This Zenza Bronica ETR 220 Film Back is an interchangeable film back designed for the Bronica ETR medium-format camera system. It is intended for 220 roll film and allows photographers to change film quickly by swapping film backs. The ETR system produces images in the 6 × 4.5 cm format.
A roll of 220 film was designed to provide up to 30 exposures in this format, compared with 15 exposures on 120 film. As 220 film is no longer commonly produced, this film back is particularly interesting for collectors and photographers who still have access to compatible film.
The back is designed for the Zenza Bronica ETR system. Its condition and functionality have not been specified and should be checked before use.
