As can be seen in this thread, Pentax AF is now pretty good: AF-C Examples with KP (pic heavy thread) - PentaxForums.com

I used to own an SFX (SF-1) and still own an SFXn (SF-1n) Both had pretty good AF for the technology of the day. In fact there was no argument, at the time, that Pentax was ahead of the competition in this regard.

I'm curious as to the reasons you've changed your point of view from February. What has changed?
"One thing that may reassure you is that the Pentax autofocus system that frequently comes in for criticism is actually superb (indeed world class) in low light. On Saturday I shot a series of promo images for a singer and unfortunately she was running late and had to change for the shoot on location so we were shooting later than planned - much later!! As a result we arrived as the sun was getting very low in the horizon and I was really really worried that the shoot was in jeopardy. We shot 209 images from very late afternoon through sunset and into complete blackness. As the sun went down and into the night we resorted to using a lantern with a tea light to light her face. After the sun went down we shot for quite a while in complete blackness using a wireless strobe and softbox. It was so dark I couldn't see her facial expressions and could barely tell where her eyeball was to lock focus. I was getting seriously worried that I would accidentally leave gear at the location because it was in the middle of the countryside with no nearby street-lighting and it was cloudy so no moon either. The last 30-40 shots were taken in conditions of total black night. The K1 missed focus on 1 out of 209 shots and that might well have been my error in not focussing on the eyeball, but the tip of the nose. I have to say I was utterly astonished. I have never shot anybody in such conditions and I never expected the camera to be able to focus on her at all and yet it was painting her with its green LED autofocus assist light and locking on - truly extraordinary. It was so bloody dark I was resorting to the K1 LED body illumination in order to be able to even see the buttons on the back of the camera!!"

Pentax AF may not be great, but it's not that bad. Mostly, I only use the centre focus point.

And the crop:


These guys were moving at 50-55km/h diagonally towards me. That's around 14m/s. The AF unit did OK.
