As we all know, there are no lens profiles in Lightroom for Olympus and Panasonic m43 lenses, as distortion and vignetting data is written into the RAW file metadata and gets corrected automatically. However, does the same apply to other m43 lenses that have autofocus and talk to the camera, like the Sigma 19mm, 30mm, 60mm, and the Tamron 14-150? Are they corrected automatically? I ask because there IS a lens profile for my Sigma 60mm in Lightroom, and I've no idea whether I should apply it or not. It specifically applies to the m43 version, although there's another profile for the Sony mount variant. Also we've seen from sample pics that the new Sigma 30mm 1.4 has terrible barrel distortion when used with the Sony A6000, curious if will this be auto-corrected on m43..
