The Canon FD 70-210mm f/4 is a constant-aperture telephoto zoom for Canon's manual-focus FD mount, which was produced from 1971 until the EF system replaced it in 1987. It was designed as a general-purpose telephoto zoom for SLR users wanting a single lens to cover portrait through medium-tele range on 35mm film.

UK auction data for this lens is thin: a single 2023 hammer result of £10 sits in our records, so the wholesale saleroom level for a worn copy is firmly at the entry tier in 2026. As a guide to what an FD 70-210mm f/4 is worth today, that £10 figure reflects an unverified, lower-condition example at auction; cleaner copies typically sell for more at retail, but we cannot confirm a price range from this sample. Treat the median as indicative only until further sales accumulate.
