Bringing impeccable image quality to a wider perspective, Leica introduces the Super-APO-Summicron-SL 21mm f/2 ASPH Lens. A worlds first APO lens at this focal length, the 21mm f/2 is another addition to an already impressive array of APO-Summicron-SL lenses and features Leicas fast Dual Synchro Drive autofocus system. The combination of a bright f/2 maximum aperture and wide-angle view allows this lens to excel in several shooting scenarios including landscape, interior, street, and architectural photography. Being an APO lens, the 21mm f/2 dramatically reduces chromatic aberration and produces sharp, color-accurate images with ample contrast between your focal point and background. Leicas use of three aspherical lens elements and low-dispersion glass reduces color fringing and allows all colors to converge on the same focal plane. The autofocus system featured in Leica Summicron-SL lenses provides fast and silent focusing performance from 0.21m to infinity. With the combination of a constant aperture of f/2 and Leicas Dual Synchro Drive AF, this lens creates visually stunning video and panoramas.
