NO Lens correction for Leica Q3 images

The Settings show Lens Correction is turned on. The Documentation says that the Leica Q3 (fixed lens) is supported.

But no lens correction takes place. The image retains high barrel distortion and vignetting that is REMOVED by the build-in corrections in the DNG file. These are evidently ignored by Topaz AI.

Steps to reproduce issue:

  1. Open a Leica Q3 DNG whether directly or from e.g. LightRoom
  2. Distortion is evident in preview and in saved DNG

This looks like a situation where they have raw support, but no lens correction support. Lensfun is the third party library they use for lens correction, and the list on the github suggests to me that the Q3 isn’t currently supported. A dev should confirm this though.

Would you mind sending in some more information to get a better understanding of the problem you are having with this particular type of image? Please send the following information:

  1. The original image file.
  2. The processed image.
  3. A screenshot or description of the settings panel so I can see what adjustments were turned on.
