Perhaps that's what's in the EXIF data.
You'd need to look at the EXIF data itself in one of the photos with something like exiftool to see what it says.
If you don't have exiftool, as William Lloyd suggested, you can also look at the EXIF with Preview.
Open the original master image file in Preview and and open the "Tools" menu from the main menu bar. Select "Show Inspector" and open the "Exif" tab. For example:
What does the Lens Model and lens id show?
Thanks for the information, the knowledge was helpful, but the Lens Model in the "Exif" says the it is a "Sigma 17-50mm f/2.8 OS HSM". I don't have a Sigma, I have a Tameron Lens F/2.8 17-50. I looked in Aperture under "Exif" as well as Preview under Exif. They both say the same?????

Then that is how MacOS X interprets the EXIF tags.

If the wrong lens data are really bothering you, you might try to fix the exif with exiftool:
