Just musing.
If you have an OVF, you can pan across and see everything as you go.
If you have an EVF, you maybe experience "tearing". I have never noticed, but it's much reported.
Now try looking over one shoulder, and swing your head across to the other. Can you see clearly everything in between ? I certainly can't.
So maybe an EVF is somewhat better than my eyes in this respect, and an OVF much better.
OTOH, if I can get along with my eyes, I should be able to manage with either viewfinder technology?
