An everyday utility zoom, with image stabilization, and 1:2.2 magnification for close-ups, it weighs less than most f/2.8 lenses.
An upgrade of Sigma’s digital-only macro lens (the 17–70mm f/2.8–4.5), this large-aperture standard zoom ($450, street) adds a tad more speed, another aspheric element (for a total of three), on-board image stabilization, and several ounces more in weight.
A 27–112mm equivalent on most cameras that have APS-C sized sensors, this is among the few lenses that give Sony and Pentax shooters their choice of image stabilization systems: lens- or sensor-based.
