A bright wide-angle prime with consistent performance throughout the aperture range, the Leica Summicron-M 28mm f2 ASPH. Lens is well-suited To reportage and environmental photography in a variety of working conditions. Aside from the wide perspective, this 28mm f2 is also characterized by a sophisticated nine elements in six groups design, which incorporates a single aspherical element To control distortions and spherical aberrations throughout the focusing and aperture ranges. The optical design further contributes To refined handling of lens flare and ghosting, and maintains a high degree of sharpness even when working at f2. An indispensable prime for highlighting your environment, the compact stature, smooth manual focus control, and bright maximum aperture make this a truly versatile option for M shooters.
One aspherical element is featured in the optical design To reduce spherical aberrations and distortions for increased sharpness and clarity. This design also contributes To a marked reduction of astigmatism and promotes edge-to-edge sharpness throughout the aperture range.
Bright f2 maximum aperture benefits working in difficult lighting conditions.
Manual focus design provides a minimum focusing distance of 2.3' with a maximum magnification ratio of 1:21.9.
The front of the lens has 46mm-diameter threads To accept optional filters, and the lens is male threaded To accept the included lens hood.
