Verdict

The Canon EF-S 17-55mm f/2.8 USM IS is not a perfect lens but it lives quite well up to the very high expectations of the user base. The resolution figures are among the very best for an APS-C standard zoom lens. The center resolution is generally excellent even on the EOS 50D and the borders can keep a very good quality level. The distortion characteristic is quite typical for a zoom lens in this range (relatively pronounced barrel distortion @ 17mm, moderate pincushion distortion @ 55mm) whereas lateral CAs are unusually moderate. Unfortunately vignetting can be an issue at f/2.8 and the quality of the bokeh (rendering of the out-of-focus blur) lacks greatness in critical situations. The build quality of the lens is pretty good but in relation to its price tag Canon should have used a little less plastic - finally even the much cheaper EF 70-200mm f/4 USM L features a magnesium-alloy shell. All-in-all the EF-S 17-55mm f/2.8 USM IS is clearly a level up from the other Canon standard zoom lenses albeit a pricey one.
