The Pop-Up Pro Shade is designed to attach to your Canon 20D using the existing eye piece and slots around its display. It easily snaps on and off, and features an optical clear glass to protect the camera’s screen. The simple pop-up design allows for easy opening to block the glare. Buttons on the Professional shade are aligned with your camera, to reduce the wear and tear on delicate parts and components. Color and design also matches your camera model.
