Also, the confusion between continuous autofocus and tracking autofocus doesn't help either.

Explain.

Well, Continuous Autofocus - you put the active focus sensors over the subject and the focus is continually updated as the subject moves. The camera focusses continually on whatever is under the active focus sensors. If you wander off the subject, then the focus gets lost, probably on the background.

Tracking Autofocus is very cool, but doesn't really work very well. In this mode you pick your subject with a focus sensor, and then as the subject moves around the frame, the camera is supposed to follow that subject and change from one focus sensor to the next.

This video is a good example of the effect.

As for the problem - well, it's often hard to tell which system people are talking about, so I'll need to wait until I see or do some actual tests.
