|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 Sonnar® T* 2.8/85 lens is the most compact telephoto lens in the Contax SLR system. It is as small and lightweight as a 50 mm f/1.4 standard lens. Thus it is a great lens for travelling with the Contax and it was widely used in applications like photojournalism. 85 mm is a very popular and flexible focal length for portrait photography, too, especially on location.
The Carl Zeiss Sonnar® T* 2.8/85 lens delivers stunning sharpness and contrast - even at full aperture of f/2.8. In combination with modern color films or professional digital receivers this lens can produce photos with details delivered so clear that the images can be easily printed in full page size - even two-page spreads are possible - within high quality brochures and on covers of glossy magazines. The results are convincing.
The Carl Zeiss Sonnar® T* 2.8/85 lens comes with a precision barrel made of metal. This ensures smooth and precise focusing and long lasting performance, even if the lens is used extensively and is subjected to considerable fluctuations of temperature and humidity which tends to happen quite often in travel and photojournalistic photography. The Carl Zeiss Sonnar® T* 2.8/85 lens is a must-have item for photographers seeking high performance in a small and lightweight package.
