The Olympus OM-3 is a mechanical 35mm SLR in the OM system, introduced in 1983 as a manual-exposure companion to the automatic OM-4. It uses a horizontal-travel mechanical shutter and includes the multi-spot metering system also found on the OM-4, positioning it in the 1980s as a specialist metering-focused body for working photographers. A later titanium variant, the OM-3Ti, was offered as a premium version of the same body.

At recent UK auction, hammer prices for the OM-3 have spanned roughly £270 to £1,100, reflecting the gap between a standard chrome OM-3 and the scarcer OM-3Ti variant. With only a small number of saleroom results on record, the market in 2026 remains thin and condition-sensitive — a clean, fully functional titanium example is what drives the upper end of what this camera is worth, while a tired standard body sells for considerably less. Buyers should expect the price a specific OM-3 fetches at auction to swing sharply on cosmetics, shutter accuracy and whether the meter is working.
