The Canon FD 28mm f/3.5 is a manual-focus wide-angle prime for Canon's FD bayonet system, introduced in the 1970s as an affordable companion to faster 28mm options. It was aimed at FD-mount SLR users who wanted a compact, moderate-aperture wide for landscapes, interiors and general reportage.

UK auction activity for the FD 28mm f/3.5 is thin: the single recorded hammer result in our data sold for £25 in October 2023, which sets both the high and low of the range at saleroom level. As of 2026 that figure is consistent with where budget FD wides typically sell for at UK auction, where hammer prices reflect wholesale levels rather than dealer retail, and clean, fungus-free copies tend to command the upper end of that narrow band.
