I went to the lake today with the intent to do swallows in flight with the 200 f/2 + 1DMkIIN combo. Alas, saw no swallows worth pursuing. Instead, turned the camera to my stunt pijuns and gave the lens (and the camera even more so) a good workout.
The lens superlarge aperture as well as a speedy AF drive help camera's AF system quite a bit. These pijuns were photographed in full power flight, some 40-50 ml/hr ground speed, depending on wind direction.
Servo AF, Manual mode, 3 FPS, obviously handheld, IS turned off in order to eliminate its effect of fast focusing.
The aperture was: f/2.8, f/2.2 and f/3.2.
The first shot was the luckiest one.....almost point blank shooting. One needs to stop down a lot for that sort of proximity....which I didn't do, so the DoF was thin.
