Nice work. I just got this lens myself (moved from a Sony a700) and I am loving it. This is what I told a friend just after I got the lens (and a new 7D):
"I did a little shooting today. I was out front of our house trying to shoot a hummingbird at our feeder with the 400mm, and it wasn't focusing, then I said to myself, "focus limiter!", moved the switched, and then focused. The speed incredible, the focus was immediate and it was basically inaudible. I rattled off three shots before I knew what happened. I laughed out loud with joy. This is going to be fun."
