The RZ67 is a modular camera system, meaning the lenses, viewfinders, ground glass, film winders and film backs designed for the system are all interchangeable. The RZ67's Sekor lenses have built-in electronic leaf shutters which are cocked and triggered from the body. Focusing is performed with a set of bellows.

The camera accepts 120 and 220 film film with film backs configurable for 6×7 cm, 6×6 cm and 6×4.5 cm exposures. These backs are rotating, allowing for both landscape and portrait orientation without removing the back. Special-purpose backs allow for the use of Polaroid film as well as Quadra 72 4×5 sheet film. Mamiya RB67 backs are also supported via the G-Adapter. The film speed is set on each RZ back via a dial. There are two versions of the 6×7 and 6×4.5 backs. The model II versions have a second film counter to always show the film count on the top, regardless of the back orientation.

The RZ67 operates on one 6V 4SR44 silver oxide battery, or 6V 4LR44 alkaline battery. It

The RB67 Professional was introduced in 1970 with a similar look to popular medium format SLR cameras like the Hasselblad V series, but was larger due to the larger 6×7 cm frame size. However, the RB67 differed visually from other medium format cameras of the time, which resemble very large 35mm cameras.[3]: 168  The RB67 is a modular camera system. This means lenses, viewfinders, ground glass, and film backs are interchangeable. There is no focal plane shutter in the RB67. The RB67's Sekor lenses have mechanical leaf shutters which are cocked on the body and triggered either from a threaded shutter release on the lens or from the body's shutter button. Focusing is performed with bellows on the body. Though the RB67 is a completely mechanical camera there are a variety of motorized film backs and automatic exposure finders that do require batteries.
