Overview

The Sigma 16-28mm f/2.8 DG DN Contemporary is a compact, lightweight ultra-wide zoom for full-frame mirrorless, targeting consumers with a lower price than the ART series. Optically, it shows significant barrel distortion at 16mm and high vignetting, but these are largely correctable in-camera. Build quality is solid with smooth zoom and focus rings, internal zoom, and a 72mm filter thread, though weather sealing is minimal. It suits travel, landscape, and vlog photographers who prioritize portability and a constant f/2.8 aperture over extreme wide-angle coverage.
