Ok, i don't have 5D mkIII, but i think a body design is one point, i heard AF of 1DX is way better than 5D3, higher ISO is better if beyond or higher 12800, some said the color rendition of 1DX is truer or better at highest ISO than 5D3, and ofcourse the fps is something not to close eyes about, sure there are things might 5D3 be winner, but at the end, what are you looking for? If you can't afford 1DX and want 5D3 to beat 1DX in all aspects then you did a crime for us, i should go with 5D3 instead then.
Is the AF difference largely because of the motors? I'd have though the detection/points is the same as the mk iii.
I'm not trying to justify my mkiii, I'm just open to the idea of picking a 1dx up, and I am about to pull the trigger on a 400mm f2.8, I am guessing it would team up better with a 1dx over a iii?
