Leica is partnering with Panasonic and Sigma to collaborate on the L Mount Full Frame Alliance. There will be Cameras that use the L Mount system and compatible with Leica, Sigma and Panasonic lenses for it. Sigma will also make compatible cameras and lenses. APSC and full frame lenses will be compatible with L Mount systems. The new alliance provides greater cooperation, greater company specialization, and more choices for consumers to bring new choices for the full frame camera market.
