    Overview

    The Canon EF 100-300mm f/5.6 L offers good central sharpness when stopped down, but edges are soft at 300mm (PhotographyBLOG). Chromatic aberration and pincushion distortion are noticeable at the long end (PhotographyBLOG). Build quality is mixed: a metal mount and internal USM AF are praised, but the push-pull zoom and coarse focus ring are criticized. It suits budget users seeking L-series optics and fast AF, despite handling quirks.
