>>3375541It wouldn’t really be an EVF. Just a viewfinder for framing with focus/exposure indicator.
Pic related; kind of how I’m envisioning it. Shutter, iso, battery, frame counter along the bottom, match needle aperture/meter on one side, and focus indicator on the other side (or maybe down below with the other indicators). The little arrows would indicate if you’re focused too close or too far, with the center dot being in focus. Circle overlay in the middle of the framelines to indicate where it’s focusing.
