Trying to get Lens Info

[Leonard Smith]

Hi, I'm trying to use pen to get the lens info from my photos. I am having a heck of a time finding my way around the library. I can get the basic ifd0 data to load, but I cannot figure out how to get to the rest of the tags. I double checked the uploaded image to make sure it actually had the data stored, and it does. Any help would be appreciated. I've been banging away at this little project for a couple of days now with little luck.
