The Zeiss 120mm f4 Makro Planar is the only manual focus lens made by Kyocera for the Contax 645 system. As the "Makro" in its name suggests, this lens has a very long focus travel that focuses all the way down to a 1:1 reproduction ratio, meaning that the size of an object recorded on film is the same as the true size of the object. This close-up capability allows the Zeiss 120mm f4 to capture details that most medium format setups can only dream of. The Contax 645's fast and accurate light meter makes automatic exposure compensation for barrel extension at macro distances, allowing the photographer to focus solely on the subject.
