Contax Telephoto 400mm f/4 N-AF Tele-APO Tessar T* Autofocus Lens

As the longest lens in the Contax N AF system, this is the perfect high-quality solution for those otherwise inaccessible objects and acctions. For the Contax N SLR system, Carl Zeiss has designed an all new autofocus Tele-Apotessar® T* 400 f/4 lens. It is relatively fast, yet handy enough to be used without a tripod. This lens produces images of stunning sharpness and brilliance - delivering high image quality even fully open, and over the entire frame. Field flatness is immaculate. And so is field illumination.
