Pentax K-7 with Sigma 17-70

Hey there !

Does anyone out thr have a K-7 with the sigma 17-70 f/2.8-4.5?

If so, how do they work together, IQ wise, AF wise and genereal performace wise?

AF wise
It seems quite snappy to me, definitely faster then when I was using the Sigma 17-70 on my K10D

genereal performace (general performance) wise?
In my opinion, it's a great combo

I also have a sigma 17-70, and will use it on new K-x.

Isn't it too big for K-x?
