Chris, while you're having to go through this, there is a thread on Pentax Forums (I cannot recall it off the top of my head, but it can be found) that explains how you could change firmware of your DA* 16-50 to focus by the screwdriver. This change is fully undoable so that what you have to part with this lens, you can revert it to its original state.
