Can you try:
exiv2 -pt IMG_xxxx.cr2 | grep Lens
I got that on an other lens:
Exif.CanonCs.LensType Short 1 Canon EF
24-70mm f/4L IS USM
Exif.CanonCs.Lens Short 3 24.0 - 70.0 mm
Exif.Canon.LensModel Ascii 70 EF24-70mm

Maybe you can try also to update your exiftool-version (I've 10.67 here)

Hi
It seem to be exactly this model for my lens. But when I use
exiftool on a .CR2 file from my camera, it detect my lens as a
canon EF 75-300 too. (see file attached)
How can I find the right exit informations ?

Hi,
What is the exact model of your lens (from the exif)?
Is it: "Sigma DT 18-300mm f/3.5-6.3 DC Macro" ?
If yes, it is not in version_1 of lensfun database but it is in
version_2.
If you upgrade your database with the command "lensfun-update",
it will create the following in your home directory:
.local/share/lensfun/updates/version_1/
And then the lens will be in the file: slr-sigma.xml

Hello
I have a lens, the sigma 18-300 f3.5-6.3
The problem is, it is detect by darktable as a canon EF 75-300
I see the link for raw.pixls.us <http://raw.pixls.us> but it
seem to be only for camera, not for lens.
How I can tell to darktable that my lens is a sigma 18-300
and not a canon 75-300 ?
Thanks
Marc
