Originally posted by manishved this is a very well known issue with the Pentax system overall. Slow AF even in the flagship body (compared to Canikon or Sony). We will grow up, someday.
I would have agreed with you until I got the DFA 150-450 and the PLM. Both are much faster to focus than my other Pentax lenses, and the capability of the K3 seemed to increase with these on the camera. I'd like to try them with a K1 or KP to see how much it improves. Or better still, the yet to be released successor to the K3.
Since I have been using the DFA 150-450 I feel much more like the limitation is my technique with using the camera and lens than the lens itself (or the camera). To a degree I think the K3 was held back by the DA*300, and the newer lenses let me experience the camera's ability more.

I've owned all the DA* lenses, and it is optically the best of the bunch. I've had more luck than you with its focus, but the whole series would be better off rubbed out and started again with real focus motors.
Thanks for your feedback about the DA* lenses, Sandy! Certainly with the DA*300 I think it's optically wonderful but replacing the motor and adding a focus limiter would make it much more useful. It sounds like the SDM motors are still problematic.
