Overview

The Canon FL 55-135mm f/3.5 is a well-regarded vintage zoom lens praised for sharpness and excellent image quality throughout its range, especially at f/5.6 and above, where it rivals period primes. Its main weaknesses are a close focus of 7 feet and heavy weight near 2 lbs, though a built-in tripod mount aids handling. Build quality is high with an automatic diaphragm and aperture preview. It suits FL mount users, particularly for portraits; FD users are advised to consider the lighter nFD 50-135mm f/3.5 instead.
