Gamma Duflex
The Gamma Duflex is a 35mm film camera produced in Italy in the mid-20th century. It was a niche domestic-market model rather than a mass-produced export product, which contributes to its scarcity today.
At recent UK auction, hammer prices for the Gamma Duflex have ranged from roughly £2,400 to £4,000, with a median around £3,800. These are wholesale saleroom results, and as of 2026 the Duflex remains a collector-driven camera where condition, completeness and provenance strongly influence what it sells for.
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.
