The Zeiss Ikon Tropen Adoro 230/7 is a tropical-finish folding plate camera, built with teakwood and brass fittings for use in humid climates. It dates from the early decades of the twentieth century, when Zeiss Ikon offered tropical variants of its plate cameras at the upper end of its catalogue.

Auction evidence for this exact model is thin: the only verified UK saleroom record on file is a single Christie's hammer result of £456 from 2005, so any sense of what one is worth today rests on that lone data point. Because that figure is a wholesale auction-hammer price rather than a dealer asking price, retail values in 2026 for a comparable example would typically sit higher, but with only one sale recorded the market price cannot be triangulated with confidence.
