Xmp tag in raw file not writing into xmp sidecar

[tommyzebman]

I put several tags in my nef file including this:  "-XMP-aux:Lens<Composite:LensID".

  Looks good in output .txt file. 

---- XMP-aux ----
Lens                            : AF-S Zoom-Nikkor 24-70mm f/2.8G ED
---- XMP-dc ----
Creator                         : Thomas

Used this then to make xmp sidecar file:  exiftool -progress -ext NEF  -tagsfromfile @ -srcfile %d%f.XMP "DIR"    BUT, that lens tag does not appear.  All other tags are there I believe.

<rdf:Description rdf:about=''
  xmlns:aux='http://ns.adobe.com/exif/1.0/aux/'>
  <aux:FlashCompensation>0/1</aux:FlashCompensation>
  <aux:ImageNumber>4540</aux:ImageNumber>
  <aux:Lens>24-70mm f/2.8</aux:Lens>
</rdf:Description>

Seems like it should be near this area in xmp file.

Hi Tommy,

This is a FAQ 3 problem.  There is a Nikon:Lens tag that is hiding the XMP:Lens you are looking to copy.  Either limit the groups that are copied to the XMP, or copy that tag specifically.

exiftool -progress -ext NEF  -tagsfromfile @ -xmp:all -srcfile %d%f.XMP "DIR"

or

exiftool -progress -ext NEF  -tagsfromfile @ -all -xmp:lens -srcfile %d%f.XMP "DIR"

Do not understand it right now completely, but thank you it fixed it.

Run this command
exiftool -g1 -a -s -Lens FILE

The output should be something like
---- XMP-aux ----
Lens                            : AF-S Zoom-Nikkor 24-70mm f/2.8G ED
---- Nikon ----
Lens                            : 24-70mm f/2.8

The tag Lens appears in two different places and the wrong one was getting copied to the sidecar file.
