Contax 645 AF Vario-Sonnar T* 45-90mm f/4.5

Manufacturer's Description:

"The Vario-Sonnar T* 90mm f/4.5 lens is an all-around auto-focus lens for the Contax 645. It is particularly well suited for demanding photojournalistic work, where prints may be enlarged to poster size with fine details that cannot be reliably captured with 35mm cameras. Weddings, travel, and industrial photos for annual reports and business presentations are typical tasks of this kind, where medium format has proven to be indispensable. Imaging performance of the Vario-Sonnar T* 90mm f/4.5 lens is on the level of fixed focal length lenses. Both sharpness and brilliance satisfy even high demands, while distortion is very well corrected.
Preferred use: Demanding photojournalistic work, Weddings, Travel, Street photography, People, Industrial and forensic documentation"
