Technically the D800 has a higher score if you sum and average all the bars, but apparently that's not how DP review calculates the overall score...very strange...or maybe they weren't willing to deal with the amount of fanboy mail from angry canon people that are too inmature to accept these are just tools?
I guess giving both the same score is the most logical choice. Or maybe it would be best to take the score out from every camera since it is clearly fudged to tell people what they want to hear.
But regardless, this pretty much matches my own experience with the D800 having ACTUALLY USED one for several weeks now. I know, crazy idea, considering I can fully evaulate the D800 by reading to message boards and seeing 100% crops right
Both are very close but at the end of the day choice comes down to the personal needs and expectations of each photographer. In my case, a mere 2 fps and a few more ISO stops which are barrely up to my standard of usable just aren't enough to keep me with canon. Not to mention the soft video output and lack of 4:2:2 output of the 5DmkIII was a huge letdown.
I'll be looking forward the 5Dmk4 and D900 to address the remaining weak points of each camera. For now, I got 3 years of D800 images ahead of me.
life goes on
