    Overview

    The Sigma APO 70-210mm f/2.8 is a fast telephoto zoom praised for very good sharpness throughout the range and to the edges, even wide open. Its main drawback is significant weight, and some users report occasional focus misses or sticky zoom rings. Build quality is rated highly (4.73/5), but contrast may be slightly reduced, possibly due to haze. It suits photographers needing a constant f/2.8 aperture on a budget, willing to accept heft and potential maintenance issues.
