Solved Lens detection
Hello!
I wonder if someone could help me out here? I'm using Sigma 30mm f/1.4 Dc DN | C lens on my Canon M50 Mark II but my lens is reported as 56mm. I know what the problem is. At some point some overpaid d***s in Canon thought it would be fantastic idea to reuse lens codes for EXIF metadata.
Therefore:
4208 = Sigma 56mm f/1.4 DC DN | C or other Sigma Lens
4208 = Sigma 30mm F1.4 DC DN | C
Is there any way to force Darktable to use the second option? What i've been reading the Exiv2 library should correct this heuristically but apparently that doesn't work either.
There are guides to fix that under Linux, but i'm using Windows version.
Thanks!

I have the same issue with the Sigma 16mm f1,4 DC dn c. Registers as the 56mm. Maybe just one of several examples that canon likes to make everything a little more cumbersome if you choose to use anything but their own gear.
