I don't think there is a problem with AF accuracy deteriorating with age. I've had my K5 since Feb 2011, use it every coupla days, and i'm not seeing any deterioration of the AF accuracy. I also have not noticed AF deterioration with my K10 or K20.
Try this, disable SR and put your K5 on a tripod using a 2 second timer. Put it on an f8 and see if it can take a sharp picture given all these advantages. I define sharpness to be sharp looking edges at 8x enlargement on the lcd screen. If you can't get there, then there is something wrong with the camera. If you can get a sharp edge at f8 but not at f2.8 then you may have front or back focusing.
Call up and tell Pentax servicing what you're seeing and get an estimate. I don't think you're talking a lot of money for this kind of clean and calibration action - but you'd have to ask them.
In any case, its good to hear that the NEX does that well wtih contrast focusing.
good luck, phil
