Canon's FD supertele — the 400mm f/4.5 S.S.C. with Super Spectra Coating.
The Canon FD 400mm f/4.5 S.S.C. was a supertelephoto prime in the first FD generation, offered from 1975 with Super Spectra Coating. It provided a moderate-aperture 400mm that was more portable and affordable than the fast f/2.8, serving wildlife and sports photographers needing long reach.
This is a manual-focus Canon FD lens with a fixed 400mm focal length and a maximum aperture of f/4.5. It carries Canon's Super Spectra multi-coating and is a tripod-collar supertelephoto with focus and aperture set manually on the barrel. The moderate aperture keeps the lens manageable for its reach.
A 400mm f/4.5 delivers strong telephoto reach for distant wildlife, field sport and compressed landscapes while remaining lighter than a fast supertelephoto. Its aperture suits daylight action, and the long focal length compresses perspective and isolates subjects against distant backgrounds.
On the used market the FD 400mm f/4.5 S.S.C. is a practical long telephoto valued for its balance of reach and portability. Inspect the elements for haze, fungus and separation, confirm the aperture blades are clean and dry, and test the focus helicoid for smoothness. Check the tripod collar and hood, and note it adapts to mirrorless via an optics-free FD adapter.
