The mirrorless advantage
Get an accurate picture of your final image from the viewfinder
Unlike EOS DSLRs, EOS R cameras don’t have a mirror inside to bounce the image up to an optical viewfinder. Instead, they have an electronic viewfinder that’s essentially a smaller version of the camera’s rear display, and this can show the Live View feed from the sensor or the camera menus, just like the main screen.
There are a number of advantages to this design, and couple of potential drawbacks. The big bonus is that you can see the subject or scene as the camera sees it. By that, we mean with image processing settings such as white balance and Picture Style applied. Of course, if you shoot Raw files then these settings aren’t applied to the image that’s saved to the memory card. Even so, there’s a real benefit to being able to preview an accurate image – and it’s dead handy for judging how an image will look when you want to shoot in black and white.
