I am a right eye dominate but I choose to shoot with my left eye because I found it is excruciating to shoot with right eye and at the same time keep my left eye closed. When I am shooting with my left eye, the right eye can be blocked by the camera and I can keep two eyes open.
By the way, I think the EVF magnification in Xpro2 is too small and a little bluish. I think the Xt1's EVF is much better. I cannot tell the difference between the xpro2's 85 fps and Xt1's 56 fps.
