The lens name is not spelled out in letters inside the image file. It is represented by a numerical code residing in the MakerNotes part of the EXIF. There is a list of codes mapped to names at Phil Harvey's webpages (ExifTools): http://www.sno.phy.queensu.ca/~phil/exiftool/TagNames/Pentax.html#LensType
My hope was that Lightroom could be coaxed to map a code to a different name by providing a lens profile mapping the number to a Tokina name. I imagined you wouldn't have to rename the file or create a separate Tokina folder for it as long as it maps to the name you want for it. The problem of overlapping codes is not unique to Pentax/Tokina, btw. Here's one thread that indicates an issue with Canon/Tamron: http://www.canonrumors.com/forum/index.php?topic=649.15 It could be that your best solution is to use ExifTools directly. Some way down this page there is a recipe for changing lens names for Leica files. Should work for Pentax too, I think. http://www.l-camera-forum.com/leica-forum/digital-post-processing-forum/135236-changing-lens-info-exif.html Hope it can be of some help.
