Fixed round filter better than variable
The variable ND filter has a defect in the direction of the minimum and maximum values and forms a kind of cross and vignettes in the image. With this fixed filter, the problem is not there. The filter does not change the image and the colors (a positive thing, very positive), but only reduces the amount of light that allows a long exposure and smoothes the water, which increases the shooting time, the silk effect. The only flaw with these filters is that they are not polarized, but at these prices I do not think I can find them 2 in 1.
