The Kochmann Korelle K is a pre-war German rollfilm camera, produced in the 1930s by Franz Kochmann of Dresden. The black-finish version is a small-format folding/strut camera aimed at the enthusiast market of its day.

With only one tracked UK auction hammer result, the Korelle K (black) sold for £434 in November 2020 at saleroom level — a wholesale figure that excludes buyer's and seller's commission. As of today in 2026, that single data point suggests a value in the mid-hundreds for a presentable example, but with so little turnover any current price is indicative rather than firm. Condition, completeness of the original case, and the state of the bellows or shutter will materially affect what an example sells for.
