Nikon D600 vs Canon 6D High ISO Candle Images - Michael Andrew Photography Blog

Here's are sample images for the D600 (and by extension the D800 I guess) vs the 6D high ISO. I have no idea where the DxO scores come from but this is pretty definitive. The D600's dynamic range at these higher ISO's is like... 6 colours. And unless there is something I don't know about Nikon's new crazy firmware or some noise reduction or dynamic range re-expansion mega-hyper doodad technology, I have no idea how they could possibly justify those numbers. There's also quite a lengthy YouTube video testing the rest of each camera's capabilities. I watched it once when it came out, be warned, it is really long but quite comprehensive.
