A popular wide-angle lens for the Leica M rangefinder system, the black Summilux-M 35mm f/1.4 ASPH Lens from Leica provides high quality optics for excellent performance in a variety of applications. The aperture range starts at a fast f/1.4 for available light and stops all the way down to f/16 for use in many scenarios, such as landscapes or images requiring great depth-of-field. The optical design also allows this lens to remain compact with 9 elements in 5 groups, of which one has an aspherical surface to assist in control of aberrations.
