Product description
Announced Sep 17, 2012

The 17-70mm F2.8-4 DC Macro HSM OS was the first lens released in the 'Contemporary' category of Sigma’s lineup. Designed to be an ideal all-purpose lens for APS-C sized sensors, the Sigma 17-70mm F2.8-4 covers an effective focal range of 25-105mm. This standard zoom is also equipped with a Hyper Sonic Motor (HSM) and an Optical Stabilizer (OS). The construction of the 17-70mm comprises 16 elements of 14 groups, including two FLD glass elements which Sigma says have performance equal to fluorite, with one SLD (super low dispersion) element to reduce color aberrations. The 17-70mm F2.8-4 Macro DC HSM OS is compatible with the Sigma USB dock, which allows some aspects of its feature set to be customized by the user.

Our review

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. Autofocus and image stabilisation both work well, but image quality at wideangle isn't the best.

Good for: Photographers looking for a high quality, general purpose zoom for everyday shooting.

Not so good for: Wideangle or close-up shots
