DxOMark just published their Canon EOS 5D Mark III test results and the Nikon D800 scored better in every category, including low light ISO capabilities. The D800 got the highest score ever given by DxOMark by even topping medium format cameras costing 10 times more.
With a DxOMark Score of 81 points, the Canon EOS 5D Mark III edges out the Canon 1Ds Mark III (80 points) by one point and gains two points on its predecessor, the Canon EOS 5D Mark II (79 points), putting it in 10th place overall (for all cameras) in the DxOMark rankings.
“Canon achieves its best Score with its new 22-megapixel sensor, although the difference is very slight with respect to the former number one sensor, the Canon 1Ds Mark III,” observed Frédéric Guichard, DxO Labs’ Scientific Director. “Even though Canon achieves the same performance as Nikon in terms of sensitivity, Canon is still behind its competitor in terms of dynamic range, Nikon apparently having taken advantage of the latest sensor enhancements that improve the handling of dark noise.”
Here are some more detailed comparisons between the D800 and the 5D MarkIII:
BTW, with the 5D Mark II Canon got thei highest DxOMark score ever:
