The Ernemann Ermanox 9x12 is a German plate camera from the 1920s, built around a fixed Ernostar lens designed for available-light photography. Its large maximum aperture made it a tool for press and reportage work at a time when most plate cameras were limited to slower optics.

With only a single UK auction-hammer record on file — a £11,000 result in 2019 — there is no meaningful range or median to publish today, and any current value estimate would be speculation. Buyers asking what an Ermanox 9x12 is worth or how much one sells for in 2026 should treat that figure as one historical data point at saleroom level rather than a reliable benchmark, since condition, completeness of the original plate holders and shutter function heavily influence price.
