This post is what I would call "a pointless exercise in futility"...
Easy Grumpy. Smile, it's EasterClearly, clearly, clearly, and well documented, the 1DX has the best sensor Canon offers. It doesn't have the highest resolution, but it has the best performing sensor.
I think what is confusing is that a casual observer could not pick out the best Canon on stats alone. I mean, if I were at the local electronics mega dealer and a 5D3 were sitting there boasting more mega pixels and a lower price and hyping its low lights capability and the only sacrifice was clicks per second ...... why would I spend double that? I mean I know from reading here and other places the image quality is outstanding on a 1DX. You can see that by what is posted. But on paper it seems like the 1DX loses to the 5D3 except for an extra processor to get the FPS up.
So you think a "casual observer" would assume the camera at 3499 is superior to the camera at 6799? Wow.
