Now that DxO have released the testing numbers for the Canon 1Dx, I thought I'd have a look at how it stacks up against the D4 and 5D Mark III.
Vs the D4, the 1DX is -0.9 on colour depth, -1.3 on dynamic range and -179 on low-light ISO. The DxO score difference is "7".
Vs the 5D Mark III, the 1Dx is +0.2 on colour depth, -0.1 on dynamic range and +493 on low-light ISO. The DxO score difference is "1".
Does that seem right?
