- Technical Specs
With an angle of view corresponding to that of a 28 mm lens in 35 mm format, the Leica Summarit-S 35 mm f/2.5ASPH. can be used as a universal wide-angle lens with characteristically dramatic perspectives. At the same time, its unusually fast initial aperture offers fascinating creative potential for the use of selective focusing to isolate subjects from their surroundings. The alternative CS version with a central shutter and a close focusing limit of only 55 cm (~1.8 ft), offers extreme versatility for a wide range of photographic needs.
