Haida NanoPro MC ND32000 / ND 4.5 Full Filter Optical Glass (75x75)

The Haida NanoPro MC NDx32000 has been designed for use on long exposures or reduce the dept of field. It is primarily used to control the image on longer exposures allowing use of much slower shutter speeds.
The visible effects created by using longer exposures is the effect of motion blur on any movement within your pictures, such as clouds, waterfalls, seas and rivers.
The filter is fitted with a gasket perimeter, which creates a seal between the filter holder and lens, thus reducing light spillage around the sides of the filter.
