Charlie, I've been shooting an Olympus EM1 (with grip) since it was released . The size difference between the higher end mirrorless and my D750 is getting more and more negligible. I've purchased a Sony a7II (with grip), my hands are too big to shoot for extended periods with out the grip

.
The EVFs are getting better and better but I just cannot get the action shooting down with the EVF. What I really like is the fact that I can see all of the adjustments I make , in the EVF before I shoot. I am really interested in how my Nikon/Voigt/Leica lenses work, using MF, on the Sony and its' IBIS and EVF. I fully expect that the Sony FF cameras will keep getting larger.
That said, the EM1 w/o grip, with the 17 1.8/9-18mm mounted, is a small package for walk about. When Nikon responds with a FF mirrorless (which has to happen :)it will be interesting to see what size and shape.
Cheers,
Tom
Edit: the Leica is very interesting but totally out of my league
