The question is, why is the 5D III so superior to the 6D in this area? Is it processing power or something else?
The 5D3 sensor is precisely 3 x the horizontal resolution of 1080p video, so all they have to do is combine each nine pixels into 1.
Right, but are they actually doing that? Everyone keeps pointing out how easy and practical it is to do but I've never heard or seen anything else supporting the fact they are doing that. I want to believe it, I really really hope they are but I still don't have proof.
