The Marion Perfection is a British-made plate camera from Marion & Co. of London, a 19th-century maker of wooden field and studio cameras. It was sold under the Perfection name as a folding plate camera for glass-plate photography.

Sales data for the Marion Perfection is extremely thin, so any guide to what one is worth today must be read with caution. The single recorded UK auction hammer result stands at £129, achieved at Christie's in July 2000, which gives an indicative wholesale value rather than a current retail price. With only one data point, the price a clean example sells for in 2026 will depend heavily on completeness, condition of the bellows and woodwork, and whether original plate holders are present.
