The Olympus LH-55B Lens Hood is a rectangular lens hood designed to reduce unwanted lens flare and ghosting caused by stray light entering the lens from off-axis light sources. In addition to improving image contrast and color accuracy, it provides an added layer of physical protection for the front element against accidental bumps, scratches, and everyday handling. Constructed for seamless compatibility with the Olympus Zuiko Digital ED 9-18mm f/4.0-5.6 lens and the M.Zuiko Digital ED 12-50mm f/3.5-6.3 lens, the LH-55B offers a secure fit while maintaining proper coverage throughout the lens' field of view. Its lightweight, durable design makes it an ideal accessory for photographers seeking enhanced image quality and lens protection during travel, outdoor, and everyday shooting. | Olympus | | LH-55B Lens Hood for 9-18mm and 12-50mm Lenses Reduces Stray Light and Enhances Image Quality | Black | Best Buy
