Tamron are reverse engineered, or at least that has been said, so specs could be off a little.. I sent my K-30 to Tamron with my Tamron 70-200 because it was not lining up correctly, they adjusted it and it works perfect, as it also does with my K50 and a friend's K-50 too. I doubt they would do that for an older lens (unless you bought it new). Just make sure the contacts are very clean, you can use a little alcohol on that microfiber cloth that Steve suggested.
