All DA lenses have Quick-shift focusing (manual overide) IIRC the manual states it works in AF-S (Single) but not AF-C, my camera is usually set to AF-C for the majority of the time I use it.

I don't think any of the DA lenses that are shaft driven only have focus override. I've tried on many occasions to do so, and it won't move until you shift the camera body into manual, which retracts the drive shaft. The 17-70 seems to have focus over-ride, but if you move the collar very far at all with the release button half way, the motor forces the image back into focus, at least in center focus mode that I keep mine K20 in for imaging dogs.
