The current RC2 prints different lenses if the the following two command are being used:

Correct lens:
exiv2 -pv E Canon_EOS_R_CRAW_ISO_10000_dual_pixel_off.CR3

This does only affect the new Canon RF lenses. LensModel is a new tag from CR3 files

I close this issue as I think the behavior is correct. However, there is work to be done on the identification of the lens type which is handled in PR "Test all Canon lenses #1428"
