The Pentax K5's RAW data is doctored, and even though DXOmark's graphs show that, they fail to mention it or take it into account in their "scores".



Look at the 18% SNR graph. The 5D mk II graph shows a textbook example of what a normal graph would look like, a smooth curve.

With the D3s we see a jump/angle at 12800, which shows us that there an EXTRA NR level is being applied. We can't tell what happened before 12800.

The Pentax shows an angle at ISO 1600.



With dynamic range it gets even more weird. The Canon 5D mk II shows a normal curve, the Nikon D3s a normal curve, but with its usual angle indicating extra NR. The Pentax K5 however shows a straight line. In short... doctored RAW data, fooling the "measurements" done by DXOmark.
