Sigma AF 70-200mm f/2.8 EX DG HSM APO macro (Nikon) - Review / Test Report
3 June 2008
Conclusion: The Sigma AF 70-200mm f/2.8 EX DG HSM APO macro is pretty impressive large aperture tele zoom lens. The resolution figures are on a very good to excellent level and neither distortions, vignetting nor CAs are really field relevant on an APS-C DSLR. The bokeh (out-of-focus blur) is pretty smooth and buttery - certainly an important aspect here. The mechanical quality of the lens is excellent and the HSM AF drive is both fast and near silent.
