An added benefit of a good EVF is that it allows the photographer to view the scene exactly as it is going to be captured... or does it?
Here is an example from a recent outing with my Sony a7R and Zuiko 18mm f3.5 lens:

The Sony EVF works acceptably well in most situations, as long as there are no bright areas in the scene, but for shooting in winter it is easily bested by even the cheapest DSLR camera's optical viewfinder. I think manufacturers like Sony still have a ways to go before their mirrorless cameras will be ready to challenge traditional SLR cameras for serious outdoor photography.
