The Hoya ND 16 reduces light by the equivalent of 4 stops. For photographers, ND filters mean precise control of the amount of light passing through the lens to allow greater creative control of exposure. For video content creators, ND filters are very helpful when setting shutter speeds to adjust the frame rate while maintaining the depth of field of the footage. Thanks to ACCU's leading ND technology, the image is not negatively affected by color shifts that can occur due to inferior materials, poor manufacturing quality control or problems with leakage in the infrared part of the light spectrum. The last problem is the most important in photography and videography today. With HOYA's exclusive ACCU-ND technology, a uniform reduction of light in the visible and IR spectrum is achieved. As a result, the photographer does not have to worry about color shift problems when using HOYA ND filters under different shooting conditions.
