reflex camera
a camera in which the image appears on a ground-glass viewer (focusing screen ) after being reflected by a mirror or after passing through a prism or semitransparent glass; in one type (single-lens reflex camera, or single-lens ), light passes through the same lens to both the ground glass and the film, while in another type (twin-lens reflex camera, or twin-lens reflex ), light passes through one lens (viewing lens ) to the ground glass and through a second lens (taking lens ) to the film, the lenses being mechanically coupled for focusing.
