Use this, GROUP AUTO FOCUS, continuous auto focus, center weighted metering. Shot at least 1/2500 sec. at one stop down from wide open.
And, personally do not like that lens for birds in flight. I use the Nikon 200-500 5.6 and get much better results at 500 mm. That lens is questionable at 600 mm.
Works fine for me...did you see my post, all at 600mm...
