Pentax/Hoya would be very stupid if they let Tokina compete with them with a budget version of their own patent. And before anyone repeat the stupid claim that Pentax did not design this lens, here is the patent: esp@cenet — Original document
You can compare from Diminitrovs pages that it is indeed the DA*50-135/2.8 that is described in that patent: http://www.bdimitrov.de/kmp/lenses/zooms/_optics/50-135f2.8.gif

Why on Gods Green Earth would anyone now say that the DA 50-135 was designed by Tokina? Unless of course they are trying to blame the shitty SDM drive motor "design" on Tokina. (who does not use it)

This is definitely Pentax's baby... Their brilliant engineering. That is why they back it with an industry leading 1 year warranty!
