Hi John Nall,
You need to install the lens profiles in order to see them in Lightroom.
Please refer to the below link to download them to the following location on Mac or Windows respectively.
Profile File location in Mac OS X:
- /Users/[your user name]/Library/Application Support/Adobe/CameraRaw/LensProfiles/
Note: The user Library file is hidden by default on Mac OS X 10.7 and later. For temporary access to the user Library file, press Option and choose Go > Library in the Finder.Profile File location in Windows 7 and 8:
- C:\Users\[your user name]\AppData\Roaming\Adobe\CameraRaw\LensProfiles\
The lens profile at the link provided covers a single aperture so it's only useful for correcting distortion. I suggest installing the Adobe Lens Profile Downloader:
The below raw lens profile can be installed automatically and it covers the full aperture range (i.e. Profile Set) for correct vignetting correction.
I downloaded the profile downloader and used it to download the Samyang profile. I shut down Lightroom and restarted it. The image still cannot be adjusted. Is there a step I'm missing ?
The profile needs to be for your lens, be in the right place on your hard-drive, under the Users folders, and you need to be adjusting either a raw or a jpg depending on what format type of profile you downloaded. If the profile file is in the wrong place or if the lens or file-format type doesn’t match then it won’t be found.
I'll try to locate where the downloader placed the profile and then move it to...the users folders (sub-folder?). I downloaded both JPG and RAW for the Samyang, which I understand is the same lens as the Rokinon.

The Adobe Lens Profile Downloader will automatically place the lens profile in the user folder location. On my Windows 7 system it installs the lens profiles here:
On a Mac system they should be installed here:
Macintosh HD / Users / [your username] / Library / Application Support / Adobe / CameraRaw / LensProfiles /
In the Lens Profile panel select 'Make' > 'Canon' and then search through the 'Model' list for the 'Samyang 14mm F2.8' entry. You may have to scroll down through the list using the little arrow at the bottom of the list to see it.
I see two profiles in the lens profile folder--and only two. They were downloaded today. I had to burrow a little further than you described: lens profile/1.0/downloaded. the files are impossibly labeled 503e76c7cbdb49e2a6cee9d51164fadb.lcp and f5c90b35193145599a4e51fd3cf4ba59.lcp. I don't follow your instruction about scrolling down a list. Your list looks like one from the Adobe downloader. Sorry if I'm being a bit obtuse.
I just realized that the 14mm lens correction WAS working on pictures a few days ago. I haven't upgraded yet to the most recent version of LR CC so can't imagine the cause of it not working now.
Ok. I am obtuse. The panel you referred to is in the Develop section of LR. I found Samyang and now it works! Thanks so much for your assistance and patience.
The downloaded lens profile names aren't helpful, but you can open them in Windows Notepad or Mac TextEdit to see the lens name and the profile data. That's how I discovered the lens profile at DarwinsDen was lacking data for all aperture settings, which is needed to correct Vignetting.
FYI any Canon or Nikon lens profile listed in the Adobe Lens Profile Downloader (ALPD) will work with your Canon camera. It just needs to be the same Crop Factor as your camera or 1:1 (full-frame), which will work with all camera bodies (1:1, 1:5, and 1:6). When you select a lens profile in ALPD under 'INFORMATION' in the right panel click on 'Profile Set.' You want to use lens profiles that list the apertures you commonly use, such as 2.8, 4, 5.6, 8, 11. The proper vignetting correction will only be applied at those aperture settings. The Rating (1-5) shown is based on how many apertures are provided so I would look for '5' rated lens profiles. Just remember that a Nikon lens profile will only show up in the Develop module Lens Profile list when selecting 'Make' Nikon and with the appropriate raw or JPEG file type selected. You can then set it as the new 'Default Setting' for that lens.
