Here's a few pictures I took a couple weeks ago with my 70-200mm f/2.8L IS II on my 7D.

200mm - 1/1000 @ f/2.8 ISO 125








200mm - 1/1000 @ f/2.8 ISO 160








200mm - 1/1000 @ f/2.8 ISO 200








70mm - 1/640 @ f/4 ISO 800








All of the pictures above except the last were cropped from the original down to only about 1/3rd to 1/4th of the original frame. I think this really shows how much detail you get from this lens! I took quite a few shots that day since I assumed many would be OOF, but nearly every one was perfect. I've been very impressed with the AF of this lens, particularly when tracking. It's probably the fastest and most accurate focusing lens I own. I had a hard time justifying the price of this lens before I got it, but after using it I have no regrets. Start saving your pennies - I'm sure you won't regret it either!
