So.... Conrad, do you have a 100-400? I don\'t see one in your profile.... so before you comment on the speed of AF on a particular lens, you might want to shoot with one. I shot this image with a 100-400... this particular P-51 Mustang flies about 200 mph, which I think qualifies for \"quickly moving\", and it doesn\'t appear to be OOF.
