The Minox III is a subminiature film camera using the 8×11mm Minox format, introduced in the early 1950s as a successor to the earlier Minox Riga and II models. Small enough to be carried in a pocket, it was positioned as a precision miniature camera for discreet photography and general compact use.

UK auction hammer results for the Minox III are thin, with the two recorded sales spanning £140–£550 (wholesale saleroom prices, excluding buyer's and seller's commission), giving a midpoint around £340. As of today in 2026, what a Minox III sells for depends heavily on cosmetic condition, the presence of the original chain and case, and whether the shutter still fires accurately across all speeds.
