There are too big problems with the EVF on the Fuji. I also own the OM-D for comparison. The first is the rubber eye guard with does not block light coming in from the sides and is hard to use under certain conditions. The second problem is the eye sensor to the right of the EVF. When you have the display set to eye sensor and the sun is to your back and hits the sensor the view in EVF goes out and returns to the LCD. On my OM-D with the EP-11 rubber eyeguard any outside light is completely sealed off and the eye sensor is inside the boundaries of the rubber eyeguard so sun light never hits it.
