I have the 70-200 f2.8 NON IS now and at 200mm, I get alot of camera shake due to the weight! It tried out the IS version and loved it! It arrives Tuesday from B&H! Shooting a concert September 9th at Mohegan Sun. I can't wait! I'm selling the 2.8 NON IS version and also keeping the 70-200 f4 (my first L) as a travel lens.
