The Olympus OM-20 is a 35mm SLR from the OM-series of compact manual-focus film cameras. It sat in the consumer tier of the OM line when introduced in the early 1980s, offering aperture-priority automation alongside manual control.

Sales evidence for the OM-20 is thin: a single UK auction hammer result of £69 in January 2025 is the only data point available, so a reliable median or range cannot yet be established. Today that figure should be treated as indicative rather than definitive of what the body is worth at saleroom level, and condition, working meter and included lens will heavily influence the price a clean example sells for.
