Rawtherapee doesn't recognise my lenses (canon ef)

Noticed RawTherapee never recognizes my lenses, and lists them as Unknown Lens (0) regardless of focal length etc

Darktable and DPP4 recognize it fine, and i can manually find it.
I often export photos to flickr, and there it appears as unknown lens which looks weird. Tried on windows and linux (EndeavourOS), both have the same issue.

I use an original (mk1) canon 5D with standard lenses (e.g. Canon EF 24-105mm f/3.5-5.6 IS , 17-40mm f/4L , 70-200 F2.8 IS etc), and these appear when i tried a Canon 5d MK4 on the same lenses.

Any suggestions?

Could you upload a sample affected RAW? I couldn’t reproduce the error with the raw from raw.pixls.us.

Cheers for having a look.

My own compiled RT 5.12 selects this lens via lensfun automatically
{EC3AED71-4EE2-4BA1-99E8-EF2FF992589E}

However, RT says
{49CE06C6-8C19-423A-83A4-614B7915480C}

According to ExifTools ist should be
{0086F9DF-0157-43FF-B3F5-6584F3CB51BF}

It’s a good idea to report this issue at GitHub · Where software is built.
