This Carl Zeiss Tele-Apotessar T* 350mm f/4.0 lens is an autofocus telephoto lens with a focal length comparable to a 210mm lens on a 35mm camera. This optical system was designed using state-of-the-art technology, incorporating internal focusing and two ultra-low dispersion lens elements. It was designed with a minimum focus distance of 5.8 feet, virtually placing it into the macro range. This lens also comes with a detachable tripod collar. When used with the optional Mutar 1.4x teleconverter, the resulting lens is a 490mm f/5.6. Such a combination is eminently useful for many applications including wildlife and sports photography.
