In both tests, the cameras are set to a neutral picture style with the contrast all the way down. No lighting optimizer or high light tone priority turned on. In the first test I exposed for the dolls skin, I was the back and I am about two stops under. Both are set at ISO 1600.

Starting with the Sony I see the blue channel is noisy but not some much noise on the green. When we look at the Canon I would say it is about a tie on the blue channel noise.
