Zenza Bronica Bronica ETRSi
The Bronica ETRSi is a 6x4.5 medium format SLR introduced by Zenza Bronica in 1988 as part of the ETR modular system. It accepts interchangeable film backs, viewfinders and lenses, and was positioned as a working professional's camera for weddings, portraiture and studio use.
At recent UK auction, hammer prices for the Bronica ETRSi body (often sold with a standard lens and back) have ranged from about £88 to £470, with a median around £330 as of today. Condition, completeness of the kit, and whether the finder and 120 back are present drive most of the spread — tired or incomplete examples sell for well under £200 at saleroom level, while clean working outfits comfortably fetch £340 and up.
Sales History
Prices shown are realised prices — auction results and completed eBay sales, never asking prices. Most saleroom figures are hammer prices, before commission; some houses publish a premium-inclusive figure, and we do not adjust for condition. Dealer and retail asking prices are typically higher.
