The Zenza Bronica ETRS is a Japanese medium-format SLR that exposes 6×4.5 cm frames on 120 roll film. It is a modular system camera with interchangeable lenses, film backs and viewfinders, positioned as a professional tool for studio, wedding and location work.

At recent UK auction, hammer prices for ETRS bodies and outfits have ranged from about £280 to £480, with the two recorded sales in our data sitting at £275 and £475 and a midpoint around £375. Because these are saleroom wholesale results rather than retail asking prices, what a clean ETRS is worth today in a dealer window will typically sit above this band, and condition, included lens and working film-back seals heavily influence how much each example sells for.
