DxO Labs performed their benchmark tests on the Nikon D800 and deemed it the best of all digital cameras. It earned an overall score of 95, which is 4 points better than all other cameras they have tested.
Perhaps to be expected, the D800 shines in landscape testing, boasting a 14.4 Ev dynamic range. The real surprise is its low light score of 2853 ISO — essentially the same score as the Nikon D4.
For portrait score, a measure of color depth, the D800 is tied for third place with a score of 25.3 bits, an amazing feat proving that it can stand among medium format rivals like the Phase One IQ 180 and P65 Plus.
