The Sigma 17-70mm F2.8-4 was designed to be the ideal all-purpose lens for APS-C DSLRs. With a versatile focal length and macro capability, the 17-70mm F2.8-4 is also equipped with a Hyper Sonic Motor (HSM) and an Optical Stabilizer (OS) for superior image quality. The HSM ensures quiet, accurate, and fast autofocusing while the OS compensates for camera shake when shooting handheld. The design of the 17-70mm includes state-of-the-art TSC material (Thermally Stable Composite), which allows for a durable construction as well a reduction in size by 30% compared to conventional models. Two FLD glass elements (with performance equal to fluorite) are incorporated along with one SLD element to reduce color aberration at the highest degree and obtain unmatched image quality. The 17-70mm F2.8-4 Macro DC HSM OS is compatible with the Sigma USB dock for an increased level of customization, including firmware updates as well as focus parameter adjustment changes. The perfect all-purpose travel lens, the 17-70mm F2.8 Macro DC HSM OS is a must have for any camera bag.
