Fujifilm Protector Filter 77mm Protecting the lens from dust, dirt & scratches, the 77mm protector filter attaches via the filter thread on the lens. Featuring an advanced Super EBC (Electron Beam Coating) to control ghosting & flares, the protector filter has minimal reflection (maximum of 0.3%) so image quality is not affected. The thin-frame design prevents vignetting when using 2 filters together.
