Sigma added stabilization to one of its most popular zooms. AF is quick, if not quiet, and the glass is sharp at all but the longest focal lengths. By far the least expensive stabilized lens in this class.
Talk about popular: In mid-February, Sigma was offering three different versions of a 70–300mm f/4–5.6 full-frame zoom, including this new Optically Stabilized model ($400, street). It’s one of the few zooms that let Sony and Pentax shooters choose between lens-based and camerabased stabilization.
