ExifTool by Phil Harvey
Buried somewhere in there just might be a GUI version for Apple. (ExifTool GUI for Windows devices is no longer officially supported and the mapping/geotagging support was broken by Google)
Thanks, PDL. I'd actually read about ExifTool, but I couldn't tell how new it was or if it'd work with Macs. But it's good to know it works, and I may just have to give it a try!

I looked in the LR Classic help files, and I think I read the metadata section you mention. But I'll re-read it because . . . well, it wouldn't be the first time I'd overlooked something!
But another thumbs up for exiftool is good to see!

Pentax Tags
This lists three (3) relevant EXIF tags that store the focal length. "0x001dFocalLength", "SRFocalLength" for Shake Reduction, and "LensFocalLength", an extra record that keeps all Lens information.
Note that the first tag requires a 32 bit integer and the other two only a 8 bit integer, usually meaning "35mm" is differently encoded.
It helps to create a DNG file with the correct expected values using the camera, than compare the three EXIF tags and copy the values over.
If this is not changed correctly in all 3 places, it's very likely that applications reading the EXIF tags will misbehave.
Do make copies of any DNG files, before changing.
Copies, yes. Sage advice, always.
Interesting to note there are three instances of FL to tend too. Thanks for pointing that out!

Thanks, baro-nite.
I used GraphicConverter years and years ago, and it's good to know it has ExifTool built in these days. I really should look into that app again. . . .

Lots of votes for ExifTool. Thanks, folks.
I also saw a lot of apps on the Apple App Store, but sometimes it's hard to tell what's good, not so good, and just not good at all.
Right now I simply made a keyword tag for the A 100/2.8 macro, but delving into the Exif would be a better solution.
I'll try to remember to post what I try and how it worked, which right now might be ExifTool and LensTagger. . . .
Thanks again,
