Leica APO-Summicron-M 50mm f/2.0 ASPH, silver anodized finish
SKU: 799429111427 Mfg Code: 11142
The Leica APO-Summicron-M 50mm f/2 ASPH is now also available in a silver anodized version. Thanks to the perfect interaction of all parameters, from optical design and choice of materials to sophisticated and elaborate manufacturing and finishing, this high-performance lens is considered to be the reference lens amongst standard focal lengths. It impresses with exceptional imaging performance and sharpness that captures and resolves even the finest details.
The APO-Summicron-M 50mm f/2 ASPH standard lens is characterized in particular by extremely high contrast rendition from corner to corner of the image at maximum aperture and throughout the aperture range. The utilization of a floating element in its design ensures that this is also maintained to a great extent at close shooting distances. A total of eight lens elements are employed to achieve its exceptional optical performance. Three of these are made from glass types with anomalous partial dispersion to apochromatic correction and two of the others have a high refractive index. The specially formulated glass types employed are based on original developments from the former Leitz glass laboratory. The use of such glasses requires great effort and many years of experience. Thanks to the consistent advancement of optical technologies, processes have since been refined and perfected to achieve the best possible imaging qualities.
As is the case for all other Leica lenses, the Leica APO-Summicron-M 50mm f/2 ASPH was designed and developed by Leica optical specialists in Wetzlar and represents the perfect combination of optical and technical expertise. As a particularly reliable product with enduring value with the quality guarantee “Made in Germany”, this lens is manufactured from the finest materials and is assembled completely by hand in an elaborate process. The combination of cutting-edge technologies and painstaking manufacturing procedures guarantees consistently excellent quality.
