The ML team has done a great job with Canon cameras. I ran ML for three years on my 550d and recently upgraded to a 5d mk3 instead of a blackmagic cinema camera due to ML. However the mk3's sensor does not hold a candle to Sony's sensor in D800 or 7R. That sensor has a native DR of 14 stops without Dual ISO! It also has a lot less noise allowing much more underexposure than the mk3. If the above to cameras could do a RAW output they would blow the mk3 out of the water.
