A digital sensor/camera  with great DR means also exposure freedom.

This is inside a church and the light in the roof is the the high light, 5dmk3 and d800 are exposed identically time, f-stop  so there will be reproduction of the high light with out any clipping when the high light is adjusted the same in camera raw .

Then the rest of the picture are handle in the same way regarding middle tones and down in to shadows .The results in noise and details   is shown here.  100iso 1/80 sec F1,4  canon 35/1,4 and Sigma 35/1,4

I believed him what he said and the picture above. I compared these with my photoshop CS6, still same story as you got. Canon 5D MKIII still showing ugly shadow noise compare to Nikon D800 has no problem.  So its a serious side effect problem from Canon sensor though, as it is a flaw in the sensor noise ratio or so. Sony sensor has done very well to produce those to reduce shadow side effect noise problem. But they won't give away their Sony's secret. I had a goo dlook at iso info both are same 100. Bit disappointed to see Canon hasn't improved sensor yet I supposed but they still make excellent lens otherwise though. Although I heard that Canon videography is much better than Nikon for night shooting video with higher iso. It just blow away Nikon big time. Still photos seem to be different story though yes.
