It's a beautiful lens at 2.0 which is what I bought it for; I love it for certain indoor and night sports. But... at f2.8, I like the 70-200/2.8 E FL better. I bought mine from a well know fashion photographer at a high price. I'm tempted to let it go to help upgrade my 400/2.8G to a 400E FL, but the price on these seems pretty low right now.
