I have the Canon 70-200 f/2.8L non-IS, I have not used any of the other versions of the Canon 70-200 (f/4, f/4 IS and f/2.8 IS) so I cannot say how they compare in the real world. But at the end of the day I can say that I've been very happy with my lens, I've used it to take some great shots. Sure its heavy, however that's something I can live with.
