I think the big news is that Pentax is in the tracking ball game, no matter what the results at this point, they are working on it. And for it first to appear on an entry level or mid level camera shows their committment to it.
As to your interesting question, how does any camera track an object moving through the frame. I would think it would be by a unique pattern of pixels at the focus point. So if one's camera focused on the arm of a person, the camera would continue to track that pattern until it disappeared or changed - at which point the camera will freeze
. And this tracking might occur while the camera is snapping off 7 fps. Boggles my mind. I suppose that Pentax had to really upgrade the processing power in the K30.
