Hoya Variable density filter X3-400, 67

The variable density filter enables you to adjust the brightness of a scene giving greater control over exposure settings during both still photography and video use. The filter reduces the amount of light entering the lens by approximately 1/3 to/400th of its original level. Adjustment is done by using a rotating inner filter ring.
