|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.|
|T*||The multi-layer coating is applied to the surface of lens elements. It boosts light transmission, ensures sharp and high contrast images, minimizes ghosting and flares.|

Design and Features
The Carl Zeiss Vario-Sonnar T* 3.5-5.6/35-70 lens is an easy-to-carry zoom lens for the Contax G 2 rangefinder system camera.
It is the first “real”zoom lens in the world with continuous focal length setting for a rangefinder system camera with interchangeable lenses. The built-in zoom viewfinder of the Contax G 2 camera automatically adjusts to the Vario-Sonnar T* 3.5-5.6/35-70 lens zoom setting.
With the range of focal length from 35 mm to 70 mm broad range of uses from wide angle 35 mm and standard 50 mm focal lengths for natural subject renditions to medium-telephoto 70 mm focal length allowing easy shooting with natural-looking perspective and relative distance between objects.
Thus the Vario-Sonnar T* 3.5-5.6/35-70 lens is the ”natural travelling companion” in the Contax G-system world.
Preferred use: action, travel, photojournalism
