Contax 645 Planar T* 80mm f/2

Manufacturer's Description:

"The Carl Zeiss Planar lens is the most successful camera lens design ever created. This nearly symmetrical layout provides the lens designer with numerous means to correct aberrations extraordinarily well, even at open apertures. This design is the ideal basis for high-performance lenses with great color correction, high speed, flat image plane (where the name Planar originates) and low distortion. The Planar design is the basis for nearly all professional "workhorse" lenses, used on earth and in space today.

At f/2, the Planar T* 80mm lens is the fastest lens in the Contax 645 system. There is no faster Planar lens in medium-format photography available anywhere! Even at full aperture, the performance of the Planar T* 80mm lens is so high that professional quality images are reached. This lens design is especially beneficial in the Contax 645, which provides for quick and accurate focusing, where manual focusing is too slow or not accurate enough for f/2.
