Lens Recognition for Yongnuo YN 35mm f/2

[tuxfanx]

Is your feature request related to a problem?

exiv2 doesn't recognize the lens Yongnuo YN 35mm f/2.
The lens is recognized by exiftool as Yongnuo YN 35mm f/2 and is included in the lensfun database under this name.

Describe the solution you would like

Would be wonderful, if you may add recognition of this lens to exiv2.

Describe alternatives you have considered

As a work-around I created an exiv2.ini

Desktop

• OS: Debian bookworm
• Exiv2 version and source: 0.27.6 and 1.00.0.9
• Any software using exiv2 and source: darktable 4.6.0

Additional context

I attached a jpeg picture taken with Canon EOS 5D Mark II. The lens is also available with a Nikon F mount

Seems to be present in the Canon tables already: https://github.com/Exiv2/exiv2/blob/v0.27.6/src/canonmn_int.cpp#L1900

As there are several lenses w/ this ID, it's possible that dealiasing for Canon is/was broken. Please search the issues, there are several similar reports about this.

For Nikon, a separate sample is needed.

Also, I don't see the problem on this sample w/ exiv2 0.28.1:

Exif.CanonCs.LensType                         198  Yongnuo YN 35mm f/2

Thanks for the info!
Unfortunately, I can't provide a picture for Nikon mount.
