This lens hood is designed to replace the manufacturer branded version. A dedicated lens hood such as this, is specifically designed to match a lens or a number of lenses. Please take care when purchasing a lens hood for your lens, as some manufacturers have produced multiple versions of lenses with subtle changes to the lens model numbers and these lenses sometimes use different lens hoods. Just because the lens hood is designed for one lens does not mean it will fit a different version. If in doubt please check the manufacturers website to ensure you are purchasing the correct lens hood. Box Contains JJC LH-RBC Lens Hood for Pentax PH-RBC 52mm for 18-55mm F3.5-5.6 Lens x 1
