New videos show off fast tracking speed of Canon 70D’s Dual Pixel CMOS autofocus system

Just last week, we shared an intriguing white paper from Canon on how the new Dual Pixel CMOS AF system in the Canon 70D is a massive improvement from other DSLRs for live view and movie focusing. Now a couple of video examples have popped up of the AF in action for movie mode, and the speed at which the system tracks focus is extremely impressive.
These videos come from the Japanese site Nikkei Trendy, and show the AF combined with face recognition, which is used to track a child as he runs across the scene. In the first brief video, the camera rapidly adjusts to track the kids face as he runs forward. It's not quite smooth enough for professional videography, but for home use it's much, much better than what DSLRs can do right now.
The second video is interesting because once the first child leaves the frame, the Canon 70D's Dual Pixel CMOS AF quickly locks onto a second kid, and focuses on them instead.
Keep in mind that Canon stated in that aforementioned white paper that it actually had to slow down the AF in video mode, because it was too fast, and was jarring. Which means when you're shooting stills in live view, it should be even faster to focus than this!
