I would like to be able to add the lens (EXIF) setting as a keyword. Also, I believe I would need to remove the spaces (e.g. EF 16-35mm f/2.8 USM").

It would be something like exiftool -keywords+='$Lens', but I believe this inserts the literal "$Lens" as a keyword. Is there anyway to do this? My workaround is to use the "if" and test each lens then hardcode it into my script. Not optimal...
