Hi, my lens is not yet supported by lensfun. I therefore searched for a
method to to get the right distortion and chromatic aberration profile to
be used in daktable. (And I was not very successful applying the "manual"
method using Hugin.)

However, as this is a modern lens the profiles are already integrated in
the RAW file and I therefore followed this procedure:

   1. convert the RAW file (NEF) to DNG using Adobe DNG Converter
   2. extract OpCoodeList3 parameters from DNG file using dng-validate.exe
   (at the bottom)


I assume I can implement these values using the lensfun distortion profile
model "acm".
However I'm puzzled that values are provided in several "planes".
Are the planes referring to different color channels?
How to implement the planes in lensfun?
How can I cover chromatic aberration using these information?

Thanks in advance for the insight!

Sample output from dng-validate.exe -v:
