    Overview

    The Sigma AF 70-210 mm f/4-5.6 IA-ZOOM is a compact push-pull zoom from the film era, noted for surprising sharpness even wide open, with acceptable corners and good contrast when stopped down. Weaknesses include visible chromatic aberration at the long end, a long minimum focus distance, and a heavy build compared to similar Minolta lenses. It offers quick autofocus in normal use but slow travel to minimum focus. Best suited for budget-conscious photographers seeking a vintage telephoto zoom for full-frame or APS-C, offering decent optical performance at a low cost.
