An EVF, or electronic viewfinder, is a small screen at eye level that you look into to frame a photo. It uses an LCD or OLED display. EVFs are found on mirrorless cameras, bridge cameras, video cameras and some compact cameras.
The sensor records the image from the lens and shows it on the screen in real time. Unlike an optical viewfinder, an EVF can preview exposure, white balance and other settings before you take the picture. It can also display helpful information, such as a histogram or focus peaking.
