The Hoya 62mm Pro ND16 Filter provides a 4-stop light reduction (ND optical density of 1.2) and is part of the Hoya PROND series, designed for both still photography and HDSLR video. Featuring ACCU-ND technology, it delivers a truly neutral color balance, eliminating noticeable color casts in your images. The series includes 10 filters offering light reductions from 1 to 10 stops, with Metallic ACCU-ND coating ensuring consistent color neutrality across all densities. This allows users to set their white balance once and maintain color accuracy even when switching filters, making it a versatile and reliable choice for managing exposure in varying lighting conditions or achieving creative effects like motion blur or shallow depth of field.
