First, a big thank you to those whoe responded and offered advice......
Originally posted by Adam I did run it through some tests, I forget exactly what I used, the chart shown in that article or a ruler, I can't remember exactly. I at one point had adjusted the AF to a +10 and I thought it seemed to help, but I don't think it did because I feel like I am getting very inconsistent results again.

Originally posted by macman24054 Have you tried blowing off the af sensor and cleaning the lens and body contacts. With what you are describing it sounds as if one or both of those things could be the problem.
I have cleaned the lens and body contacts but have not blown off the sensor. I will look into doing that. I assume I need one of those bulb air blowers to do that? I'll look up some info on a safe way to do that. thanks for the suggestion.

Originally posted by C_Jones You may want to check the K-3II to see if the AF area is set to "Spot" (center point) mode. If it is not, try it in that mode. When other AF area modes such as multiple points are used, sometimes the focus may not be made on the specific area you want it to. Using "Spot" mode is just a suggestion for checking to see if your camera still focuses on a specific point.
I have a K-3 II and I almost always use it in "Spot" mode.
If you need to use a blower for your sensor, below is an internet address of the Giottos Rocket air blower at B and H. It works well.
Giottos Rocket Blaster Dust-Removal Tool (Medium, Black) AA1910 It is on Spot metering. I've also tried using some of the other focus points with the same results, Inconsistency. Thanks for that link, I will check it out.

Originally posted by sungibr I would bet in dirt on af sub mirror and the af lens.
The simptons seems likely. I have had that before.
It could get easily dirt or get some moisture and you would never notice it until you get AF inconsistencies.
Take it to a trusty service center to check it, as they are sensible parts that could get easily damaged.
Wonder if any camera shop will clean it? Guess I could make some phone calls and see if any place around would service it for me.

Well that didn't take long. I found a camera service repair and retail store just about a half hour from me that actually has Pentax listed on it's website as a brand it works on!
