Overview

The Sigma 24-70mm F2.8 DG DN II Art lens offers excellent optical quality with improved center sharpness from f/2.8, though corners at 24mm are soft at close distances and color fringing appears at the long end. It has high vignetting at wide apertures, requiring auto-correction. Build is robust with weather-sealing, a new aperture ring with de-click, and smooth zoom/focus rings. The HLA AF is fast and silent. It suits general-purpose, travel, and low-light photography, especially for Sony E and L-mount users seeking an affordable f/2.8 zoom.
