I certainly do and was about to bring it up.
This ongoing Tokina-Hoya-Pentax-etc. thing is getting a bit old to be dragged out again.
In regard to shift to MF, Tokina says that you push/pull the focus ring forward/backward to engage/disengage AF/MF. I'm sure I have that backwards someplace but you get the idea.
Not at all like Pentax "Just turn it until you like it" Quick Shift.
They may both use direct current but I don't see anything of importance there.
