Verdict

Sigma has positioned the AF 17-70mm f/2.8-4.5 DC macro in one of the sweet spots of the market. It is priced beyond the (usually pretty crappy) kit zooms yet it still remains within the reach of budget shoppers. Even better than that it delivers a performance which matches and sometimes even exceeds more expensive lenses. This includes the in-house competition (AF 18-50mm f/2.8 EX) as well as genuine brand lenses (such as the Canon EF-S 17-85mm f/4-5.6 USM IS). All in all the lens has only one really weak spot - 17mm at wide-open aperture where the extreme border performance is soft and vignetting is quite pronounced (but still not worse than the direct competition). At medium aperture settings the delivered quality is very impressive. Combine that with the quite decent build quality and fast AF and it doesn't need a genius to foresee that this lens will be a quite hot seller.
