I am finding that the distortion correction profile for this lens consistently undercorrects for rectilinear distortion throughout much or all of the lens's range. Anyone else experiencing this with this or any other lenses? I am not sure any distortion correction profile is perfect in all situations with any lens, and I can usually finish the job with a small amount of additional correction with the distortion slider, but it would be nice if the profile could get consistently closer to full correction.
