CP+ 2011: In a group of releases, Sigma has unveiled an optically stabilized version of its 50-150mm F2.8 fast telephoto zoom for APS-C DSLRS. The 50-150mm f/2.8 EX DG APO OS HSM gives a field-of-view range equivalent to around 75-225mm on a 35mm system, but in a design that is smaller and lighter than full frame 70-200mm F2.8 designs. The latest, 'OS' version is claimed to offer the ability to get stable shots at shutter speeds four stops slower than without it. It features a completely revised optical design with 21 elements in 15 groups.
