Hi Jostein, Thanks for the information. I only briefly looked into it so far. It might be usefl. However, I suspect that the lens profile, .lcp file actually only serves for the correction of the photos based on the lens, and to to assign the lens name into the EXIF. I suspect that the lens name is already in the EXIF inside the DGN/PEF file.
Indeed, what you suggested would've been useful if there were lens profiles for the particular lens(es), but there is none. (Actually, LR has no lens profiles for Tokina lenses at all, the directory with Tokina's name is absent.) Igor 2011/12/31 AlunFoto <alunfoto at gmail.com>: Btw, I believe this will only assign correct values automatically to images on import. To update data for files already in your catalog, I'm not sure what works. You could try to filter your database for the Tokina, select all images and try some of the commands on the "metadata" menu in the library module. If you use PEF and sidecar files, you could also do a massive search and replace with a command line tool (eg SED).
