The electronic viewfinder is, of course, the big deal with a mirrorless camera and the EOS R gets the current state-of-the-art 1.27 cm OLEDtype panel with a resolution of 3.69 megadots. The magnification is 0.76x (with a 50mm lens) and the coverage is 100 percent. The eyepoint is 23 mm and an eyepiece strength adjustment is built-in. The panel itself is adjustable for brightness (over five levels) and colour balance (with four settings). A proximity sensor in the eyepiece allows for automatic switching between the EVF and the monitor screen.
