Canon's FD-mount 28mm wide prime — classic manual-focus design for Canon film SLRs.
The Canon FD 28mm f/2.8 is a manual-focus wide-angle prime for Canon's FD-mount film SLR system. The FD mount predated the EF mount — FD lenses do not mount on modern Canon EOS cameras without adapters that compromise quality.
Optically good — sharp from f/5.6 with the 28mm providing useful wide-angle coverage for film photography. FD-mount optics are generally well-regarded. Manual focus with Canon's FD breech-lock or later New FD bayonet. SSC (Super Spectra Coating) on later versions.
Canon FD mount with 55mm filter thread. Compact and lightweight. Manual focus and aperture. Breech-lock or New FD bayonet depending on version. FD mount is not compatible with Canon EOS without quality-reducing adapters.
Available used very cheaply. FD lenses do not adapt well to Canon EOS — the flange distance prevents infinity focus without corrective optics that degrade quality. Adapts better to Sony E, Fuji X, and MFT mirrorless via simple adapters. For film FD-mount users or mirrorless adapter enthusiasts.
