How to force Lightroom to use a specific lens profile?

Question

I use a Canon 6D and a Rokinon (Samyang/Bower) 14mm f/2.8 for some fun UWA shots. I had already downloaded a lens profile using Adobe Lens Profile Downloader to correct for the mustache distortion. Even though it was for a 5D2, it showed up and automatically applied when I selected "Canon" from the "Make" drop down list in Lightroom's Lens Correction panel. It wasn't perfect, but generally did the job.This was all working fine until today, when it will no longer select that lens profile. It defaults to the Canon 15mm f/2.8 when I select "Canon" in the "Make" drop down, and if I select the "Profile" drop down, it doesn't even show up in the list available for selection.Can I force LR to use a specific profile? How does it decide what to populate in that "Profile" drop down list?Edit to clarify LR version 4 on Mac OS X 10.8.

Answer 1

Have you tried selecting "Rokinon" for make, and then "Rokinon 14mm f2.8" for model? I don't have that lens, but I do see those options in my copy of LR, and am able to select them both.

These profiles are lens-specific, so no need to choose "Canon."
