The Pearstone LCD Screen Protector is a dedicated protector for Nikon D300 & D300s Digital SLRs. Made of 1mm thick polycarbonate, it protects your valuable camera's screen from dirt, scratches and oily fingerprints. Plus, it blocks UV rays while allowing 92% visible light transmission so the images you see are not affected. It is easily mounted to your camera's LCD screen with an adhesive backing. Once it is properly aligned it is smoothed down with a clean cloth and you are ready to go.
