K-r RAW Sensor Test From DxO

Here's DxO's RAW sensor test results for the K-r versus the K-x and K-7. They haven't done the K-5 yet. High ISO results for the K-r surprised me a bit. I was expecting identical results compared with the K-x.

I must be blind. I can't find them. Could you point us to them?

Edit: OK, I found a reference to this buried in another thread. I think this deserves its own thread.

The results on DXO show them to be practically identical. The slight deviation you see is an example of sample-to-sample variance.

Compare it to the Nikon D90 and D5000, Its the same Sony sensor.
I love the newest Sony sensor, Its high ISO capabilities with better glass gives you an awesome image. K-x with DA*50-135 2.8 is the best!

I was looking at the graphs, not just the front page ratings.
The SNR graph (the key measure of High-ISO capability) shows virtually NO difference between the K-R and K-X.

That also matches what my eyes can see - I can't see any difference between K-X and K-R High-ISO photos.

The DR graph differ a little to much to blame sample variation though, IMO.
