Optical Performance
Renowned as the world’s fastest 400mm lens at its 1981 launch, it uses Super Spectra Coating (S.S.C.) for flare resistance and sharp, high-contrast images even wide open. The rear-group focusing system keeps the barrel length constant, aiding precise handling on tripods for sports, wildlife, or astronomy.
Build and Handling
Built like a tank with a tripod collar and bag-style case, its heft demands a sturdy mount—perfect for pros but challenging handheld. It supports auto-aperture metering on Canon FD bodies, with smooth preset focusing for fast subjects.
Ideal Applications
Excels in wildlife, sports, portraits, and astrophotography on full-frame film or adapted mirrorless bodies (via FD-EF or FD adapters). Vintage users love its creamy bokeh and character; modern shooters adapt it for video or creative looks. Pairs well with teleconverters for 560mm+ reach.
Comes with FD-EF adapter and lens hood.
