ETRS, second type (polycarbonate shell) Bronica ETR — — Not published. camera-wiki's table gives '1982?' to 1989.09; Tamron's discontinued-products list ends the ETRS in September 1989
ETRS 20th Anniversary Bronica ETR — — No number published (Japanese Wikipedia gives none)

  1. Weight: 465 g is the body without battery, 1,280 g the standard set without battery (Tamron). Neil Piper weighs a body at 'a shade over 0.5kg' and his kit with winder, AE-II and 50mm at about 1.9 kg; DustyGrain's '940 g body' (search snippet, not read) does not match any published figure and is not carried.
  2. Battery: Tamron lists one 6 V alkaline or silver cell; Piper writes PX28A or 4LR44. Battery check is a button lighting a red LED in the finder, where the ETR used a green LED on the top plate.
  3. Dates: Tamron's discontinued-products list ends the ETRS in September 1989; the ETRSi had been on sale since December 1988. Piper's text says 'early 1979 I believe' against his own FAQ's October 1978; October 1978 is what Japanese Wikipedia and camera-wiki give.
How to tell them apart (expand)
  • 'ETRS' on the nameplate. Metal panels with a round front lens-release button mark the first type; a polycarbonate shell with a rectangular slider on the side marks the second. The ETRSi returned the release to the front and adds a mirror-lock-up lever and an SCA socket
  • Eyelet strap lugs and a three-position release lock, against the ETR's spring-catch studs and plain button (camera-wiki)
  • Red battery-check LED inside the finder (Tamron)
  • No B on the speed dial: T only. B arrived with the ETRSi
  • Listing trap: 'ETRS' is also written for ETRSi bodies, and sellers drop the i; the ETRSi has 'ETRSi' on the plate and grey locking dark slides on its Ei backs

ETRS, first type (metal panels):

  • Metal body panels as on the ETR, with the round lens-release button still on the front of the body (camera-wiki)
  • Eyelet strap lugs in place of the ETR's spring-catch studs, and a three-position lock on the release button: free, body release locked with winder and cable release live, all locked (camera-wiki)
  • Extra electronic contact in the finder bay for the AE-II and AE-III finders (camera-wiki)
  • Chrome version with chrome backs offered until about 1981 (camera-wiki)

ETRS, second type (polycarbonate shell):

  • Polycarbonate outer shell; the lens release moved from a round button on the front to a rectangular slider on the side of the body (camera-wiki)
  • Backs with two latch tabs (camera-wiki)

ETRS 20th Anniversary:

  • Black painted metal body with brown leather; sold with a matching 120 back and AE-II finder (camera-wiki)

ETRS Clubman:

  • Silver 'Clubman' nameplates and a lower rubber side panel on a black painted metal body (camera-wiki)

ETRS SF (Safari):

  • Green polycarbonate shell (camera-wiki: 'possibly painted') with tan leather; polycarbonate, so a second-type body
  • Sold as a set: 75mm lens, 120 E back, AE-II finder, waist-level finder, speed grip and case (camera-wiki)

Tamron's ETRS sheet says only that finders interchange; the magnifier and coverage figures are the ETR's (4.03×, 1.25× with the 75mm, 96 × 94%), repeated on the ETRC sheet, and the finder is the same part.

The AE-II and the later AE-III use a contact added to the ETRS body and are not fully compatible with the ETR (camera-wiki). The first-type AE finder, a plain prism, a rotary finder and a sports finder are also listed for the system.

Where sources disagree

First
  • '1982?' — camera-wiki's model table, with its own question mark
  • around 1981 — camera-wiki's statement that chrome-body production switched to polycarbonate about then

Both from one page. No source gives a firm year for the polycarbonate ETRS, so the variant carries no start date.

What reviewers say

History

The ETRS of October 1978 is the ETR with its handling sorted out. The shutter, the 55.1 × 42.5 mm frame and the four-claw bayonet are unchanged; what Japanese Wikipedia calls improved mechanisms and operation shows up on the outside as eyelet strap lugs, a three-position lock on the release button and a contact in the finder bay for the new AE-II prism, whose readout appears on a half-press. Tamron’s spec sheet lists the body at 465 g and the standard set, body, ETRS 120 back, 75mm lens and waist-level finder, at 1,280 g and ¥153,000, two thousand yen less than the ETR’s set two years earlier. Backs for 35mm film and Polaroid pack film joined the 120, 220 and 70mm ones.

Two bodies carry the name. The first keeps the ETR’s metal panels and round front lens-release button and was offered in chrome as well as black until about 1981; the second, which camera-wiki dates from around 1982 with a question mark, has a polycarbonate shell and a rectangular lens-release slider on the side. The second body is the basis of the ETRSi, which put the release back on the front. Three limited sets sit alongside: a 20th Anniversary camera in black paint and brown leather with an AE-II finder (probably 1979), the 300-set Clubman with silver nameplates and rubber side panels (about 1980), and the green-and-tan ETRS SF safari set sold some time between 1982 and 1988. Tamron’s list ends the ETRS in September 1989, nine months after the ETRSi arrived.

Reviewers agree on what it is. Wayne Lorimer at Kosmo Foto made it his landscape camera and admits “it ain’t no featherweight”; Neil Piper at Emulsive calls it “a freakin’ tank” and means it kindly, weighing his kit with winder, AE-II and 50mm at about 1.9 kg; Andy at 35mmc finds the bare body lighter than a Mamiya 645 but the brick shape no help for handholding without a grip. All three bought in cheaply, and Lorimer repeats the “poor man’s Hasselblad” tag that follows the line. Without a battery the camera still fires at 1/500, which is the one thing it does on its own; everything else, from the AE finder to the 8-second slow end, needs the 6 V cell.
