Hope I'm right. >>>> Paul I sold my two K-20s to buy a K-5, in large part because those first responders cried how great/accurate/swift the AF was on the K-5. Now Paul, who I respect as a camera sensitive pro who makes money with his tool(s), tells me it's deficient? I don't think so myself, as it seems to get it right more often than not, almost every time if you auto-focus twice. It tries to track moving objects, doing better than my K-7. What no PENTAX does that I've owned is predictive follow focus. Memory is old and foggy, but I think my PZ-1p was better at that than any of their current DSLRs. I may be wrong on that, but it seems to smoothly follow a moving race car or running doggie, "predicting" where it will be when the shutter trips the next time (with shutter button down in fast multiple shots). The K series that I've had from *ist-D to K-5 seems to (covering my butt before any with better knowledge than I chime in) focus, stop focusing, focus, stop focusing, focus. In the K-5 the first, third, and fifth images will be the best. The others taken while the camera is still focused at the last photo. My K-7 would have the second photo in focus, and never catch up. Not that I can claim to always have a dogs eye, or even head, in the AF sweet spot all the time. If you try to use all 11 focus points under those circumstances, the camera will randomly decide the tree in the background is prettier than the dog running at you, past you, or away from you. I have more anal shots of dogs than head shots - they seem to know, and turn away. The PENTAX camera always sees the contrast of a dog's bung-hole as a likely fecal-focal target. I'll have to bring my clicker or dog-whistle to the park this afternoon.
