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
preferred optics of today’s photojournalists and travel

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
