135mm · f/2.5
The Canon FD 135mm f/2.5 S.C. is a vintage manual-focus telephoto lens with a fast f/2.5 aperture, praised for its sturdy all-metal build and smooth focus ring. Optically, it is sharp wide open with smooth bokeh and nice swirl, though single-coating (S.C.) can cause flare in backlit conditions. Vignetting is well-controlled, and distortion is absent. It suits portrait and concert photographers who enjoy manual focus and a classic rendering, offering great value second-hand.
