I guess people are demanding for the wrong settings I'd say...
Take a 2nd look on it as said here:

"Are you using default settings?? You need to optimize it to be exactly perfect. Dont use the face recognizer.. use the single point on the middle and change the sensitive and speed reaction on it. And then, with the touch screen you can also choose the point to focus."
In another note, another (usual) reviewer adds that:
"One note I've learned is that autofocus on a subject that is standing still actually works better when the DOF is shallower (wide open aperture) than when the depth of field is deeper, f 3.5 and higher, the camera seems to hunt or pulse more often on a subject that's just standing still. I mention this because off the top of the video you made a comment that shallow depth of field is the hardest for the camera to autofocus with, and I just wanted to throw my experience out there, that shallow depth of field *has helped* autofocus for me, on non moving subjects."
