Rick,
I am not sure. I can speculate that the difference could come from:
1) method of AF (isn't it different from LV and through viewfinder, - I
forgot how it is for K5/K3).
2) number of sensor points used in the two cases.
Also, Bill (or somebody else?) mentioned in this thread that some colors
can throw off the AF. I was not aware of that.

The strangest things about these AF experiments are:
1. Front-focusing on LiveView, which (I thought) sought to maximize the
contrast of the image on the sensor, and thus should be IN FOCUS
regardless of the lens in use; and
2. The 16-45 front-focusing with LiveView, and back-focusing with
viewfinder AF.
Thoughts?
