optical viewfinder

Definition: Type of viewfinder that shows subject directly, through lenses, rather than via a monitor screen such as the LCD screen common on digital cameras. * Preferable to LCD screen for framing shot because it takes up no power; however may introduce parallax errors unless it is a single lens reflex (SLR) design. * Also known as direct vision viewfinder.
