The Sigma AF 135-400mm f/4.5-5.6 APO DG is a telephoto zoom lens designed for full-frame DSLR systems, with mount options spanning Canon EF, Nikon F, and Sony A. The focal length range runs from 135mm to 400mm, making it a capable choice for telephoto work across a range of subjects and distances. The maximum aperture opens to f/4.5 at the wide end and f/5.6 at the telephoto end, providing reasonable light intake across the zoom range.
Both auto and manual focus are supported, giving photographers the choice of letting the camera drive focus or taking direct control. The lens features a 77mm filter thread, compatible with widely available standard filters. At 1,250g, it is a substantial piece of glass best suited to supported shooting via tripod or monopod.
