Also known as the 'RB67 Roll Film Holder', this Mamiya 120 Film Back for RB67 System is the original 6X7 format back/magazine for the Mamiya RB67 Professional camera system. The back uses 120 roll film, fitting 10 frames on a roll. The back doesn't technically attach directly to a RB67 body, instead it attaches (via 2x3 Graflok style 'G-lock' connection) to another modular component: the RB67 Revolving Back Adapter (which normally stays attached to the camera body). The Revolving Back Adapter notably allows the Film Back to rotate 90° for quick and easy switching between vertical and horizontal compositions without needing to reposition the camera. The back features a double exposure 'Warning signal window' that changes red after a shot. While it does not feature a locking darkslide or ADEP (Automatic Double Exposure Prevention),the back is compatible with all three Mamiya RB67 Professional system models: the original RB67 Pro, RB67 Pro S, and RB67 Pro SD bodies. Mamiya introduced this model in 1970. An updated version was released in 1974, the Pro S 120 Roll Film Holder.
This is a complete back consisting of three parts: the Outer Shell (sometimes called the Outer Cassette), the 120 Insert (which holds the film), and a Darkslide. The Darkslide can be stowed vertically flat against the left side of the camera body while shooting. Also available with a 220 insert. 120 and 220 Inserts are interchangeable but only among the same generation of Shell/Cassette: non-Pro with non-Pro, Pro-S with Pro-S, Pro-SD with Pro-SD. RB backs are not interchangeable with RZ backs.
