The Leica-Elmarit-S 45 mm f/2.8 ASPH. is a new wide-angle lens for the Leica S-System. Available with or without a central (leaf) shutter, the Leica-Elmarit-S 45 mm f/2.8 ASPH. has an optical formula comprising 12 elements in 9 groups, a focusing range of 60cm to infinity, and a diagonal angle of view of 62 degrees. Three lens elements made from glass with anomalous partial dispersion minimise chromatic aberrations, and two further elements are manufactured from glass with particularly low dispersion. An additional lens element with an aspherical surface minimises monochromatic aberrations. Thanks to its extremely elaborate optical design and construction, the lens also offers excellent control of flare to ensure high-contrast images, even when shooting a backlit subject. The suggested retail price for the Leica Elmarit-S 45 mm f/2.8 ASPH. without an integrated leaf shutter is £4,650; the SRP for the central shutter (CS) versionof the lens is £5,500.
