This filter is well constructed with physical stops from the lightest to the darkest setting. This means no more endless spinning of the filter and therefrore prevents the dreaded "X" discolouration.
Because of this it's not the darkest filter (about 4 stops) but its good for most situations. Also the front of the filter is threaded (many arent!) so it is possible to add a lens cap or another filter, for example on rare occaision in really bright conditions I've added solid ND filter to it. Comes in a protective hard case too, great for when you're on your travels or storage. Overall, it's a quality item especially at this price!

This is my second of these filters I have purchased. Got another lens so needed a different size. Love these filters, easy to use, no 'X' and no colour cast. My photo's and videos benefit greatly from the use of these great Products. Buy with confidence!

Got this for my gh5 for when I went to Cyprus.
Was literally a life saver with it been so sunny. Didn't notice any colour issues when editing to footage.
Comes in a plastic box feels a bit cheap but does the job for keeping it safe.
Would reccomend to anyone not wanting to spend a fortune on a variable ND filter.

I was really worried I'd see an X in my footage when using this ND filter as other people have complained about this but I can confirm that there are absolutely no issues with the filter. I love the fact that is has a hard stop. It's so easy to screw it onto the lens and take it off. I'd definitely recommend it to anyone!

Came in a beautiful box
Smooth and high quality
I'm very happy about the product
Thinking to buy one more for another lens.

Este filtro lo uso con un lente 56mm f1.4 para fotografía de retrato, sesiones, etc. Y funciona perfectamente, no pierde calidad en las imágenes. Así puedo tomar fotos aunque haya mucha iluminación sin pasar de 1/250s

This is a must have item in your camera bag and for a fraction of the cost of other brands of Variable ND filters.So far I have tested it with several lenses and 3 different cameras using step down rings in low light and bright mid day light from the lowers ND2 all the way up to DN32 and so far have not seen any X pattern. A huge issue with many a variable ND filter, even with the really expensive ones.Color cast is insignificant too, but like ALL lower end ND filters there will be a color cast, hell even a $500 one will have some kind of color cast, again at a fraction of the cost to have a barely noticeable color cast, or at least one that can't be easily corrected in LRThe only real issue with this is if you are using the filter with the same thread size as your lens the vignetting is a little bad at both extremes, unless you zoom in with your lens. SO I bought the 77mm one for my old Canon 24-105 that has a 77mm thread on a full framed camera, and at the extremes of the ND filter and when my lens is at it's wider focal lengths the vignette is somewhat an issue, again a vignette is still easier to work with than the dreaded X pattern.Now adays I am shooting with Sony mirrorless and every lens I shoot with on my full framed camera is less than 77mm threading and the vignetting is no longer an issue at any range of the filter and at any focal length of the lens and I have been shooting the dang thing A LOT with my Sony.Crop sensor cameras should not have the vignetting issues with this filter.Above are some of the photos I have taken with the filter including my Canon 5D series and my Sony A7R series. The first 3 are of my Canon and the second 3 are my Sony

It took only 22 days to reach my doorstep in India. The product feels outstanding and my experience was 10/10. Fully satisfied.

Images and video look even and no color distortion

This filter is great, feels well built, and comes with a sturdy and protective case. I noticed very little color shifting for video work and the range of ND is good.
