The Hoya 67mm Pro ND Kit is a convenient, one-stop solution for ultimate lighting control; perfect for long shutter-speed photography. Photographers and cinematographers alike are sure to benefit from the ACCU-ND metallic coating technology applied to the front and rear of the filters. The coating reduces the light spectrum (IR included) and delivers a neutral colour balance. Thanks to this you can combine two ND filters. The kit consists of three of the most popular 'ProND' solid Neutral Density (ND) filters from Hoya - ND8/64/1000.
