Lightroom/Camera Raw: Tokina 19-35mm F3.5-F4.5 (193) detected as Pentax-F 35-70mm F3.5-F4.5 on Pentax K1

Thanks, Boris.

Looks like this might be an older Pentax lens model, and Camera Raw/Lightroom does not have a dedicated lens profile for it. There is also no official Adobe profile for the Tokina 20-35mm so it's likely that you might have a 3rd party profile(s) that contains metadata that is causing the lens profile matching logic in the software to think the Pentax lens matches the Tokina profile.

Do you have a copy of a lens profile for the Pentax lens, and perhaps one for the Tokina 20-35 as well?

If so, I might be able to modify them to make the matching work.

I see what you mean now. Yes, the EXIF lens name is being overwritten in Lightroom and I understand why.

There is some internal code which looks up Pentax lens names via ID, and overwrites the EXIF lens name to accommodate a lens profile that might use that as the "Lens" metadata name in the profile. In the case of the Pentax 35-70 lens, the ID is "3 28" which is also used by 2 different Tokina lenses. Lightroom is giving priority to the native Pentax lens.

see: https://sno.phy.queensu.ca/~phil/exiftool/TagNames/Pentax.html for the lens IDs at "3 28."

It might be possible for us to fix this in a future release, so I will add a bug and see if I can find a reasonable solution.

Thanks for your patience.

Thanks for your help Chris.

In the meantime, I'll keep on LensTagger'ing.

Thanks,
