One of the most versatile lenses available for Leica M-mount rangefinders, the black Summilux-M 35mm f/1.4 ASPH. is a general wide-angle lens characterized by its sophisticated optics and bright f/1.4 maximum aperture. The fast lens is well-suited for available light photography and also affords greater control over depth of field for selective focus shooting. The optical design incorporates one aspherical element to control spherical aberrations and distortion for improved sharpness and clarity, and a floating elements system is used to maintain performance throughout the focusing range.
