The Corfield Periflex (original) is a 35mm film camera from the British maker K.G. Corfield, introduced in the 1950s. It was distinctive for using a periscope-style focusing device that was lowered through the top of the body to view the image on the film plane, rather than a conventional reflex mirror or rangefinder.

Sales data for the original Periflex is thin, but a 2024 UK auction hammer result of £125 gives a reference point for what a working example sells for at saleroom level today. With only a single recorded result, the wider value range is hard to pin down and condition will heavily influence what any given camera is worth.
