The Mamiya RZ67 Professional (1982) is the first generation of the RZ67 system — Mamiya's electronically governed answer to the all-mechanical RB67 line. The "RZ" designation signals the new direction: an electronically controlled shutter in each Sekor Z lens (replacing the purely mechanical Seiko shutters of the RB67 Sekor C lenses), a new RZ bayonet mount incompatible with RB lenses, and optional aperture-priority autoexposure via the separately purchased AE Prism Finder. The rotating film back and bellows-based focusing geometry carry over from the RB67 design, giving photographers the same orientation-change workflow without repositioning the camera.

Mamiya launched the RZ67 in 1982 to modernize the 6×7 SLR market that the RB67 had created. The primary commercial driver was studio flash photography: while the RB67 leaf shutters already synced at all speeds, the electronic timing of the RZ67 gave more repeatable exposure consistency, and the AE prism finder opened aperture-priority shooting for location work. The original RZ67 Pro was refined into the RZ67 Pro II (1995), which added half-stop shutter increments, compatibility with the AE Prism Finder FZ (a more capable meter), and improved electronics. The further-refined RZ67 Pro IID (2004) added digital-back interface support.
The original Pro therefore spans approximately 1982 to the mid-1990s. It accepts all Sekor Z lenses and is functionally identical to the Pro II in most studio applications; the main practical differences are the half-stop shutter steps (Pro II only) and the AE Prism Finder FZ compatibility (Pro II / IID only — the original Pro works with the earlier AE Prism Finder PD).
The original RZ67 Pro established the electronic-medium-format-SLR category in Japan and internationally. By coupling precise electronic shutters to a modular back system and a rotating back, it gave commercial photographers the reliability of electronic timing with the flexibility of a fully swappable system. The Sekor Z lens lineup introduced with the original Pro — including the 110/2.8 W and 90/3.5 W — set the optical standard that remained through the entire RZ67 system's production life.
For buyers in 2026, the original Pro is the most affordable entry into the RZ67 system. It lacks half-stop shutter increments and AE Prism Finder FZ compatibility, but it accepts every Sekor Z lens ever made, and the fundamental 6×7 negative quality is identical. It is a working studio camera, not merely a collectible.
Mamiya RZ bayonet mount. All Sekor Z lenses are compatible (leaf shutter in each lens): 37/4.5 fisheye, 50/4.5 W, 65/4 W, 75/3.5 W shift, 90/3.5 W, 110/2.8 W, 127/3.8, 140/4.5 W macro, 150/3.5 W, 180/4.5, 250/4.5 W APO, 360/6. The original Pro accepts the earlier AE Prism Finder PD (not the FZ finder of the Pro II). Film backs: 120, 220, Polaroid, 6×4.5.
