What I'm wondering specifically, is how the image would look in the viewfinder for a mirrorless camera, if you compared it to a DSLR side by side. The EVF is giving a 'TV screen' view of the scene, whereas the DSLR is showing you the real McCoy. 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.
