OK, looking at the comparison image on my work monitor (17") and I can see more noise difference as well as a better dynamic range on the K5. In case I have still misunderstood this, by dynamic range I am referring to the fact that I can see details of the back wall of the K5 shot whereas I have mostly shadow on the K7 shot.
