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