Canon FD 500mm f/8 Reflex - Canon FD Mount

The Canon FD 500mm f/8 Reflex is a compact catadioptric (mirror) lens, offering significant telephoto reach in a fraction of the size of a conventional 500mm lens. It features the characteristic 'doughnut' bokeh common to mirror designs and a fixed f/8 aperture. It is a lightweight solution for birding or surveillance where carrying a traditional super-telephoto lens is impractical. Secondary market buyers should carefully inspect the mirror coatings for any signs of degradation or 'silvering' issues. Because mirror lenses are sensitive to alignment, we check for any evidence of impact that might have shifted internal components. SDS examines the focus ring for smooth operation and confirms the rear-mounted filter system is present and intact, as these are often missing.
