Pentax K-7 AF-C vs Pentax K-5 AF-C

Found this video at the other Pentax Forums,
it looks like a significant AF speed & accuracy improvement.
Hopefully we'll see the photo samples soon.

I am wondering what lens that he's using. If that's our regular DA*16-50 / 50-135. That will be great. I guess our SDM is not that bad for speed & accuracy then.
