Bronica ETRSi: the 645 workhorse that earned its reputation.

The ETRSi shoots 6x4.5cm frames on 120 or 220 film, giving you a negative roughly three times the area of 35mm. That size difference shows up in the final image, finer grain at a given print size, more tonal depth in portraits, and a negative that holds up under serious enlargement. The modular system built around the Bronica ETR mount means backs, finders, and grips can be swapped out to match the job than forcing you to adapt your workflow to the camera.

Released in 1989, this body represents a well-settled point in Bronica's design history. The 645 format threads a practical needle: you get significantly more negative real estate than 35mm without the bulk and slower shooting rhythm of a 6x7 system. On a roll of 120, you'll get 15 frames in the 6x4.5cm format, which is a workable number for methodical shooters who aren't burning through film for the sake of it. The ETR mount system has a solid glass library behind it, and the interchangeable back design lets you load multiple film stocks and switch mid-session. For anyone building a medium format film kit around a proven platform, the ETRSi sits in a category where its track record does the persuading.

Who It's For

Portrait photographers who print large will find the 6x4.5cm negative gives them latitude that 35mm simply can't match at comparable enlargements. Documentary and travel shooters get a manageable 645 body that's lighter than a 6x7 system but still delivers a substantial negative. Studio photographers benefit from the interchangeable back system, which allows swapping between film stocks or speeds without finishing a roll. Film photographers returning to medium format after a break will find the ETRSi's modular ETR-mount ecosystem gives them room to grow, different finders, grips, and backs without committing to a new body.

FAQ

What's the practical frame count on a roll of 120 film?
15 frames per roll in 6x4.5cm format, which translates to a deliberate shooting pace without forcing you to reload constantly.
Can you load multiple film stocks at the same time?
Yes. The interchangeable back system lets you load different films and swap them mid-session without resetting the camera.
How does 6x4.5cm compare to 35mm in terms of negative size?
The 645 frame is roughly three times the area of 35mm, which shows up as finer grain at given print sizes and better enlargement potential.
Is the ETRSi a modular system?
The Bronica ETR mount is fully modular. Backs, viewfinders, and grips can be swapped to match different jobs.
What film stocks can this camera use?
Standard 120 or 220 film. The larger negative size works with the full range of color and black-and-white emulsions available in those formats.
Does the 645 format shoot slower than 6x7?
No. The ETRSi maintains a faster shooting rhythm than 6x7 systems while still delivering significantly more tonality and detail than 35mm.
