The RB67 Pro-S (1974) added incremental refinements to the original 1970 RB67 — most notably an **improved multi-exposure interlock** that lets you decouple the body's wind sequence to make multiple exposures on a single frame, and a brighter focusing screen. The body remained mechanical, the rotating back unchanged, and the bellows focus unchanged. Same Seiko leaf shutters in each lens, same flash sync at all speeds, same 2.7 kg weight.

Released 1974 as the mid-life refresh of the original RB67. The Pro-S ran 16 years until the Pro-SD (1990, refined K/L lenses, slightly larger throat) replaced it. Together with the original Pro and the later Pro-SD, the RB67 line spanned 35 years — among the longest-running medium-format SLR designs.
The Pro-S is the most-recommended RB67 variant for users buying today. The improved multi-exposure interlock makes it more flexible than the Pro, and it's significantly cheaper than the Pro-SD (which has slightly newer lenses but otherwise the same workflow). Most "Mamiya RB67" listings on the used market are Pro-S bodies.
For 2026 buyers, RB67 Pro-S + 90mm f/3.8 C + 120 back at $700–1,000 is one of the cheapest entries into 6×7 studio photography. The trade-off is weight (2.7 kg loaded) and the all-mechanical, no-meter, no-AE workflow.
Mamiya-Sekor C lenses (1970+, mainline). Common: 90/3.8 C (kit), 50/4.5 C, 65/4.5 C, 127/3.8 C, 180/4.5 C, 250/4.5 C. Pro-SD bodies accept the K/L lens series. Same backs and finders as RB67 Pro / RB67 Pro-SD.
