Interesting read, a few of my observations...
I wish they would have thrown in a 7D or 70D while they were at it since they threw in the D800
The Nikon D800 is ... wow. I take back any previous comments I have ever made about huge megapixel DSLRs as unnecessary, because that is a lot of detail and nice results.
Same thing goes for the Nokia 1020, I thought that 41 megapixels was a total gimmick, but the results are pretty impressive, even though there is some detail loss due to "low dynamic range".
The iPhone camera did better than I thought it would, but full crops really show it's limitations. In the full image crops I kind of like the color of the iPhone versions better.
