EVF cameras outclass optical viewfinder cameras in every way. I bought a Sony A7R II a couple of years ago to try (my first ever EVF camera), and I was blown away. I sold all my optical viewfinder cameras, and will never use those obsolete dinosaurs again! ...
I bought my first EVF camera when Panasonic introduced the G1 in 2008. Also tried the Olympus E-P2 with the accessory EVF. I've also owned and used the Fuji X-T1 and X-E2S and the Olympus OMD-E1. A few others belonging to other people along the way. I've
really tried to find an EVF that I liked and it simply hasn't happened. In addition to my own vision limitations there's just this inorganic look about the subject, a loss of contact. It's like paying to attend a live music concert and then having to watch the performance on the big screen rather than watching the musicians directly. I can't explain it any better than that other than saying it's not comfortable for me to use.
