70–200mm · f/2.8
The Sigma 70-200mm F2.8 EX DG Macro HSM II offers a cost-effective alternative to premium telephoto zooms, with solid build, fast autofocus, and a useful macro mode. However, multiple reviewers report severe quality control issues, including front-focus problems and internal debris. Optically, it shows improved resolution and chromatic aberration over its predecessor but still lags behind Canon and Nikon equivalents in homogeneity. It suits budget-conscious users willing to gamble on sample variation, but the stabilized 2010 version is recommended for better image quality.
