Overview

The Canon FL 135mm f/3.5 is a budget-friendly short telephoto lens with solid build quality, featuring an all-metal body and integrated lens hood. Optically, it shows slight corner vignetting wide open, which clears by f/5.6, and becomes sharp at f/8. The aperture ring has a long throw between f/32 and the A setting, which may confuse some users. It suits photographers seeking an affordable portrait lens for FD-mount systems, though the focal length may overlap with zooms.
