The Bronica ETRSi was manufactured from 1989 to 2004. It is the last of the Bronica ETR models. The first model, the ETR, was released in 1976. Later, in 1977, the ETRC was released and in 1979 the ETRS. Accessories range includes the Waist-Level Finder, Prism Finder-E, AE-III Prism Finder-E (metered), Rotary Viewfinder-E, several interchangeable Focusing Screens, Motor Winder-Ei, Speed Grip-E and backs for 120, 220, 35mm, 35mm panoramic and Polaroid. Lenses for the Bronica ETRSi are: Zenzanon-PE 40mm f/4, Zenzanon-PE 50mm f/2.8, Zenzanon-PE 60mm f/2.8, Zenzanon-PE 75mm f/2.8, Zenzanon-PE Macro 100mm f/4, Zenzanon-PE 135mm f/4, Zenzanon-PE 150mm f/3.5, Zenzanon-PE 180mm f/4.5, Zenzanon-PE 200mm f/4.5, Zenzanon-PE 250mm f/5.6 and Zenzanon-PE 500mm f/8.
I got my ETRS system in about 1988 in a trade for a fairly extensive 35mm and 1.2 frame camera collection wanted by the photo dealer. It was about 6 months old and owned by a son of the owner of a local newspaper. Much of the system was still in original boxes and appeared not used.
It feels rock solid and with the modular system, seems to be configurable to just about what anyone could feel comfortable with. MC lenses have been panned by some when compared to the late formulations and competitor’s lenses but in my experience, the lenses are excellent.,
I have used the camera for all types of professional shooting and it has never failed me or skipped a beat. The lenses are all late MC lenses and are the E series. Very sharp. I've got a 35mm back and using it as 35mm camera, I've gone up against the likes of Nikon, Leica, and Canon in slide competitions and never felt the lenses held me back. With the speed grip and AEII metered finder, it feels and handles just like a 35mm SLR and is not heavier than a number of total 35mm cameras and very close to my Olympus DSLR. No a lightweight but, not as heavy as one might expect.
The leaf shutter in lens means if a shutter should freeze while out, all is not lost, just swap lenses. The AE finder is accurate and never failed to dial in quite close to my hand held meter. Most of the lenses have the same filter size, a big plus as filters, especially polarizers can be quite expensive space takers adding weight in the field.
Over the years I have a love/hate relationship with Bronica cameras. But putting all that aside I went into shooting the ETRS with an open mind and discovered a rather fun camera. When it comes to 645 cameras, the ETRS is the real underdog while the Mamiya m645 and to a lesser extent the Pentax 645 get most of the glory. Which to people looking to crack into medium format the ETR line of cameras offers you the most bang for your buck if you’re just getting started.
