DxO just released their sensor tests for the Nikon D600, and the new full-frame DSLR has posted a 94 overall score! It looks like the D600 has been cheating off the D800’s test! When DxO tested the Nikon D800, it scored a 95 while the D800E scored a 96.
In low light testing, the D600 rivals the D800/D800E with a DxO score of 2980 ISO. The difference between the cameras is imperceptible.
The Nikon D600 scored a dynamic range mark 14.2 EVs, which is only 0.2 shy of the D800. When put head-to-head against the previous generation $8,000 24MP full-frame D3X, the D600 stands out as the winner with 1/2-stop better dynamic range. At base ISO, the D600 (as well as the D800/D800E) surpass even the D4 at dynamic range. Only at high ISO does the D4 begin to pull ahead.
When compared with the current Canon full-frame, the D600 blasts past the 5D Mark III with a 2.5 stop advantage in dynamic range. DxO has not yet tested the new Canon EOS 6D, but it would seem to be a tall feat for Canon to make significant improvements over the 5D Mk III at the 6D’s $1400 lower price point. The Canon EOS 6D is not expected to be released until December.
