    Overview

    The Canon Zoom FD 100-300mm f/5.6 (L and non-L versions) is a compact 3x telephoto zoom with a macro function offering 1:3 reproduction at 200mm. The L version uses one fluorite and one UD element to minimize chromatic aberrations and purple fringing, delivering good sharpness from 100-200mm, but performance at 300mm is inconsistent—some users find it soft, possibly due to short focus throw. Build is light (710g L, 880g non-L) with a push-pull zoom. It suits hikers and macro enthusiasts on a budget, but may frustrate those needing consistent sharpness at the long end.
