Excerpt: 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.
Conclusion: The Sigma 17-70mm F2.8-4 DC Macro OS HSM lens is a solid replacement for the 18-55mm that shipped with your camera, but another Sigma zoom is our Editors' Choice.
Pros: Sharp. 4.1x zoom range. 1:2.9 macro magnification. Optical stabilization. Wide aperture. Compact and light. Available for multiple camera systems. Compatibility with Sigma USB dock and mount conversion service.
Summary: Sigma's latest 'C' badged 17-70mm F2.8-4 is an excellent upgrade option for SLR shooters who've outgrown their kit zooms, and are looking for better image quality and more creative flexibility. It offers a fine balance of zoom range and maximum aperture, while still being highly portable.
Pros: Useful combination of zoom range and relatively fast aperture, Very good image quality across most of the range, Compact size, Reasonably fast and near-silent autofocus, Effective image stabilisation
Cons: Somewhat weak image quality at wideangle (soft corners and chromatic aberration), Macro shooting a little impractical (very short working distance)
