The Certo Durata is a prototype camera attributed to the German maker Certo, a Dresden-based manufacturer active in the 20th century. As a prototype rather than a series-production model, it exists in very limited numbers and was not part of Certo's regular catalogue.

Auction evidence for the Durata is extremely thin: a single UK saleroom result from 2014 recorded a hammer price of £200, which gives the only public reference point for what one sells for today. Because this is a wholesale auction figure rather than a retail price, and the sample is one example, the true value in 2026 could fall well outside that figure depending on provenance, condition, and bidder interest on the day.
