He must have really been moving or you used a really slow shutter. Pretty neat.
I take a bunch of airshow pictures (about 4 gig this weekend). In doing so panning with the planes as they move is required. I have tried it both with SR on and off. I do not see any improvement or issue no matter which way I do it. Doesn't the manual say to turn it off when panning? Anyone else have better luck with it on or off?
