The PRO1D ND filter features PRO1D ND coating, which emphasizes flat transmission characteristics. It is a high-precision ND filter with extremely high neutrality and excellent color reproduction. It achieves light reduction without affecting color. The outer edge of the glass is blackened to minimize internal reflections. The filter frame features knurling (non-slip) for easy attachment and removal. Its thin frame is compatible with wide-angle and telephoto lenses. ND4 reduces light intensity by 1/4, equivalent to two stops of light reduction. ND8 reduces light intensity by 1/8, equivalent to three stops of light reduction. ND16 reduces light intensity by 1/16, equivalent to four stops of light reduction. The lineup ranges from 49mm to 82mm.
