Today, I tested the Dynamic-area AF - 51 points (3D Tracking) for the first time on my wife running towards me over a bridge. My camera settings:
* C - continuous - servo AF
*a1: AF-C Priority Selection to Release, the default selection.
*a3: Dynamic AF area 51 points (3D-tracking).

I pointed the focus point at my wife’s face and asked her to run towards me...total distance, max 10 meters away and closing in on me. Held the shutter button down and started taking pictures...the 3D tracking followed for the first 3 frames and then decided it wanted to focus on other areas instead of the initial focus area, my wife’s face. Of the 12 or so frames taken, 3 were sharp. Not a great result, so I asked her to take up her position and run towards me again. Same result as before, tracking starts of well but the "predictive focus tracking" becomes "non-predictive focus tracking" and more pictures are out of focus than in focus.

After some pleading, my wife agreed to run over the bridge and towards me once again. This time I changed the a3 Dynamic AF area to 21 points. Every shot was in focus.

So my questions to my fellow Nikonian D300 owners are:
- Under what conditions have you used 3D tracking and what results did you achieve?
- When should one use 3D tracking or 21 points?
- has anybody used 3D tracking to follow a "fast" moving object, like a wife running over a bridge ?

Your answer and comments are much appreciated.
Cheers,
Pedi
