This new lens from Sigma (18-250 zoom) comes in a Pentax mount. Pentax puts their DSLR image stabilization in the camera body and not in the lens like Nikon or Canon. Yet the description for all the lenses is the same - image stabilization in the lens. Is this a case of cut&paste product descriptions or would using this lens on a Pentax camera have double image stabilization (both lens & camera body)? [more inside]

I bought the Pentax K100D dSLR, partly on recommendations from here, and I love it. I have the 18-55 kit lens and the 50-200 zoom lens, which I mostly use. Now I would like to buy a faster in-between zoom, somewhere from 24-28 at the low end to 75-135 at the high end. I am trying to figure out whether to buy a Pentax, Tamron, or Sigma lens and am getting confused with all the contradictory reviews. The Tamron 24-135 is praised to the skies by some and trashed by others. I am leaning towards the Tamron 28-75 but would like something closer to 100 mm. Any advice?
