The Canon EF is a 35mm film SLR introduced in 1973, using the Canon FD lens mount. It was positioned as an advanced enthusiast and semi-professional body, sitting below the F-1 in the range, and is sometimes nicknamed the "Black Beauty" for its all-black finish.

At recent UK auction, hammer prices for the Canon EF have ranged from around £40 to £500, with a median closer to £56 — these are saleroom results (wholesale, before commission), not dealer retail. The wide spread in 2026 reflects how condition-sensitive this model is: tidy, fully working bodies sell for substantially more than the cosmetically tired examples that make up most of the market, and an outlier clean example can push what the camera is worth well above typical levels.
