Great filter . Using this on my Zeiss 16-35 f/4 on a Sony a6500 for film use. The picture and build quality of the filter is good value for money , made with quality glass . My only complaint and this is pretty big deal for me is my lens hood will not fit while using this filter . It’s one or the other for me now , which is a bummer.

The vignette with this filter is a serious issue and I wish that I had read about this issue before purchasing it. You can see the issue in the attached photo.

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.

A very good filter. It’s very smooth and has a stopping point. I used this on my sigma art lens for a shoot. No vignetting!

Pretty damn good. I’ve shot with it several times over the past week or so. It’s awesome. Great quality filter.

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!

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.
