5D3 native ISO test

One of the first things I wanted to know about this camera was how well it performs at high ISOs. 5Dmkii users will be familiar with the concept of "native ISOs;" and that multiples of 160 show the least amount of noise. Does this continue with the newest 5D? Recording with the lens cap on and boosting the noise in post revealed the answer: native ISOs apply to the 5D3, and the least noise is seen in multiples of 160.
