Lens fun does update its lens correction db quite often but new releases are rare, hence new cameras take forever to be supported. Any chance to build Windows binaries against the devel version of lens fun to resolve this?
With the current Windows installer (next 6.0.0-beta3), We switch to current LensFun master development branch. Bundle is available here if you want to test : https://files.kde.org/digikam/ Gilles Caulier
Thanks I was already using beta3 but it does not seem to work like it should: According to http://wilson.bronger.org/lensfun_coverage.html the Canon Powershot G9 X should be supported but all I see is the older G9 (which was already supported in stable). (FWIW in On1 Photo Raw 2019, which supposedly uses lensfun too, G9X works perfectly)
As i know following a discussion with Lens-fun developer that you can find through the development mailing list archive from Sourceforge, it's clear that the library under Windows is provided as well and as never been tested in deep. Look last message from this thread : https://sourceforge.net/p/lensfun/mailman/message/36453434/ So, we support last code from from LensFun repository, but it's possible that library doesn't work as expected as under Linux.
