The mirror reflects the image onto a ground glass where focus and framing can be evaluated. Photography Stack Exchange is a question and answer site for professional, enthusiast and amateur photographers. Parallel Standard The parallel interface standard is a well-established standard that provides a wide range of acquisition speeds, image sizes, and pixel depths. Since most EVF are much lower in resolution than the sensor, it is hard to judge best focus by sight, requiring the use of focusing aids like peaking or focus magnification.
