Overall, there was really more useful improvements on this camera. Whether you are a new canon user or current fan and want to upgrade, this is it - you will not regret if you choose this unit. Hope this review helps a bit in your buying decision.
This camera works better in higher ISOs and you really notice the difference from the previous model; specially if you are a current user like me of the 5D MKII I notice an improved focus performance when im shooting in video Some improvements came from the Canon 1DX model I love the rate button...
There should be a swivel screen which is helpful if your shooting at lower angles
