Mechanics of a Camera (SLR)Reflex refers to the way light travels from the subject to the viewfinder. Light comes through the lens and is reflected up by a mirror to a focusing screen that is found just below the camera viewfinder.A groundglass is located at the base of the pentaprism. The pentaprism is a box of mirrors which correct the image so that you see the scene as it looks to the eye. Without the pentaprism the scene would appear upside down in the viewfinder.
