Variable ND filters are primarily used for filming, since long exposure times have to be used there. In order to have the right exposure at all times, it is important to be able to adjust the ND filter. Inexpensive variable ND filters usually have a yellow cast. Of course, this falsifies the white balance and the image effect. Unless you want it that way. I still like to use the variable filters. Especially with long exposures on the water. But I've often been annoyed by the distorted color effect. The ND filter reviewed here is clearly not one of the cheap filters. It also comes in a very nice case when it arrives and it even has a handle that you can use to adjust it very comfortably on the camera. As you can see from the pictures, the color effect does not change. Aperture and exposure time as well as ISO were all the same. Only the filter was adjusted. I think you can see the quality of the filter well.
In general, I would like to warn against turning the filter on too tightly or slightly crookedly, or using it at strongly changing temperatures. Then it happened to me more often that I couldn't get the filter off anymore. That was only possible with the right filter clamp.
I haven't had any problems with this one though.
I like him very much. But that should also be the case, it also costs significantly more than the inexpensive league.
5 Stars.
