Bronica ETRSi6×4.5 Medium Format, Zenzanon 75mm f/2.8

The Bronica ETRSi, introduced in 1989, was the final evolution of Bronica's 6×4.5 medium format system. Its compact size relative to 6×6 and 6×7 cameras, combined with excellent Zenzanon 75mm f/2.8 optics and interchangeable film backs, made it a practical choice for wedding and portrait photographers. The 6×4.5 format offered a good balance between medium-format quality and the ability to shoot more frames per roll.

RetroCam recreates this look using real optical data: color temperature curves, aberration profiles, grain structure, and tonal response. The result is a live camera effect that feels authentic, not just a filter slapped on top.
