The 70mm film format is mainly used by the movie industry. Despite its name, the actual film loaded in the cameras is 65mm wide, perforations included. For the distribution of the movie the original film is transferred to 70mm wide film, where the additional 5mm used for the sound channels.

Some still cameras can use 70mm film, usually via a specially designed interchangeable back, for example Hasselblad. Very few models were designed for exclusive use of the 70mm film: the Combat Graphic was one of them.

Most of these cameras use preloaded cassettes containing 15 feet of film, and looking like overgrown 35mm film cassettes.
