I would just like to say that Adobe's profile for this lens is crap when it comes to correcting rectalinear distortion and vignetting. It way overcorrects for vignetting and either over or undercorrects for distortion quite significantly at many focal lengths, depending upon the focal length. No profile for zoom lenses is perfect, I would guess, but this one is markedly inferior imo.
I have heard that DxO (and Perhaps Capture One as well) has a much better profile for this lens, but using that is impractical for me for high-volume work, for which Lightroom seems to excel.
Adobe, please fix.
