I am aware of the benefits of EVF. My concern is the response time of the EVF in very difficult situations such as panning around trying to lock onto a bird in flight.
And also how it deals with very wide dynamic ranges. The human eye has far more dynamic range than any display. It is only a matter of what portion the EVF decides is important, I guess.
It's a trade-off of evils, but for my $2K I would not jump over that fence, assuming life is better over there... without some serious assurances, and that is tough to do in a camera shop, for example. So like many new inventions it will have to stand the test of time. For me . And I think there are a lot of me's, which makes it a marketing issue, to some extent.
