How is Sigma? does this focusing behaviour sound familiar? or it locks on focus snappily?

It's pretty much point and shoot--no noticable hunting or indecision. However--

I’m pretty sure its the lens more than the camera

I'm way less sure about that. I got this lens after I had moved to the K-3, so I don't know directly about how it would perform on the K-30. But I can say I had several other lenses that were nearly unusable in the dark on the K-30 with focus-hunting, but that behaved entirely differently and more surely on the K-3. If the Tamron hunts all the time, then I'd be more convinced it's the lens. If it's only in low-light, it could very well be the camera.

I tested my Tamron 17-50mm f/2.8 further on my K-30 and a K-7. Yes, the AF is significantly slower in low light on both cameras but it is not quick enough in bright light either. It could be that both K-7 and K-30 have the same metering and AF functionality, so I'm back to square one LOL

I warned you about the inconsistent Tamron 17-50 AF a while ago...you did not believe me

You were right; my bad

I tried a 17-70mm f/4 SDM lens. The AF speed is definitely faster and decisive than my Tamron 17-50mm f/2.8. A choice between a lens (P 17-70) that probably won’t last more than a year without failing the SDM motor and a lens (T 17-50) that is lame for focusing by default. Such are the choice Pentax users have to live with
