Verdict

The Sigma AF 17-70mm f/2.8-4 DC HSM OS is a fairly obvious candidate for budget oriented consumers. It may not reach stellar performance levels but the resolution figures are generally very decent. However, for best results you may want to avoid the largest aperture settings due to somewhat soft borders and high vignetting.

Like most standard zoom lenses the Sigma shows a pronounced degree of barrel distortion at 17mm whereas other focal lengths are less affected. Lateral CAs are comparatively well corrected. All-in-all the performance characteristic is similar to its non-OS predecessor.

The biggest improvement over the older lens is naturally the highly efficient OS - Sigma's optical image stabilizer - which is just as efficient as Nikon's VR. The build quality of the lens is pretty impressive for a lens in this class and a nice contrast compared to the average plastic bomber here. The pricing of the Sigma lens is, as usual, highly competitive especially when taking the relatively large max. aperture in account.
