Verdict

The Tamron AF 17-50mm f/2.8 SP XR Di II LD Aspherical [IF] VC is a very promising lens based on its specifications. However, it falls somewhat short of the high expectations especially when considering the excellent performance of its non-VC variant. The biggest weakness of the lens is the rather soft corner/border performance at large aperture settings. The quality increases when stopping down and it's certainly possible to achieve very high quality results. The level of distortions and vignetting is about average for a lens in this class. The good news is the unusually low degree of lateral CAs which increases the subjective quality perception at the image borders quite a bit. The quality of the bokeh is generally decent for a lens in this class.
The build quality of the lens is good although not professional grade (as can be expected in this price range). The AF is very fast whereas the short focus path isn't exactly suitable for precise manual focusing. The primary new feature - the VC (vibration compensation) - works very well and its effectiveness is easily comparable to Canon's native solution (IS). However, when considering all aspects here the Canon EF-S 17-55mm f/2.8 USM IS remains the lens to beat in this lens class.
