did you try the 3D AF tracking thingy? ;p
erm ... there were no running cheetahs around, so how to try leh? i tried shooting the moving hands of the harpist, the auto focus is quite accurate imo as seen on the LCD.
this is the only picture i could bring out, approximately 3R size glossy print, ''reshot'' with my D80 on iso 1600 under flourescent light

was focusing on the harpist's right hand
