If I were to switch to a PENTAX prime lens (non SDM i guess) would the autofocus be alot faster? If so, what's the best f1.4 (natural view) lens to get?

Yes, please don't judge your Pentax based on the DA*16-50. I have not had a problem with a single lens for Pentax except for that lens. I have returned two already due to defects. Others here have had similar problems ranging from AF issues, to decentering, doubling at the edges, etc. There is probably about a 50% chance you got a bad one. Heck if you use my statistically insignificant experience, there is a 100% chance you have a bad one.

Regarding a good prime lens, I shoot a lot of basketball games with the 50/1.4. No flash. Obviously LOTS of movement. Regarding SDM, I could take it or leave it. It is quiet. Big deal. It is not any faster though. The screw drive is not noisy in my opinion, just because you can hear it when your head is against the camera.
