Verdict
The Tamron AF 17-50mm f/2.8 XR Di II LD Aspherical [IF] is a very serious performer and an obvious alternative if you can't get warm with the Sony standard zoom lenses. In terms of resolution it is easily able to match the Zeiss ZA 16-80mm f/3.5-4.5 DT for instance - that is technically. Unfortunately the lens suffers from strong field curvature at 17mm which may push the corner portions out-of-focus. The level of distortions is about average in this class whereas vignetting and lateral CAs could be somewhat better. Mechanically the lens isn't top notch but it compares very well to other lenses in this price class. All-in-all it's an attractive offer and surely worth a deeper look when shopping for a quality standard zoom lens that does not require a 2nd mortgage.
