Contax G mount was introduced in 1994. It is an electronic, autofocus mount made for 35mm-format rangefinder lenses. There is an electronic connection between the lens and camera to transmit data, but lenses have no AF motor and no means to adjust focus, focusing a lens is made by driving the focus motor in the camera, even in manual focus mode. Focusing is done by slotted “screwdriver” coupling, its autofocus system uses a twin-window rangefinder mechanism, just like a traditional, mechanical rangefinder.<\/p>\n\n\n\n
The mount has four tabs and uses a breech-lock mechanism. Its focal flange distance is 28.95mm and its throat diameter is 44mm. It is used on two cameras and seven Carl Zeiss-branded lenses. Vario-Sonnar lens was the first zoom lens for a rangefinder camera, at the time of introduction, in 2000. The only lens that does not feature autofocus is the Hologon 16mm lens; it has a fixed \u0192\/8 aperture.<\/p>\n\n\n\n
The Contax G lens system was officially discontinued by Kyocera in 2005.<\/p>\n\n\n\n
