A fast, stabilised, medium-telephoto lens that can be used with ‘full frame’ and APS-C sensor DSLR cameras and supports hand-held shooting in low light situations.Sigma has been producing fast tele zoom lenses for hand-held photography since the late 1980s and, although the new 70-200mm f/2.8 APO EX DG OS lens claims to be a second generation model, we estimate it’s the sixth in a line that reaches back to the original AF 70-210mm f/2.8, which was designed for 35mm film SLR cameras. Interestingly, the main difference between the new lens and its immediate predecessor is the addition of the company’s Optical Stabilisation (OS) system.
