Disappointing in that even at its max setting I can’t take exposures of more than a second or two.

I use this for video and man it is amazing. I've always bought the cheaper $20-30 ones and thought they were good until I bought this one. Will definitely keep buying these for future lenses!

Filter is not wide enough to accommodate even a standard zoom. I have it mounted on a Sony 18-105 f/4 G lens paired with my Sony a6300. In photo mode, all four corners have a very HEAVY vignette. The vignette is visible from 18mm all the way until about 50mm. 18mm isn't even considered wide - angle on an APS-C Camera. The build quality and image quality itself are very good, however, the vignetting renders the filter unusable. Avoid this product if you plan on using it with a lens wider than 50mm.Update: K&F Concepts offered to send a fixed ND 1000 filter plus Step down filters so I am able to use an ND to take photos. I appreciate the help that they offered me so I updated the rating of this product. This 72mm Variable ND filter is very sharp and has no color fringing. If the vignetting issued gets resolved then it would be a near perfect product - especially for the price. Good customer service but subpar product.

I love this filter great for Photo & video.But at 10mm on my 80D Crop sensor it casts a shadow above.if I zoom in a bit like 14mm it goes away.NO X, No Color cast. Great Filter... As Advertised. and Great Build...
