The L-Mount Alliance is an alliance between Leica Camera AG, Panasonic and Sigma, launched on 25 September 2018, whereby Panasonic and Sigma will make use of the L-Mount standard initially developed by Leica and will offer cameras and lenses utilising this lens mount with improved firmware and full compatibility among these Alliance products.[1][2]

On the same day, Panasonic announced its S1R and S1 full-frame L-mount cameras[3], and Sigma announced a full-frame L-mount camera using the company's unique Foveon sensor technology.[4][5] Panasonic's cameras will launch with three new lenses, and Sigma will initially release the same L-mount variants of existing lenses as they are producing for the Sony E-mount.[2][6]

Six cameras and 39 native lenses have been announced for the L-Mount by 2020.
