Adobe Lightroom 2.1 Released
Previously Canon 50D RAW support was only due to a "release candidate" version of Lightroom. That is their version of a "beta" release. The full 2.1 release has official support for the 50D RAW format, and my quick tests seem to show that they've improved the noise reduction, but I've not really had a chance to compare apples to apples. You can get that upgrade here (you'll need to be a licenced owner, or you can download a trial). You can choose Win or Mac version in the "latest updates" column to the right.
Thanks for reading!
