(in Japanese)

Test Conditions:-
Manual white balance, Natural custom image, NR Off, FA77 Limited lens used at f/5.6, LV AF, Direct JPEG.

Below is a snapshot of the ISO 3200 comparison pair:-

It is obvious that the colour response of the K-5 is more favourable. The colours produced by the K-5IIs is dull and less pure. As for the details and sharpness, I even found that the above K-5 picture is better! The noise of both cameras are very close and comparable, nonetheless.
