The E. Krauss Photo-Revolver is an early specialist still camera produced by the French maker E. Krauss. It is a niche piece aimed at collectors of unusual photographic apparatus rather than a general-purpose model.

Sales data for the Photo-Revolver is extremely thin: a single recorded UK auction hammer result from December 2009 stands at £800, which is wholesale rather than a retail or dealer asking price. With only one data point, there is no reliable range or median to publish, and as of 2026 today's value would depend heavily on condition, completeness and bidder interest on the day. Anyone trying to gauge what one is worth or what one sells for should treat that figure as indicative only.
