Canon 300mm F/2.8 L FD Mount Lens Review

The Canon 300mm f/2.8 L FD is a legacy manual-focus telephoto prime from Canon's pre-EOS era, built for the FD mount system that dominated the brand's lineup through the early 1980s. It features a 48mm drop-in filter holder and, like most L-series glass from the period, a robust metal construction and excellent optical pedigree. At f/2.8, it offers a fast maximum aperture for its focal length, making it well-suited to wildlife, sports, and portraiture in good light, though lack of modern coatings and autofocus mean it demands patience and technique.

This particular unit is sold used in excellent condition and includes the lens hood, a meaningful inclusion given the scarcity of vintage accessories. FD lenses require an adapter to work on modern Canon EF or RF bodies, and adapters with optical elements can degrade image quality or introduce vignetting. The manual focus and stop-down metering workflow will feel archaic to shooters accustomed to modern AF telephoto lenses, but for film photographers shooting FD-mount bodies or digital users looking for characterful vintage glass on a budget, the price point is appealing. Image quality at the center is typically strong, though corner performance and contrast may lag behind current optics.
