  • ETR SP: Matching body, 120 back, and 75mm MC lens in black metal or silver chrome. All three components have "SP" designation, but otherwise seem identical to standard issue ETR parts.
  • 20th Anniversary ETRS (probably 1979): Matching body, 120 back, and AE-II finder in black painted metal with brown leather.[2]
  • ETRS Clubman (perhaps 1980 with the introduction of the SQ system): Matching body and AE-II finder in black painted metal, silver Clubman name plates, and lower rubber side panel reminescent of the newly introduced Bronica SQ camera system.
  • Safari ETRS (sometime between 1982 and 1988): a surprisingly complete color-coordinated system with ETRS body, 75mm lens, 120 E back, AE-II finder, waist-level finder, speed grip, professional lens hood, and system case in green (possibly painted) polycarbonate with tan leather and accents. [3]
  • Transparent Display ETRSi (likely made for the introduction of the ETRSi in 1989): Matching body and 120 back in transparent polycarbonate with no leather covering.[4]
  • “William Fox Talbot the 150th Anniversary Special Edition” ETRSi (1990): Standard black polycarbonate ETRSi body with gold plaque below the shutter speed dial. Also came with Billingham Talbot 150 Year Hard Equipment Case (Holds Body, 2 Backs, 3 Lenses, Flash, Finder, and Motor Grip)

Chrome bodies and accessories Edit

Throughout the life of the ETR line Bronica kept producing chrome bodies and backs, starting from the introduction in 1976. They made chrome ETR and ETRS bodies and chrome 120, 220, and 70mm backs probably until 1981 when they switched from metal body panels to polycarbonate. Then in 1996 they produced the Limited Edition chrome ETR-Si body and matching chrome Ei 120 back. The original chrome ETR and ETRS bodies came with chrome winding cranks, while the 1996 Limited ETRSi came with a standard black crank. Also the ETR and ETRS backs had chrome shells/frames and chrome inserts, while the 1996 chrome 120 backs had a standard black painted shell with a chrome insert.

An ETR manual that shows the original chrome components of the system is available online.[6]

There were never any chrome metal finders, though most of the pre-1981 finders seem to have been black painted metal just like the standard black bodies.

Confusingly, there was a later, champagne chrome colored polycarbonate 40th Anniversary edition that did have its own matching AE-III Finder, Speed Grip, and 75mm lens. This set uses grey instead of black leatherette. It is very pretty (and Bronica used its great original type and logo from the 60s)-- but it does not match any previous silver chrome components.

Original ETR and ETRS chrome bodies, backs, and cranks all look good and work well together with the other standard black components and the 1996 chrome Special Edition.[7]

One can replace the black plastic ME and MLU levers and the whole winder cover of the 1996 edition with metal chrome versions scavenged from any black metal paint ETR or early ETRS parts bodies. Doing so makes a thoroughly modern ETRSi body reminiscent of the Bronica S and S2 series -- and more importantly gives a very rugged, compact, modern medium format body.
