Explanation of "X" cross issues: "X" cross on images is a common issue with wide angle lenses and variable ND filters. Physics limit the capabilities of variable ND filters on wide angle lenses. There is no problem with the quality of our products. When you enter the edge of the max range,the "X" issue may appear on yout image.Because you are using it beyond its capability according to the laws of optical physics,which will inevitably cause this phenomenon. If you want to use ND filtration at wider angles, you'll need to get a ND filter (or multiple filters) with a static density. Package Include: 1 x 77mm Ultra Slim ND2-ND400 Filter 1 xpacking box
