It is, isn't it? I don't use it as often as I should, but it's such an amazing lens. And so small.

Not really, no. The word you're looking for is "cheaper".
Optically they compare well, the build of the Pentax is better, it's smaller, MF is easier to use, it has WR, quick-shift. Images from the Tamron will not pale when compared to the Pentax, but the design of the lenses are very different.
