We’ve had tons of comments on our knowledgebase article that documents lenses supported by the Lightroom 3 automatic lens correction feature. Many of you see a lens in the list but cannot find the lens in the Lens Corrections panel in the Develop module.
The reason is that there are different profiles for raw vs. JPEG images. For a complete explanation, see the updated doc, Lens profile support | Lightroom 3, Photoshop CS5, Camera Raw 6 (cpsid_84666). (You may notice that we’ve also added Photoshop and Camera Raw support to the document as well.)
If your favorite lens isn’t supported, keep in mind that we will add support for additional lenses over time. To request support for a specific lens, please use the form at www.adobe.com/go/wish.
For Help using lens corrections, see Correct image perspective and lens flaws automatically in Lightroom Community Help. The topic has links to several good community tutorials, too. And for troubleshooting problems with the feature, visit the Lightroom user forum.
