Have you updated the firmware? I know that AF performance was not mentioned as a fix in the newest release but it is possible there was just something buggy in your camera. Read my post that I just made a few minutes ago as I was experiencing awful results with the AF just as you were. I just now updated to version 1.10 and AF is seriously spot on. I am trying various lenses and focusing at various distances and have had almost no misses. I can't explain how or why this newest release fixed my issue but it certainly did some how.

At least give it a try. I was debating sending mine back but the past few minutes of experimentation after the update have been positive.

I am having the exact same issues and am at a loss. I have been using Pentax cameras for the past 7 years and have never had a problem until the k1. I only ever use AF.S with my focus point set in the center of the frame.

I purchase the Pentax 24-70 and 15-30 and they both either front focus or back focus pretty severely both with subjects closer up and further away. The problem is that it is so inconsistent that setting the fine tune adjustment does not resolve the problem. The lenses work fine on my k5 leading me to believe it is an issue with the camera. Granted these are tests done at 2.8 and I usually stop down a bit which give passable results but I am still at a loss as to what could be going on. I really want to love the K1 but until I figure out why the focusing is so erratic it is certainly tough to do so. Focus in Live View works perfectly nearly every time by the way.
