The Contax 645 AF is a 6×4.5cm medium format, autofocus film camera, introduced by Kyocera under the Contax brand in 1999. Competing cameras include Pentax 645N and Mamiya 645 AF. The camera system was discontinued in 2005.

The camera system has a range of interchangeable lenses and finders. The body materials are similar to their Contax RTS 35mm SLR cameras.

The metering TTL system is can be used in either spot or center-weighted modes. Exposure modes include AV (aperture priority), TV (shutter priority) and manual exposure mode. Exposure compensation can be in -3 to 3 EV in 1/3 steps. Flash exposure modes include TTL auto flash, TTL auto pre-flash and manual pre-flash modes.

The vertical travelling electronic focal plane shutter design has a maximum speed of 1/4000 of a second. In AV mode: 30 sec to 1/4000, in TV mode, 8 sec to 1/4000. There is a bulb mode and flash sync is also available at 1/125 of a second. Electronic self timer can be delay with either 2 or 10 seconds.

The Carl Zeiss lenses are developed with a built-in motor which allows auto and manual focus override without having to change lens modes.

It uses interchangeable, removable film backs with an insert available for both 120 and 220 film. The back has a memo holder used for a emulsion reminder. The back uses a dark slide system, to change film backs without loosing exposures. The film loading is automatic with bar coded film and will automatically advance to the first frame. Non coded film requires aligning the backing paper start indicator. Bar code film ISO can be read automatically with a range of 25 to 5000 ISO. It can also be manually set from 6 to 6400 ISO. The film transport system is motorized, with automatic advance of up to 1.6 fps. It is powered by a 2CR5 battery.
