I thought of this the other day while bent over my monopod for a couple hours trying to photograph fish on a steep creek bank. Why can't we have say smallish half frames like reading glasses we can wear on the end of our nose so we can either study the EVF or look over them at the subject? I missed a lot of shots with the fish cause I could not effectively watch the view finder and the subject area at the same time given that I was using long tele and had a very small view. ( rear screen no good as I had to hold the camera low ) I often had a few fish close, not moving very fast but then some better subject might be only two or three feet away but only in range for a couple seconds. Could be good for birds too.
