For most scenes they look pretty similar, but a solar eclipse is a very unique situation with incredible dynamic range. I expect that the actual photos each camera will produce will be quite similar, but for anyone who has taken a picture of a solar eclipse already knows, the picture doesn't come anywhere near to what it actually looks like through the optical viewfinder (or binoculars). So my question is whether the EVF will have similar limitations, such that you're perhaps better off viewing the eclipse through binoculars while taking photos with the mirrorless camera, just so you don't miss out on the full experience.
Yes, the EVF will have the same limitations as the captured images. Probably the "OVF Simulation' mode of the R3 will be better in that regard, but it's still not going to match an OVF in that situation. Agree that viewing with binoculars would be better, but I think that's generally true anyway for both solar and lunar eclipses.
