I was working on a professional review of the Sigma EX 50-150mm f/2.8 HSM for the lens contest, but Sigma has just discontinued the lens (presumably to be replaced by an OS version), so a review of it seems kind of pointless now. And besides, it would no longer meet the criteria for the contest.
I have a lot of pictures of the lens I was going to use for the review, so I figured that I would go ahead and share a few of them so everybody can see how this bad boy looks mounted on the mighty K-x! I also have quite a few sample pictures that I was going to include in the review, so I may post some of those later.
Here's some of the product shots:
