The Kirn Fingerprint Camera is a specialist British-made instrument designed for capturing fingerprint impressions, used historically in forensic and identification work rather than general photography. It sits outside the consumer camera market as a piece of dedicated investigative equipment.

Sales data for the Kirn Fingerprint Camera is very thin, with one UK auction hammer result of £312 recorded in January 2025 — a wholesale saleroom figure rather than a retail price. On that limited basis, today a clean example sells for roughly that level, though the value of any individual unit is highly condition-sensitive and the market is too sparse to define a reliable range.
