The one that holds a lot of water is their test on the D800 sensor. Yes, it dies blow the 5d3 sensor doors off and I've seen enough real world examples to support this. Do you have examples that contradict this?
I've personally owned both cameras and I concur: the D800's sensor is considerably superior to the 5D III. The DR is just in a whole other league. And the image quality in the underexposed areas is pretty astonishing as compared with the 5D III.
I think we all fully understand that DXO is only measuring a sensor and not the whole camera. Sensor aside, imo the 5D III "blows the doors off" the D800 and having owned both I can appreciate why whole-camera reviewers, like dpreview, give both cameras similar overall ratings.
Although I truly appreciated the D800 sensor quality, I sold mine and got the 5D III, knowing full-well that the 5D III represented a step back in raw conversion latitude as compared with the D800. But, I did it in order to be a lot happier in other key respects (like a truly wonderful Live View system and access to the best available wide-angle tilt-shifts). I wish I could shoot and enjoy the benefits of both systems, and the D600's lower price has me thinking about it. I probably won't return to Nikon though, as I have too many lens acquisition dreams to be able to afford/support two systems.
Anyway, as an owner/user of both D800 and 5D III, I thought I'd weigh in to say that, testing methodolgy credibility aside, I agree with DXO's overall conclusions that the D800's sensor is considerably superior to the 5D III's. And that suggests that I would likely have a similar experience with the D600s sensor.
