Well, I don't know if it's Safox VIII or something else's fault but K10D focussing on moving objects really sucks. static objects — no problem, good, fast, accurate focussing.
Moving objects — another story. Try this: set K10D to continuous AF, continuous shooting mode, set some tele lens (50-135mm range) at fast aperture and take serie of pictures of a man, walking to you at quick pace. I bet that most (if not all) pictures will be back focussed. In AF-S mode K10D probably won't be able to lock and to take picture at all. Oh, and when you use AF-C + continuous shooting on moving object frame rate drops dramatically.
AF on moving objects is the area where Pentax lags far behind competition. While my daughter was small and was just crawling and walking, Pentax was wonderful cost-effective solution for my family pictures. Now she is running and the only focussing method I can rely on is to prefocus manually and to fire serie of shots when she is running through that spot. Of course it doesn't work with a flash

You'll see the truth about K10D AF-C...
Because of this hopeless AF on moving objects I stopped recommending Pentax for my friends and stopped buying Pentax equipment — started thinking about switching to Nikon. However still waiting for next month announcements...
