Overview

The Sigma 105mm F2.8 EX DG Macro is a well-built, solid lens offering true 1:1 magnification and good working distance for macro. Optically, it delivers very sharp images with well-controlled chromatic aberrations and good color correction. Weaknesses include a slow autofocus and a non-rotating but extending barrel that requires care at close distances. It suits macro and portrait photographers seeking excellent value, especially on a budget, though it lacks weather sealing and a tripod collar.
