Sigma adapts its Contemporary prime lenses for L-mount. Three Sigma lenses now include an L-mount option, the alliance between Leica, Panasonic, and Sigma. The trio includes the 16mm, 30mm, and 56mm F1.4 DC DN Contemporary lenses designed for APS-C size cameras. Sigma also announced two telelconverters and a full-frame 100-400mm telephoto lens. Besides the change in bayonet, the optics remain the same. Each focal length shares the same 9 blade aperture design, fast aperture range of F1.4 to F16, and a mount with dust- and splash- proof construction.
