Since its launch, the Leica Apo-Summicron-M 75mm f/2 ASPH. has set new performance standards in the Leica rangefinder system. The speed of this powerful lens gives it a particularly wide range of uses from portrait to reportage photography and it counts as one of the best lenses in the M system. Used with the digital Leica M9, the application potential of this telephoto lens is enhanced even further. The focal length extension factor of the digital rangefinder camera turns the compact lens into a powerful telephoto lens with a focal length of 100 mm, making it an ideal partner of ambitious Leica M8 photographers.
The compact Leica Apo-Summicron-M 75mm f/2 ASPH. harnesses all the technical possibilities of today's high-performance optics to achieve a combination of high speed and remarkable imaging quality. It features aspherical surfaces, special glass types with partial anomalous dispersion and floating elements. It is the ideal lens on either an analog or digital Leica rangefinder camera delivering intimate views of scenes, nature, landscapes and people, irrespective of whether they are at infinity or at the close-focus range of the lens. With resolving power well above that of the best colour photo films, it is also a first-rate documentary tool.
