For me it is mystery, why Pentax hasn't decided to introduce USM lenses? After all they have long-term experience in complicated ultrasonic medical devices and if Sigma can introduce their HSM lenses and bodies (they sell far worse than even Pentax SLRs) that can use it, then why Pentax couldn't do the same? That should even be easier to implement than IS - KAF2 bodies already accept signal from lens (FA* in this case) not to use in-camera AF motor (when AF/MF clutch on FA* lenses is in "manual focus" position) and most of them have power zoom contacts, that could provide power to ultrasonic motor in lens. This is really strange...
