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. The optical performance and specs of each focal length do vary. The 16mm is constructed from 16 elements in 13 groups including three FLD glass elements, two SLD glass elements, and two molded glass aspherical elements. It rivals the popular Art series in terms of performance. The 30mm has 9 elements in 7 groups with two aspherical elements, and the 56mm has 10 elements in 6 groups with two SLD glass elements.
The filter size of the focal lengths varies as well from 67mm on the 16mm, 52mm on the 30mm, and 55mm on the 56mm. This makes it difficult to use a single set of ND filters across the focal range. However, all three lenses do tout a stepping motor for for quick and quiet autofocus performance. The lenses are also compatible with Sony E-mount Fast Hybrid AF if are a Sony user. In addition to L-mount and Sony E-mount, the lenses are available for Canon EF-M and Micro Four Thirds camera systems.
