Many of us would be thrilled to test the D7000 on cutting horse photos. Best I am able to shoot is horse and rider doing a timed jump around in an unlit barn Saturday after next. I will be using an AFS Nikkor 70-200 f/2.8 lens at ISO 6400 and center point.
Shooting thru dust seems to be the "greatest" test, as the AF seems to want to track those particles with a D3. Also cutting behind jumps can throw the AF off. Panning a 200 mph car is easier for me than a static subject without a tripod.
My limited testing has led me to believe the D7000 AF performance is way ahead of the 5D2. My action shot "keeper" rate is dismal with that camera.
