How to tell them apart (expand)
  • Bellows focusing with a large knob on each side and a rack-and-pinion 46mm extension; no helicoid on the lenses
  • Revolving back: the holder turns 90° on the body for vertical or horizontal format
  • Breech-lock bayonet ring on the lens; leaf shutter with the speed ring on the lens barrel
  • No battery anywhere; an RZ67 has a battery chamber and an electronic speed dial on the body
  • Suffix on the nameplate: none, S or SD

RB67 Professional:

  • Nameplate reads RB67 PROFESSIONAL with no S or SD suffix
  • No format index in the finder interlocked to the revolving back, no focusing-knob lock and no double-exposure interlock on the holder (Photrio thread; photoethnography)
  • Waist-level hood is not the one-touch self-erecting type introduced with the Pro-S (Japanese Wikipedia)

RB67 Pro-S:

  • Nameplate reads RB67 PROFESSIONAL S; the revolving adapter is marked for the Pro-S
  • Horizontal-format index lines in the finder that swing in as the back is turned, driven by the revolving adapter (Pro-S manual)
  • Focusing-knob lock and a single-action self-erecting focusing hood with a double lock (Pro-S manual)

RB67 Pro-SD:

  • Nameplate reads RB67 PROFESSIONAL SD
  • Lens throat enlarged from 54mm to 61mm, the same as the RZ67, so the KL 75mm shift and 500mm APO mount (Pro-SD manual; Photrio thread)
  • Body back built for the 6×8 power-drive magazine (Pro-SD manual)
  • Pro-SD 120 roll film holder with a dark-slide storing lug and memo clip; waist-level finder magnifier 3× against the Pro-S's 2.5× (Pro-SD and Pro-S manuals)

Serial-range notes

Two-letter gold sticker
Mamiya date codes are a small gold sticker on body or lens: first letter the year, second the month, A–J for 1961–70 and again 1971–80, A–T for 1981–2000. The code repeats each decade, so the model tells you which decade (Mamiya Repair).

What reviewers say

History

The RB67 is a 6×7 single-lens reflex built around two ideas that were new together in 1970: a film back that turns 90° on the body so the camera never has to be tipped on its side, and focusing by a bellows on the body rather than a helicoid on each lens. Rotating Back is what the RB stands for. The lenses carry their own Seiko #1 leaf shutters, 1s to 1/400 and T, with flash at every speed, and the body’s side lever cocks shutter and mirror in one stroke. Nothing in the camera needs a battery. It was made for the studio, and the reviewers who take it outdoors all say the same thing about the weight: the Pro-S manual gives the body with its revolving adapter and hood at 1450g, the holder 450g and the 90mm f/3.8 805g, and Wikipedia’s 2.69kg for the outfit is what you carry.

Three versions cover forty years. The original Professional ran 1970 to 1974. The Pro-S of 1974 added the format index lines in the finder that swing in as the back is turned, a lock on the focusing knob, a one-touch self-erecting hood and, on its new Pro-S roll film holder, an interlock that blocks the release on an exposed frame and the wind on an unexposed one; a lever on the holder overrides it for multiple exposures. Japanese Wikipedia calls the Pro-S the balanced masterpiece of the line, and it sold for sixteen years. The Pro-SD of September 1990 opened the lens throat from 54mm to 61mm, the same as the RZ67, so the KL 75mm shift and 500mm APO could mount, and built the body back for a 6×8 power-drive magazine; its holder gained a lug to store the dark slide, and the hood magnifier went from 2.5× to 3×. The Pro-SD manual splits the weight as body 1050g, adapter 200g, finder 185g, holder 475g and 127mm f/3.5 780g. English Wikipedia ends production in 2010.

Two limited editions rest on Japanese Wikipedia alone: the Professional GL of October 1981, 300 sets in gold-coloured metal and lizard covering with a 127mm f/3.8 GL lens and GL holder, and a Pro-SD Gold of 1990, also 300.

Identification is on the nameplate, which reads RB67 PROFESSIONAL, PROFESSIONAL S or PROFESSIONAL SD. Beyond that, a plain Pro has no focusing-knob lock and no double-exposure interlock; a Pro-SD has the wider throat, visible with the lens off, and takes the two big KL lenses. Everything else interchanges: holders attach through the G-lock revolving adapter on any body, all RB finders fit all three, and Mamiya sold the extension tubes in SD-only and all-RB versions. Date codes are a small gold sticker with two letters, year then month, and because the letters repeat every decade the model has to tell you which decade.

What to check when buying is what the reviewers report. The revolving back and the holders seal with foam, and Don Goodman-Wilson’s note that other users find sticky residue is the usual case for a reseal; the dark slide must be in before a holder will come off, and the Pro-S interlock will refuse to fire if the lower slide lock was left open, which is a feature and not a fault. Work the bellows to full extension for pinholes, cock the lens off the body only with the cocking pin in the right position (the manuals warn that the coupling can jam otherwise), and confirm the multiple-exposure lever returns. The Pro-S is the common one and the cheapest way into the system; the Pro-SD costs more only for the lenses that need it.
