.. does the Sigma 17-50mm f/2.8 focuses faster than Tamron 17-50mm f/2.8? It would if Sigma is without screw-driven AF, is it?

I don't know the Tamron, so no opinion there at all. But the Sigma is an HSM focus--it's way faster/quieter than any of my screw-driven lenses. According to Sigma it's "a ring-type ultrasonic motor designed to provide quick and silent focusing." It does.

Pro: it's sure, fast, and quiet on my K-3. I useit as my walk-around evening lens since it's a bit faster than the 18-135mm. Also good for museums, churches, dimmer interiors.

Con: It's a bit big (77mm filter ring), but then modern lenses seem to be heading that direction...

Quibble: the zoom in-out twist is opposite that of the Pentax 18-135. Had to get used to that. <g>

Over all--no regrets about getting it at all. If I can get to it I'll post a couple of example shots later this evening.
