Stig and Dario,

I'm unclear why the focus point is different between the pictures,

Since I started dialing in autofocus for all my cameras and lenses, I've noticed that no two cameras are alike. One or the other of yours -- or more likely both -- aren't center focusing. Given manufacturing tolerances, I doubt that any camera can focus with complete accuracy without fine adjustment.

but I do notice the purple fringe difference.
Side by side at 100% in Lightroom 3.2, the K-5 image is sharper.
I don't know If I did something or it's the camera.
Here is another side by side comparison at iso 100.

The focus point is different in these two pictures so I am not sure different levels of purple fringing is related to the camera.

.. and I see much thinner purple fringing in the K-5 picture. This could be
another newly-discovered plus.
