Huntersdad, I agree. But sometimes, with the awesome 8FpS I can also fire a burst of 3/4 shots at much slower SS and one of them might be just the moment when the bird is still. Very useful for low light IMO. Got a lot of pats on the back from my friends for this(1/250 secs, 5.6, ISO1600, 400mm, no IS), little do they know that its the camera!
