The Canon FD 100-300mm f/5.6 is a manual-focus telephoto zoom from Canon's New FD lineup, offering a long, flexible range in a single lens. It was designed for photographers using cameras like the AE-1 Program, A-1 and New F-1 who wanted serious telephoto reach without carrying several primes. Today it is appreciated both by FD film shooters and by those adapting lenses to digital cameras.

A constant f/5.6 maximum aperture keeps exposure consistent throughout the zoom range, which is convenient for manual exposure and metered shooting alike. Canon's multi-coating helps maintain contrast and color saturation, even in bright outdoor conditions. Stopped down slightly, the lens produces sharp, well-defined images with natural color rendering.

Constructed in the solid style of the New FD series, the lens features metal construction, a smooth zoom action and precise manual focusing. The New FD bayonet-style mounting makes changing lenses quick and secure. Its handling is well balanced for a lens of this range, especially on bodies with a motor drive or winder.

The 100–300mm range covers moderate to long telephoto, allowing you to frame portraits tightly at 100mm and reach distant subjects at 300mm. The 58mm filter size is common and affordable. With its relatively modest maximum aperture, the lens remains more compact and lighter than faster telephoto zooms.

This lens is well suited for wildlife, birds, outdoor sports, airshows and landscape details, where telephoto compression creates powerful compositions. It also works well for candid portraits at a distance and for isolating architectural elements in travel photography. Its long reach opens up many creative possibilities.

The lens mounts on all Canon FD-mount cameras, including the F-1, New F-1, AE-1, AE-1 Program, A-1, AV-1 and T-series bodies. With an FD adapter, it can also be used on Sony E, Fujifilm X, Canon RF, Nikon Z, Micro Four Thirds and L-mount mirrorless cameras. On APS-C or Micro Four Thirds bodies, the effective focal length becomes even longer, which is a bonus for wildlife and sports.

Telephoto zooms like this one remain valued because they provide flexible reach and classic build quality at an accessible price. Many video shooters also enjoy using FD lenses for their smooth manual operation and pleasing rendering. It is a practical way to add telephoto capability to a film or adapted digital kit.

If you want a versatile manual telephoto zoom for your Canon FD camera or mirrorless system, the Canon FD 100-300mm f/5.6 is an excellent choice. It combines useful reach, constant aperture convenience and dependable Canon construction. It is a lens that can bring distant subjects within easy reach.
