YMMV, but I've been unable to get reliable CDAF with any non-Pentax lens on my K-5.  Sigma offered to 'fix' my 70-200 so that it would work, but I haven't sent it in yet.

Would be worth a try to ask Tamron about the 70-200 then ...

Flawless with my Pentax lenses, however.  It's a little slow with the 18-250, but it gets there.  DA40 is VERY fast in CDAF on my K-5.  It can hunt with my FA100 macro but will eventually find very sharp focus.

Good to know! Thanks for the info.
