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.

I love this for video work!
I shoot with the Fujifillm X-T3 which arguably is the best video camera under $3000. However it lacked the variable ND filters that you would find built in to more professional video camera. I needed some more motion blur and lower my exposure when shooting video and this does it amazingly without any noticeable loss of details and colors. For the price this is a very valuable tool in my arsenal. The build quality is really nice with an all metal construction. The ring itself is smooth and allows for a nice variable exposure change. I really dig this ND filter and I think anyone should take a look at this since the image it produces are pretty clean.
I love this for video work! I love this for video work!

Extended warranty
I just received my ND filter today. Excited to get going with it. Tried a few test shots and it seems to work as advertised. However, I am dissatisfied with the company since I am unable to receive the extended warranty. I went to the site and entered the order number from Amazon into the required bucket. Error message came up and my order number was rejected. Therefore, no extended warranty. Very disappointing and frustrating that the Amazon order number is unacceptable to the company!

Buy the largest one
If you look through your lens collection buy the size that fits your largest lens filter size. All you have to do after that is buy some step down rings to make it fit any lens smaller than your largest. This should also keep your wide angle lenses from getting cropped by the filter. The filter itself is awesome. Easy to turn from 2-32. Very easy to use.
