The Hoya ND 32 reduces light by the equivalent of 5 stops. For photographers, ND filters mean precise control of the amount of light that passes through the lens to allow greater creative control of exposure. For video content creators, ND filters are very helpful in adjusting shutter speeds to match frame rates while maintaining the depth of field of the footage. Thanks to the leading ACCU-ND technology, the image does not experience negative effects from color shifts that can occur due to inferior materials, low quality control during manufacturing, or problems with leakage of the infrared region of the light spectrum. The last problem is the most important in photography and videography today. HOYA's exclusive ACCU-ND technology achieves uniform reduction of light in the visible and IR spectrum.
