Because I was bored, I just tried the following: Hold your camera in portrait orientation and look through the EVF with your right eye while keeping your left eye open. You see a double image. Now zoom the lens until the EFV view matches the unaided view in magnification. I used the 12-50 kit zoom for this. At this point you will see a somewhat exaggerated 3D view of the scene, due to the eye distance being made wider by the viewfinder offset (the DOF might also play into this). The EVF on the E-M5 seems to match at about 37mm while the VF2 finder matches at around 39 mm. This makes for a pretty interesting view actually. Too bad it's at an odd focal length. It would have been great if it had been matching at 45 mm... Rudy p.s. it's also quite interesting to see how much of a magnification error between the two eyes the brain can compensate for.
