There is an explanation that you can see here:
http://dev.exiv2.org/issues/1328#change-6131
Basically, you should add the following in your .exiv2 file (or add it if
it already exists):
[canon]
197=Sigma 18-300mm f/3.5-6.3 DC Macro OS HS

It seems that some informations are from the right lens and other for the
wrong one.
Probably these informations ARE in the file.
Maybe Sigma is trying to fool the Canon body to get some optical
corrections from it?

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:
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 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
Mar
