98.) detachable viewfinder-system for being able to change from OVF to EVF
or -> 99.) *hybrid viewfinder ("pop-in"-EVF)
I guess that goes for lots of other people too, who are not tooo special and would only need 1fps but 120MP.
Just wanted to say: I dont really feel the need for EVF.. though I think it would be cool to have one.
BTW: try a Sony A9 and see that you will have a hard time
recognizing any viewfinder lag.
no one can deny its not real-time... but nearly.
