Oddly enough, the lense still produced some nice shots that I posted elsewhere on this forum.

A Promaster/Tamron connection was always my understanding though a Promaster/Pentax connection as well might not be out of the question. On the other hand, the Exif data might be a little suspect. I have a Sigma 50/2.8 Macro that codes in the Exif as a Pentax D FA 50/2.8 Macro. That would be a happy surprise if it were so, but alas the fairies did not transform my Sigma during the night.
Your Maine shots are pretty incredible, by the way. Looks like you made an excellent purchase!
