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 remember reading about these spectacles that'd let you control their focal lengths by varying an oil film between two rectangles of glass that were held together by the frame ('oil inside the lens'). Links?

Photofilter: Which lens should I buy? I'm in the market for a new prime. I've narrowed it down (for various reasons) to either Canon 85/1.8 or the new Sigma 50/1.4. Do any fellow photogs out there have experience with either one or have a recommendation. Eventually, I want to go with the 85/1.2II but it'll be awhile before I have the cash. I'm looking for something with good bokeh as I like to shoot wide open and get short DOF. Currently, I'm using an old OM Zuiko 50/1.4 to achieve that but since it's not autofocus, I miss more in-focus shots than I like. In case you need to know to answer I shoot on a 30D and a 5D. Thanks!

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?
