Ever since I received my K5 a year or so ago, I've had occasional problems with the AF that span across several lenses.
It's like the camera picks a focal spot and then won't leave it. If I refocus the lens manually or point it at something closer or further, the camera doesn't respond. Sometimes hitting the AF button will wake it up and make it refocus where holding the shutter release halfway won't, but usually nothing will fix it except turning the camera off and on again.
I've noticed the behavior with my DA* lenses (16-50, 50-135, 60-250) and I'm 95% sure with my Tamron 28-75. I forget if I've seen it with the wide angle lenses - they tend to be in focus most of the time anyway.
Has anyone run across this before? Any idea why it's doing it or if there's something I can do to fix it without sending the camera in?
It doesn't happen terribly often, but it's really annoying when it does.
