Electronic viewfinders, crude when they first came out, are now almost as good as optical and the time will come when they are better. Remember not so long ago when people said digital will never be as good as film? Times change.
Eventually we will have mirrorless cameras that exceed the limitations set by mechanical mirrors.... and that day is coming soon. We already have 4/3 cameras which exceed the 7D in IQ and getting close for focus. A mirrorless 7D2 would not supprise me..... and if it works better than a 7D, who cares if it has a mirror or not..... unless you really like mirror shake in your pictures...
Excellent points although I still think EVF technology is not there yet in one or two years? possibly but I dont think that likely. Maybe 5 years
The day will probably come where the EVF has its own dedicated processor to make it lag free and insantaneous
of course there are all the other benefits that can be put into an EVF like on screen information and overlays
who knows they could even have RED AF points! (one day)
Well maybe, just maybe, Canon has something up their sleeve which makes the EVF what you want, and now instead of in a couple of years. Not saying it is, but just maybe. Probably not though, I agree. I'm hoping it'll be something sensor related, like a completely new process and vastly improved tech which will migrate up and down the camera lines over the next few years.
