The formats NEF, ARW, RW2 & ORF are missing the lens information, because it's not written to standard EXIF fields and must be constructed from MakerNote data.
These documentations describe how to do so:

- https://exiftool.org/TagNames/Sony.html
- https://exiftool.org/TagNames/Panasonic.html
- https://exiftool.org/TagNames/Olympus.html
This document provides an overview:

metadata-extractor has logic to identify the kind of MakerNote that is present:
