ZEISS lenses are suitable for digital Sony Alpha cameras and have been optimized for film and sensors up to full 35 mm format (24 x 36 mm).
Impressive photographs captured in low light always begin with a fast lens for a system or SLR camera. Because, a fast, high-performance lens captures as much light as possible. And a lens with a large maximum aperture leads to the best results when shooting in unfavourable light.
Design of the autofocus system requires extremely accurate shifting of particular lens groups. While this is normally achieved via mechanical coupling from the camera body, ZA lenses feature a built-in SSM (Super Sonic wave Motor) focusing system for even more refined AF performance.
The optical elements of ZEISS lenses feature T*® anti-reflective coating on all surfaces and an optical design that guarantees images of superior brilliance at all times, even in unfavourable lighting conditions. We apply the anti-reflective coating to the lens surfaces by the vapour deposition of extremely thin, transparent layers on the glass. In this process, special substances are vaporized with extremely high energy in a high-vacuum environment and are subsequently deposited on the glass surfaces, one after another, as layers with precisely controlled thicknesses to achieve the desired reduction of reflective properties. The first coating techniques were employed by ZEISS as long ago as in the 1930s.
