Yes I tried it. Also confirmed that Pascal’s release is using exiv2 0.25, the old one.
Lensfun’s release is up to date (and in addition to that, lensfun is able to download the latest lens database, this works with ubuntu’s native version and also with Pascal’s). The problem is exiv2. The version that Pascal included in his PPA, and also the version that comes with Ubuntu, is really old and unable to identify new gear.
I guess it’s debian’s fault in the end (ubuntu just took their package). However it can be updated, as proven by the flatpak which uses 0.26 (and by debian expermental version).
