|SONNAR||Optical design invented by Ludwig Bertele in 1929. Lenses that use this optical design are lightweight and of high speed. The Sonnar designation comes from German word Sonne which means "sun" and emphasized the lens speed of 2.0 (that was extraordinary rare in those days). In comparison with Planar the Sonnar design has more optical aberrations but the contrast and flare control is much better. In comparison with older Tessar design it has less chromatic aberrations and the lens speed is higher. Due to short working distance the Sonnar design could not be used in wide angle lenses for SLR cameras. That's why Sonnar lenses for SLR cameras are generally available with focal lengths of 135mm or more.|

Design and Features
Extreme wide-angle, fast f/2.8 zoom lenses are among the preferred optics of today’s photojournalists and travel photographers.
For the Contax N SLR system, Carl Zeiss has designed an all new Vario-Sonnar T* 2,8/17-35 lens. With this zoom lens Carl Zeiss has incorporated 3 aspheric surfaces along with lens elements from special types of optical glass to achieve an image quality comparable to very good fixed focal length lenses, especially at the super wide end. This is particularly beneficial since extreme wide-angle photos should be blown up large, like a double spread, to really deliver that special impression of super wide vistas. For this purpose of high enlargements convincing sharpness is mandatory. The Vario-Sonnar T* 2,8/17-35 lens utilizes the full potential of modern color films and delivers images of impressive brilliance and sharpness.
To enable the use of special effect filters without any vignetting, the Vario-Sonnar T* 2,8/17-35 lens is equipped with a very wide filter mount. This lens with its large amount of optical glass, and attendant mass provides high stabilization during the exposure. Thus, significantly longer exposure times can be obtained handheld with good results, a special benefit for photojournalism. Equally beneficial is the fast speed of f/2.8, ensuring a bright viewfinder image thus easing the image composition.
Preferred use: spectacular super-wide vistas, advertising, images that depict sheer expanse, dynamic landscapes, travel and tourism, photojournalism, photos to be taken in crammed spaces.
The type of autofocus motor is indicated according to Conurus. The lens can be converted to Canon EF mount with AF support by Conurus service.
