Originally posted by stevebrot Yep...it was all about display purpose. To be honest, I am surprised you did not run up against this problem before. LR has always limited auto display of lens name to those supported with the most recent installed update version. The only reason you are getting camera name is because it is in plain text as part of the base EXIF.

OK, here is an update to this old thread. I was never able to get Lightroom 5.7.1 to correctly identify the HD Pentax-D FA 28-105mm F3.5-5.6 ED DC WR (released in 2016). To refresh the discussion, I was importing jpegs usually, and just wanted the lens to be correctly identified in the metadata panel. I didn't want to do automatic lens corrections or process raw files. Most of my other Pentax lenses were correctly identified by LR 5.7.1, but not this "kit" zoom for the K-1 Mark II.
Today I finally subscribed to the Adobe "Photography" creative cloud offering, so just installed today Lightroom Classic and Photoshop. I'm now using the very latest version (11.1) of Lightroom Classic.
Unfortunately, Lightroom Classic is still not picking up the lens identity for the HD FA 28-105 lens. The lens field is just not shown in Metadata for that lens, while it is shown for others.
I checked the lens profile directories under Camera Raw, and I see a profile for the lens in question. However, the file dates on the profiles I see are old - is it possible that the new Lightroom Classic install didn't overwrite the lens profiles, and I need to do a "clean install" of Lightroom Classic?
I can't see why LR would not identify a lens that is already 6 years old.
Thanks - Richard.

Another update: When I open one of the K-1 Mark II jpegs using the HD 28-105 lens in Adobe Lightroom (the web version of the program, used to be Lightroom CC) the program DOES correctly identify the HD l28-105 lens in the metadata panel. I notice that when I installed both Lightroom Classic and Lightroom on my PC that the web version (Lightroom) has its own camera and lens profile directories as subdirectories in the program directory. So I looked in the Lightroom Classic program file folder, and I see under a "Resources" folder that Lightroom Classic also has both camera and lens profiles there, and they include the Pentax camera and lenses properly (with file dates of today).
I think the files I checked earlier under Camera Raw, which were in the Adobe folder under appdata and roaming, must have been from my old install of Lightroom 5.7.1.
I'll try importing some new jpegs tomorrow into Lightroom Classic - maybe it will pick up the lens correctly for new imports.
