At least a review with real world pictures.
A very nice test. It highlights the strange behavior for the 1:1 Nikon LV, which I rarely rely on, BTW.
The difference in SNR, especially for darker tones reflects what DxO put in a very cold but objective way: D800 is -way- better for low ISO vaues, which is good for my photographic habits.
I hope to see more tests like these in the future.
