    Birds in Flight using 7D

    I find that using the point expansion works brilliantly for birds against blue sky, but is much less successful when the background is complex, e.g. trees, grass or the sea, when the AF tends to 'hunt' onto the background. That's using a 1D mk2 though, I've never used a 7D.
