Overview

The Sigma 150mm F2.8 EX DG Macro HSM offers excellent sharpness and well-controlled chromatic aberration, with good bokeh and a useful focal length between 100mm and 200mm macros. Its main optical weakness is significant vignetting on full-frame, even stopped down. Build quality is solid but the finish shows wear easily, and the tripod collar can be less smooth than competitors. Autofocus is quiet but can be inconsistent and slow in low light. It suits macro and portrait photographers who prioritize image quality and working distance over AF speed and finish durability.
