Lightroom & Samsung Lens question

[jstevewhite]

I have a K20D, Lightroom, and a Samsung D-Xenon 100mm f2.8 macro (identical to the D-FA 100mm f2.8 Pentax lens). It shows up in my Lightroom Metadata as "Unknown Lens". Anybody know how to get lightroom to recognize the lens? I thought it might be the camera that does that, but I think it's not. My Sigma 10-20 shows up as "Tamron (some zoom range) or various Sigma Models" and I doubt that Pentax put THAT in their firmware on-camera... Thoughts, anyone?

I use exiftool to tag most all of my lenses. I have an automator script (on OS X) for each lens; run the script, select the images taken with that lens, the images are processed, then tell Lightroom to read metadata from file. Perhaps tedious, but it works.
