Frequently asked questions

Which brands use the L-Mount?

Leica introduced the L-Mount in 2014 with the Leica T and founded the L-Mount Alliance with Panasonic and Sigma in 2018. Members now also include Samyang, Blackmagic Design, DJI, Viltrox, Sirui, Astrodesign and Ernst Leitz Wetzlar. That is why L-Mount cameras and lenses come from several manufacturers.

Can you use L-Mount lenses from different brands on any L-Mount camera?

Yes. Cameras and lenses from the L-Mount Alliance share one mount specification, so lenses from Leica, Panasonic and Sigma fit each other's cameras. The alliance was formed in 2018 to create a system of fully compatible cameras and lenses.

Can you use APS-C L-Mount lenses on full-frame cameras?

Yes, the APS-C version (TL) and the full-frame version (SL) are mechanically and electronically compatible. With a TL lens, a full-frame camera uses a crop mode from the center of the sensor. An SL lens on an APS-C camera works normally and gives a 1.5x crop factor.

Can you use other lenses on L-Mount cameras with adapters?

Yes. Leica offers adapters for its M, R and S lenses (M-Adapter L, R-Adapter L, S-Adapter L), and Sigma's MC-21 adapts lenses with a Canon EF or Sigma SA mount. Sigma's own Global Vision EF lenses are fully supported, while other EF lenses are not guaranteed. Third-party adapters exist as well, for example the Viltrox EF-L.

What is the difference between L-Mount and Sony E-mount?

They are two different, incompatible mounts. The L-Mount has a 20 mm flange distance and a 51.6 mm inner diameter and is used by Leica, Panasonic, Sigma and other alliance members. Sony's E-mount has an 18 mm flange distance and is open to many lens makers under license. Lenses cannot be swapped directly from one mount to the other.
