Oh, you're going to love it! Remember when you and I used mine to focus on those cows outside the restaurant where we had lunch with Zuzu when I visited? I'm assuming you got the f/4.5-5.6 version, as opposed to the 2.8 version? I'd love to have the 2.8 version, but the closest I'll ever come is renting one for the day, and even that's not cheap.
