I currently own a GX7 and this is my first post here. I love the GX7 and have it setup for back button autofocus. The button placement and ergonomics make this perfect for me — my thumb naturally rests right on top of the AF/AE Lock button. For those who own or have handed the GX8: is it conducive to using back button AF? Are the AF/AE Lock or Fn5 (in the center of the focus mode switch) buttons easily reachable with a normal grip? My concern is that the AF/AE Lock button is too far to the right of the body—requiring one to pull in your thumb awkwardly to use all the time—and the Fn5 button is too much of a stretch to use on every shot. Your experiences and thoughts are welcome.
