The item to note in DXO's testing is the 14.4 Ev's of dynamic range greater then the AD converters specifications. The file format and image processing does permit 16 bits and indicates what DXO is picking up is Nikon's software at work. In the end, they really can't provide a sensor performance test, but more of a system performance result. The initial result can not be technically above 14Ev, but after some processing, room remains in the file format and processing to make it happen.

In truth, all of these tests are subject to lens choice, software in camera, and system settings. I do not believe that any company computer display that can actually allow you to fully view the dynamic range and color depth afforded by either camera. Printers also tend to be a greater limit as their Dmax is somewhere closer to 10 stops worth and gamuts tend a bit narrow in comparison.

So while we can see the readouts from the files that explain the detail is there, we really can not print or see it on screen as that part of the workflow still has a bit of catching up to do. The situation is fine as I would always rather have a source that has greater depth then trying to extract from a lower quality to output a higher quality. The Nikon will be superior in well lit conditions with images intended for very large prints. The Canon will be able to match or surpass it in almost other conditions and will provide its user a bit more flexibility in more challenging lighting.

Now the limit of the quality of images is not often limited by the camera, but more in the photographers ability in the art and understanding of tools and technology.

Happy shooting!

it only scores that 14.5 at 8MP print equivalent normalized that is how they get above 14.

I'm curious why people aren't more intrigued by this review seeing as it doesn't exactly put the DxO test on it's ear, but it certainly shows that in RAW (with TIFF conversion) the results are rather different.

There's an interesting comment from them at the bottom of the page.

The version of the DXO software they have isn't able to read Canon raws from the 5d3 so they convert both to TIFF using the manufacturers' software and analyze that. It's definitely interesting that this is yielding a different result from dxo's own tests - although I'm not really sure what to make of it

That is utterly, utterly, wrong. If for no other reason than the simple fact that the 5D Mark II is in no way worse than the 5D Mark III in terms of DR.

nothing wrong about it, i have far less dynamic range in my MK2. i did a photo shoot with both bodies, the proof is in the pudding.

This is avery interesting test…it's a known fact that below ISO800, the D800 will trump over any camera in the market..everyoen knows that..that's why it makes such a good studio/landscape camera…above ISO800..i'll take the 5D3 any day.

However, what i'm more interested in this graph is not the DR on high ISO…it proves one thing that i've always believed in, the 5D3 (or any Canon camera for that matter), performs at it's best at ISO160! Just look at the results..ISO50 and 100 wasn't as good at 160…unlike Nikons that perform well at ISO50…
It's surprising how close the 5D3 is to the D4…

Iso 50 and 160 (and other iso's other than 100, 200, etc) are "derived" ISOs'. Your best results are obtained by shooting at "full" ISO's and using the principles of ETTR.
