Great Pics Bone, i always look foreward to seeing your latest pictures, I have been struggling getting good shots of birds in the air. Are you shooting off a tripod/ monopod? or are you free handing it? Is your lense the 70-200 L series with IS? looking at upgrading lenses and have started to rent lenses at Glazers to get a better feel for them before I buy. As always gret work.
