I want to change the EXIF Lens information according to the recorded info. I always get the same error message. Can you help me? I'm running exiftool on a mac.

$ exiftool -v5 -lens="Lensbaby 2.0" -if '$lens eq "Unknown (65535)"' 2008_07_07_test_03535.dng

Writing Sigma:Lens if tag exists

Not enough values specified (4 required) for Nikon:Lens

Writing XMP-aux:Lens

Writing ExifIFD:Lens if tag exists

Not enough values specified (4 required) for Nikon:Lens

Condition: Use of uninitialized value in string eq - 2008_07_07_test_03535.dng

-------- 2008_07_07_test_03535.dng (failed condition)

    1 files failed condition

The tag "Lens" does not exist in your image.  Do you mean
LensType or LensID instead?  Also, to anticipate the next problem,
tags like LensType and LensID can't be set to arbitrary strings.
But if the -if condition passes in your command above,
the result would be to set the XMP:Lens tag, which is fine.

Thank you!

$ exiftool -lens="Lensbaby 2.0" -if '$LensID eq "Unknown (65535)"' *dng

solved my problem.
