I recently acquired the wide-angle conversion lens for the X100 and like it very much. I've been shooting RAW + JPEG so far, and when I import both images into Lightroom 4, it's clear that the JPEG has been corrected for distortion but the RAW has not. Do I need to set up a preset in LR to correct distortion on the RAW images? I guess I do, but I somehow had the impression that LR would auto-correct. Or maybe it corrects the regular (35 mm equivalent) images but not those using the wide-angle converter...? Thanks in advance.
