The Leica 35mm f/2 Summicron-MAspherical Lens is an aspheric lens surface technology for this long popular Leica 35mm M lens. Excellent sharpness and contrast rendition and high resolving power are the benefits of this new computation. This lens has outstanding imaging performance across the entire focusing range. Its versatility and all-around performance makes this a world class lens in the high-speed wide-angle category. Equipped with the 35mm f/2 Summicron-M Aspherical lens, the Leica M becomes an elegant compact camera. This lens is also available in a silver chrome plated version.
This lens has been updated with the "6-bit" coding, which allows the digital M camera to read this information optically and to identify which lens is being used. The camera can then (optionally) apply a "final stage" software based vignetting correction (for RAW images the lens used is simply recorded, no change is made).
The individual pieces of glass that form the overall optical construction. Most lenses have between four and eleven elements to bend the light rays to ensure a perfectly formed image appears on the light sensitive surface, such as a film or CCD. The elements are arranged in groups and may be seen in specification sheets as, for example, 6 elements in 4 groups. That configuration may have two single elements and the other four grouped in pairs.
