Leica 90mm f/2.0 APO-Summicron-M Aspherical Lens for M System, Black

With the Leica Apo-Summicron-M 90mm f/2 ASPH. light fall-off is very low. Its fast aperture lets you shoot at a relatively short exposure time - even in dim light. The result is a minimized camera shake, even when shooting street scenes from a distance. Thus the APO-Summicron-M 90mm f/2 ASPH. is ideal for photojournalism, theatre and even portrait photography. This lens is unique because apochromatic correction and an aspherical surface are combined for the first time. Two of the five lens elements are made of high-refraction optical glass, and two others make judicious use of anomalous partial dispersion. Brilliance and resolving power are already outstanding at full aperture. Artificial vignetting is extremely low. These features lead to superlative results in every application: such as portraiture, reportage or studio photography. In addition, its compact design and high speed make it ideal for hand-held photography.
