How is the AX2000 auto focus?
 

How is the auto-focus on the AX2000? I keep waiting for a HD camera with AF at least as good as my VX-2100. I video tape figure skating so it is important for the camera to be able to follow the skater around the rink without grabbing busy backgrounds. The VX-2100 does an amazing job of staying locked on the subject.

I'm interested in comments from AX2000 users.

The auto focus on the NX5 is very good and since the AX2000 is pretty much the same camera with less features. I would think it would be just as good.
