Query: Great wide angle range.

I got this lens for my full-frame camera (5D), and it's a great lens to get into wide angle photography - sharp and versatile, plus it's very nicely priced for an L lens. Be aware that the crop factor of APS sensor cameras makes this lens more of a 27-64mm. If you have one of these cameras and you really want to have ultra wide-angle capability, you might be better off with something like Canon's EF-S 10-22mm.
