One tip for AF, it needs contrast to get a focus, without any or little contrast it would have a hard time to get a focus lock.

If you've dark areas and the bright sun then it will try to make the best exposure. Also consider that the camera wants to get to 14% grey with all the tones.
A DSLR isn't a compact (point and shoot) camera.
As for the autofcus, it shouldn't matter if you use f/4, f/8 or f/16 the aperture stay wide open with any f-number when not making a photo so shouldn't effect AF, I can't say more about that.

Doesn't look like they have a K-mount version of that one.

It's here Stefan, last post in the thread. link
It's the same sensor as the K20D so I dont see any reason why it shouldn't be able to preform the same.
