    Canon EF16-35mm f/4L IS USM lens profile incorrect?

      Hi,

       

      it looks like Canon EF16-35mm f/4L IS USM lens profile distortion data is incorrect. At least it makes more damage to the picture than fixes. It's been like this since version 5.7 or 5.7.1, since this lens profile was included with LR.

      The lens model is correctly recognized by LR. In my setup (Win7 x86-64, LRCC, Canon 1D X, RAW files) I do not need to choose lens from the list -- LR does it automatically.

      This image is uncorrected, straight from camera (just exported as JPEG file):

      This one has profile correction ticked, distortion set to 100%, vignetting correction disabled. Look at the horizon line:

      Here are larger jpeg files:

      If you need more examples, I will be happy to provide.
