p.1 #1 · "Native ISO" of a7R II

With Canon the cleanest/least noise/"native" ISO starts at 160 with multiples of 160 (ISO 160, 320, 640, 1250, 2500, 5000, etc).

May I know if Sony's a7R II and other FE bodies have something similar as well?

Correct me if I am wrong it should be 100-200, 640-20366 & 32180?

I'm sorry, after looking at dolina's reply and the chart for A7rii, I don't see how those answers correspond. I have an A7, the curve looks linear throughout (except from 50-100), does that mean that I'll just get equivalent noise gain as I move up the iso range and I can avoid the whole (160, 320, etc) stepping from my Canon days?

edit- I looked at Canon 5d and 5dii, I think I'm right
