Optically the lens is great, the autofocus motor (SDM) system is slow and unreliable. What makes it worse, is when the SDM fails the manual focus also fails, making lens useless. Pentax should have taken care of this 8 to10 years ago. The upgrade is way overdue.

Thats odd!, I bought mine in a pawn shop, the SDM was dead, but manual focus worked. I converted it to screw drive and am very very happy with the lens.
