For Canon APSC-C cameras, the Tamron 17-50 f2.8 is a very good performance/price lens that you can get in the market if you don't have the fund for Canon EFS 17-55 IS f2.8 (the best walkaround lens you can get (IMO) for Canon APSC-C camera). Other than having a big aperture, it's solidly built, medium weight, focusing speed is okay, focus is quite sharp, and price is very affordable (~ 1/3 to 1/2 price of Canon EFS 17-55 IS f2.8).

If you can add a bit more fund, you can get the VC (vibration control) version for the Tamron 17-50 f2.8. VC/IS is useful when you are shooting in low light condition for stable object.

The only short side is, if you like the vivid colour saturation of Canon brand lens, you may not get that from Tamron lens. It all depends, different people have different favours - some people look for colour accurancy, some people don't. Canon lens are always sharper in colour than other brands.
