The ETR line started 1976. The ETRS (1979) added refinements; the ETRSi (1989) added TTL flash metering, multi-exposure, and improved electronics. Production ran 15 years until 2004 with Tamron's Bronica brand closure. The Zenzanon-PE lens series — sharp, multi-coated, leaf-shuttered — accompanied the ETRSi.
For wedding photographers who needed medium-format leaf-shutter sync for fill-flash but wanted a smaller, lighter body than a Hasselblad, the ETRSi was the workhorse. The 6×4.5 negative — slightly smaller than 6×6 — lets the body and lenses be physically smaller. With AE prism, motor winder, and grip, the ETRSi handles like an oversized 35mm SLR.
For 2026 buyers, the ETRSi is the cheapest entry into modular medium-format with leaf shutters — a clean ETRSi + 75/2.8 PE + 120 back + AE prism runs $500–800. The Zenzanon-PE 75/2.8 is excellent. Trade-off: 6×4.5 is the smallest medium-format frame; not as scannable to massive prints as 6×7 or 6×9.
Zenzanon-PE lenses (electronic leaf): 40/4 PE, 50/2.8 PE, 75/2.8 PE (kit), 105/3.5 PE, 150/3.5 PE, 200/4.5 PE, 250/5.6 PE, plus a 105/4.5 macro. Backs: 120, 220, Polaroid, 35mm panoramic. Finders: waist-level (default), AE-III prism (TTL meter), rotary prism. Speed Grip-E (vertical grip), Motor Drive E (1.5 fps), TTL Flash 30 / 32.
