Depending where I am, like shooting a game in the bright SUN, I can't even do that. There is sooo much glare on the back screen that it is useless, without something like a "Hoodman" device, or a jacket over the camera and me (like looking at view camera ground glass screen). The EVF is immune to that problem, which is one reason I LIKE using the EM1 in the sun.I like the old guy on the right, squinting at his LCD like he had never heard of "mirrorless."
I rarely use my LCD, because I'm in the half of my life when I pay for the perfect vision I had in the other half of my life. (Luckily, I have a spouse who spent half her life with glasses. Now, I call her my "splinter puller." )
If the EM1-mk3 can do half of what the EM1X can do, I will gladly switch from my D7200.
The EM1X can do what I want, but I can't afford it, so I have to wait for the mk3.
Kelly's comment is dead on target for me, the weight of the FX/DX gear is just too heavy, for this old man. The m4/3 gear lets me still shoot and be mobile, vs. fixed in a chair with a heavy lens on a monopod.
