The Canon FD 100mm f/2 is a fast manual-focus short telephoto prime for the Canon FD mount, a system Canon produced from 1971 until 1987. With its bright f/2 aperture and 100mm focal length, it was designed primarily for portraiture, low-light work, and head-and-shoulders telephoto use on 35mm SLR bodies.

At UK saleroom level the FD 100mm f/2 is a relatively scarce listing, and the single hammer result on file from late 2023 sold for £500, which sits as both the high and the median in the dataset. Because that figure is an auction hammer price rather than a dealer asking price, clean retail copies in 2026 typically sell for more once commission and dealer margin are added. Buyers should treat £500 as a wholesale benchmark for what a usable copy is worth at auction today rather than a guide to what the lens is worth on the shelf.
