One of the reasons I love my fast primes is they help my aging 70D focus in poor lighting.
Recently it occurred to wonder if this won't help mirrorless bodies at all: SLRs focus wide-open and close the aperture when you take the shot but think mirrorless preview at the set aperture so that you can see the DoF and features like Focus Peeking work. If I'm right then having a fast lens won't help unless you shoot wide-open (except for sharpness).
I know that the AF working range on mirrorless bodies tends to be a stop or two better than most SLRs but is that necessary to handle when you're focusing at 5.6 or smaller?
