Pentax's screwdrive DA lenses with QSF are BETTER than everybody else's low-end lens-motor crap. They AF faster and allow full-time manual focusing. Sure, Pentax needs SDM in the high-end stuff, but sticking with screw-drive AF for the cheap stuff is a net win (and allows Pentax to do the small Limited lenses) Contrary to popular belief, lens motor AF is not necessarily better. With smaller lenses screwdrive AF typically outperforms lens-motor AF. With larger lenses the advantage of having a motor specifically designed to handle that lens's needs wins out and lens motor becomes an advantage. Note I say this as someone who currently shoots 1 system that's entirely lens-motor(Micro-4/3rds), 2 mixed systems (Nikon and Minolta) and Pentax. The fastest AF'ing camera I own is my Maxxum 7 with a screwdrive lens. Now Pentax could take a page from Minolta and start putting bigger motors in their cameras, a large part of the AF performance issue is simply anemic AF motors. -- M.
