I'm pretty sure the likes of
Rob Galbraith (same link as above) would regard even the K-5 as a toy regarding sports AF.
Yes, you can still get great action shots with the K-5 but it simply isn't up there with the top performers. It doesn't need to be, AFAIC, but I'm not a pro earning money with sports shots.
Regarding the lack of lenses, I hear this a lot and always wonder why many people seem to work on the assumption that you can only use Pentax lenses on Pentax cameras. Sigma has a great range of long lenses and now that
Sigma started to produce weather-sealed lenses the last unique buying proposition Pentax lenses had seem to disappear.
What's wrong with using long Sigma lenses for sports?
P.S.: I trust Pentax engineers will be able to put an FF sensor into a K-5 or similar body in the not too distant future, but I don't see any chance for Pentax for getting into the sports market any time soon. Too much investment for no likely return and too much engineering. If they manage to solve the K-5's front-focus problem in low-light before the camera has been replaced by a new model, I might change my mind (a bit).
