Leica 50mm f/2 APO-Summicron-M Aspherical Lens for M System, Silver

The Leica APO-Summicron-M 50mm f/2.0 ASPH is a premium, hand-made, compact normal prime lens for the Leica M rangefinder camera that delivers superior image quality for the most discerning photographer. MTF chart test results show this to be one of the highest-rated lenses ever made, with corner-to-corner sharpness at all apertures, and over 50% contrast. A manual focus lens with clear foot/meter and depth-of-field indicators on the lens barrel, this lens virtually eliminates vignetting, imperceptible linear distortion, and extremely high sharpness and resolution. This lens is especially designed for photojournalists, street photographers, portrait photography and travel photography. What you should know about this lens: • Best image quality: Hand-built to precise specifications, the lens is made with superior glass that produces absolutely no image degradation at f/5.6, vignetting restricted to 2 stops at full aperture, and 0.4% pincussion distortion, which is practically imperceptible. • Best in class glass: The lens has 8 lens elements with apochromatic correction, reducing in sharp edges throughout the frame, plus high anomalous partial color dispersion in three lens elements, while the other five elements have a high refractive index. • Fantastic focus: Image quality is consistently outstanding throughout both the entire focus range and at all apertures.
