p.1 #4 · Alternative to Lenstagger Plugin+Lightroom
Lenstagger itself uses exiftools. I suggest spending half an hour with chatgpt to perfect an exiftools command that works for you. For example, you can ask
"what would be the exiftools command to add lens data to all my photos? I want to specify the lens name, max aperture, shot aperture and I want to apply to either a file or a directory."
You get the idea.

Exiftool. It's a commandline tool but the website also lists various GUI versions.
