigma 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.[5]

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."[3]

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.[6][3]

Sigma announced that it will launch a full-frame camera in 2019, using the L-Mount and the company's Foveon sensor, as well as a range of L-mount lenses and adapters for Sigma SA and Canon EF lenses.[7]

Six cameras and 39 native lenses are confirmed for the L-Mount by 2020.

Cameras[]

APS-C[]

Leica T/TL cameras use APS-C sensors. The TL mount version is not dust- or splashproof.

Superseded[]

Current[]

Full-frame[]

Leica SL cameras use full-frame sensors. The SL version is dust- and splashproof.

Current[]

Withdrawn[]

  • Unspecified Foveon-based full-frame Sigma[11]

Lenses[]

Leica has an existing range of fifteen L-Mount lenses.[12]

Panasonic committed to releasing a total of ten lenses for the L-mount by the end of 2020, beginning with the 50mm F/1.4 prime and the two zooms listed below; stating that they would provide details at Photokina 2019. [13]

Sigma plans to release a wide range of lenses. 14 primes from Sigma's 'Global Vision' range, primarily designed for reflex cameras with short flange depths and currently available for the mirrorless Sony E-mount, will also be released in L-Mount from 2019.[3][14] These will be followed by a range designed specifically for mirrorless parameters.
