The Canon L-3 is a 35mm rangefinder camera using the Leica thread mount (also known as Canon's screwmount rangefinder system). It sits within Canon's late-1950s rangefinder line, positioned below the top-tier L-models as a more accessible screwmount body.

At UK auction in recent years, hammer prices for the Canon L-3 have ranged from about £90 to £300, with only a small number of recorded sales to draw on. As of 2026 the value of any individual example is highly condition-dependent, and the thin sales record means a single clean body can sell for materially more than a worn one — buyers asking what an L-3 is worth today should treat the wholesale saleroom range as a guide rather than a firm price.
