Having done this:-
... how do you instruct the camera what (moving) object is to be kept in focus? Assuming quite a few options are in the field of view.
There are three parameters you can set to tell it how to track. There are six sets (use cases) you can adjust and select one case as the active one.
The three params are tracking sensitivity, accel/decel tracking, and AF pt auto switching.
I haven't played with them much but reviews/previews have covered it fairly well.
I did set tracking sensitivity to minus (lowest), AF pt auto switching to 2 (highest), focused on something, then moved the camera around, and it stayed with the initial target and switched AF points until the object was no longer covered by an AF point.
