Hi Lee,
I know about the lensfun library and I worked with the manual adjustments, but it is a little bit annoying and doesn't get me to a proper solution. I still have waves in straight lines, so maybe it is a problem in my workflow.
As I described before in Darktable it isn't a problem, the difference is, or my problem now is, Affinity Photo isn't free and it doesn't work, Darktable is opensource and it works.
I know, Affinity Photo is a great peace of software and you are working hard on it, but it isn't useful for me at the moment, if it doesn't work properly with my camera or it's lens...?!
So, what I meant, the profile for the G7X is nearly the same as the of the G7X Mark II, I wanted to know, if there is a way to create and copy the profile of the G7X to that of the G7X Mark II to work with until the profile is added to the lensfun-list.
