The Zeiss Ikon Donata (227/7) is a folding plate camera from the early 20th-century German tradition, produced by Zeiss Ikon following the 1926 consolidation that brought together makers including Ica, Contessa-Nettel, Ernemann and Goerz. It was positioned as a mid-range folding camera for sheet-film and plate users rather than a premium model.

Auction data for the Donata (227/7) is very thin: a single UK saleroom hammer result from 2011 sells for £160, which is the only verified reference point available today. With just one data point, that figure should be treated as indicative rather than a reliable market price, and condition, completeness of the original plate holders and shutter function will heavily influence what a similar example is worth in 2026.
