I don't think lack of resolution is an issue with modern EVFs anymore. Plus, they can do things that no optical viewfinder ever could, like focus peaking, a live histogram, show the effect of the chosen white balance, simulate under- or over-exposure, maybe even motion blur based on the chosen shutter speed.
But then, as mentioned earlier, there are also things where they still simply can not match an OVF, mostly when it comes to contrast ratio, or colour accuracy.

I agree on contrast ratio in very bright sunlight, but as soon as there's low light, you have to balance in that EVFs can show more detail (with some noise, of course) than OVF.

And colour accuracy? How? Sorry, when I set white balance to incorrect values (and am not shooting RAW, but JPG) I'm in trouble as long as I don't re-check the first pictures. Sometimes I see it in the EVF, but daylight or flashlight setting are rather similar. I never see my mistake in the OVF.

My colour accuracy of the final pic I get (if I have to) with a gray-card and later in the RAW-developer - and this is unchanged since my first days of DSLR. I don't think that anyone gets colour accuracy by looking through an OVF - or you meant something else? I'm talking about the final picture.

Respect for each other's choice as well, I'd add. Sadly, not a trait of some "latest-and-greatest" fans...

I'm so glad, it's then a trait of some "earliest-and-smallest"-fans (or what would be the opposite of "latest-and-greatest"? It's good to have a drawer for each opinion, that makes discussions so much easier, right?). How about your respect for people choosing for some good reasons a mirrorless system (which btw is already two years old) additionally to a DSLR? How about rethinking your conception instead of talking about a system you were briefly looking through at the last photokina two years ago? A lack of personal experience apparently doesn't prohibit strong opinions. But that doesn't make them well-based.

Using EVF for over two years now I never felt limited in the way that I could not take the picture or had to change for the OVF. It's not perfect, but most of my concerns against EVF turnt out to be prejudices or outdated. I don't want to pull anybody "to the other side" and I'm not participating on camera sales, keep your DSLRs as long as you like. I also will not sell the D850, mainly because Nikon failed in making a proper Z battery grip. But each time I use I feel limited. My focus and recompose tryouts never gave me accurate sharpness in critical situations, so I changed my AF-technique and get more keepers, but still not as much as with ML.
