check out this real world comprisons between Canon and various lenses, this poster also tests a cheap vs expensive UV filter vs. no UV filter. All guessed wrong on which was which, ha ha.

He also compares the Canon and Sigma's 70-200 f2.8 and boy are the results interesting, especially when compared to the mighty Digma.
