The Fujifilm 67mm Protector Filter is designed to protect the lens on the Fujifilm S1 digital camera from getting damaged. The filter attaches via the filter thread on the lens & features an advanced Super EBC (Electron Beam Coating) to control ghosting & flare. 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.
