Pentax K-70 DSLR Review | Shutterbug

They are stating the Dynamic Range to be 11.5 F-Stops. They also state that the Nikon 5500 is 12. DXO puts the 5500 at 14, should we expect them to put the K-70 around 13.5?

I expected it to be higher than the K3 II but perhaps that is not the case. Though these tests aren't measuring with PS enabled which I would really like to see. Are there any PS DR tests for the K3 II?

I'm not sure why everyone excepts the K-70 to outperform the K-3 II- it's a lower model, after all! But they should be quite similar.

Maybe I am stepping on some toes here, but am I the only one who doesn't put a lot of stock in equipment reviews anymore, especially DXOMark?

Well, I think DXO is good for some things and not for others. Only a photographer can take a bad picture. That said, good ISO and DR performance certainly does not hurt.

It's DXO selling their own cameras with ratings higher than the competition. Much more difficult to trust for impartiality with their own skin in the game.

DXO Mark overstates dynamic range. The problem is that at least 2 EVs of the dynamic range they report aren't usable. There is no way that I ever got 14 EVs of dynamic range out of a K5 image -- things just got noisy and you just had to stop.

Well, the 14ev dynamic rang a was actually at iso80
