Leica Summicron-M 28mm f/2.0 ASPH

This super fast wide-angle lens has been a benchmark product since its launch. It is highly compact, and from maximum aperture on down it delivers outstanding picture quality. Its ultra-fine detail rendition yields pictures of extraordinary plasticity. Even under critical lighting situations, such as when shooting into the light, disturbing reflections and diffusion are largely eliminated. With its 75° wide angle, it captures a wide enough frame for lively reportage situations. The high aperture of f/2.0 enables creative selective focus to be employed even for wide-angle shots. And this lens is particularly recommended when shooting in difficult lighting conditions, such as at dusk or in dimly lit rooms with no flash.
