ND FILTER
Reduces the amount of light entering the lens, thus decreasing camera shutter speed. Useful for situations where motion blur needs to be created (rivers, waterfalls, moving people) or large apertures must be used with flash to avoid overexposure.

Good overall for the price
It worked well I haven't tested it at the full ND setting because I haven't needed go yet

Outer threading size not listed in the description...K&F took care of me.
Not knowing that most, if not all, variable ND filters have different size threading on the exterior side of the filter, I asked for a solution to my concern. K&F promptly contacted me and provided a more than satisfactory solution.Thank you! Great products (this K&F ND filter and my other K&F polarizing filter) and great customer service.

Quality is key.
It doesn’t fade as dark as those cheaper 10x-400x ones (this is 2x-40x), but it fades well enough for photographic needs and there are NO artifacts or aspheric distortions.Quality is key.
