Q
Q: Why is there a black cross?
Answer Question
A
Answer: All adjustable ND filters will have this problem, the larger the focal length used the smaller the impact of cross-hatching. There will be obvious cross-hatching and vignetting in the large stop of light reduction, continue to rotate the dark shadow will disappear naturally, which is a physical phenomenon, not a product problem.
