Hello! This ND2-400 filter is made of high-quality Japanese optical glass with 32-fold nano-coatings.

All variable ND filters have this problem: the larger the focal length used, the less the cross shadow is affected. In the large light reduction gear, cross shadow and vignetting appear obviously. As you keep rotating, the shadows will naturally disappear. This is a physical phenomenon, not a product problem.

From 1 to 5 stops there is a slight X cross for lenses under 24mm. An X cross will appear at the highest stop, which can be removed by rotating the filter ring, which is a normal situation and not a quality issue.

There is a front thread that allows another filter to be mounted in front of the Black Mist filter, as long as the two larger diameters are the same. For example, the filter is 67mm, then you need to install 72mm

The cover cannot be installed. In particular, to avoid the problem of vignetting, the filter increases the opening of the clear light, and the outer diameter of the frame is also increased.

No, there is no structural limit.

To avoid dark corners, K&F Concept ND2-ND400 filters are designed in ultra-wide construction, so that the front of the ND filter is one size larger than the camera lens. It is recommended to use a larger lens hood.
