Used Bronica ETRS 120 Film Back

Finally got around to testing this back and the dark slide mechanism is smooth, no light leaks on my first roll. It's a solid, working piece for anyone wanting to swap films quickly on the ETRS.

Shot a roll of Portra with this back and the frame spacing is perfectly consistent. Feels solid and the dark slide mechanism works smoothly without jamming. Exactly what my Bronica needed.

Switched to this back for my ETRS and the dark slide slides in and out with a satisfying click, no light leaks so far. The winding mechanism feels smooth and consistent, exactly what I needed for street shooting.
