Focusing hood for use on a digital camera
Abstract:
A telescopically extendible focusing hood which improves the viewing of the LCD screen of a digital camera in bright surrounding light. The focusing hood can be fixed to the rear wall of the camera, surrounding the LCD screen. The focusing hood preferably has an anti-reflection-coated enlarging lens or glass disk which covers the entire cross-section of the focusing hood in parallel to the fixing plane. In its extended state, the focusing hood can be used with a single lens in the manner of a 35 mm camera finder. When the enlarging lens is pushed in, the focusing hood can be used with two lenses for assessing the image.
