Hey everyone and thanks for all your answers!
Please forgive my bluntness, but I am wondering if maybe one or another of you need to lose that Pentaxian view (blessing everything that has "Pentax" written on it) and get a reality check. Please don't feel insulted, I am just trying to get a little sense into this discussion.
Ok, Pentax isn't first choice for sports. We've covered that. But sitting on stairs and alternately focussing on a grating and a barn doesn't qualify as sports - not in my book anyway. What I don't get is that some of you don't think something is seriously wrong when a modern DSLR with pro ambitions takes up to one whole second to focus on something - especially considering that an entry-level DSLR (which is ten years old) requires only about 1/5 of that time. I did not take a knife to a gunfight. I took a DSLR to a dancing tournament which isn't too hard on the AF - otherwise I don't see how the old EOS 300D could have dealt with it.
Edit: A camera that requires a whole second to focus is pretty useless for most things. Even children on a playground would be too challenging for it - and the thought of that is just plane pathetic.
BTW. What I should have asked more clearly is if your K-3's are just as slow as mine is. Would be really cool if someone tried out something like I did on the stairs.
If someone would like to meet with me so we could compare our cameras, that would be fine too.
To those who think that the camera has a fault...
Apart from sending it back, is there anything you can suggest how I could test this? A focus chart to me seems like the wrong tool because I am not having any back or front focus issues. My problem is one of speed. And this speed has nothing to do with the flash either. The test I did outside did not involve a flash - and I never took a shot, I just waited for the beep to signalize that focussing was done.
Kind regards (and still hoping for that decisive hint),

P.S. I like the way my K-3 feels and handles. I would really prefer to keep it!

Originally posted by Giklab @stevebrot read the paragraph above your quote. And come on, even the K-5 can do CAF for what the OP needs. The Sigma making tons of corrections makes me think the camera might be at fault.
@OP First try updating the firmware, maybe your camera just got derped a bit during production. Second, see if you have proper AF settings dialed in. If that doesn't work, either send in for warranty or replace tge camera.
Actually, I used the single shot mode for both the test and the dancing.
Concerning the firmware, I updated to the 1.02 before the tournament, as mentioned in my OP. What proper AF settings are you referring to? I had reduced the AF-field to nine before both test and dancing.
