Funny how these threads emerge on this forum with each new Nikon review on DxO. As an interesting comparison Tech Radar, who is apparantly using the same DxO Analyzer software, recently posted a comparison of SNR and Dynamic Range for the 1DX, 5DIII, 1D4, D4 and D800. http://www.techradar.com/reviews/cameras-and-camcorders/cameras/digital-slrs-hybrids/canon-1dx-1091200/review/page:5#articleContentReally?
While it does show an advantage for the Nikons on base ISO Dynamic Range, the Canons actually shows a better ability to retain it over the ISO range.
actually what techradar results show is that they dont have a clue what they're doing. Just look at the progression of these lines, they dont even make sense!
According to the page you linked we can assume that:
Raw (after conversion to TIFF) dynamic range:
- D4 has the same DR either @ 100 or 1600
- 1Dx has peak DR @ 3200 and at 6400 it falls to the same level as @ 100 (magic!)
- 1DIV has a variation of .5stop through the entire range of isos
JPEG dynamic range:
- 1Dx peak DR @ 12800
- 1D4 solid DR from 100 through 4000
Its not the 1st time either that there is a discussion about techradar's silly results, just search around here or any other forum.
