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!

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

For the price this is an excellent quality filter. No problems with picture quality. No chromatic aberration or distortion. Easy to use. The only issue is that the front filter thread of the filter itself is slightly larger than that of the lens. This means that the lens cap that comes with the lens won't fit on the front of the filter. Only been using it for a few days but already getting some great results. Would definitely recommend.

Great and flexible ND filter. At ND32 light vignetting on corners. For price great deal.

I have used other variable ND filters in the past and whilst I didn't ever come across any real issues with them, I did brake my last one when dropping it in a car park!! So I bought this one having already been very impressed with the K&F square filter kit, I thought I would try them again and they haven't disappointed. I mostly use the VND filter when filming (the square kit is not ideal for filming) and in the summer it's a must-have piece of kit. The case that comes with the filter is really handy for chucking in a bag and I know it will be protected. the twisting rings are nice and chunky so its really easy to change the strength which is hand when filming.
The image quality is great with no noticeable colour casting and you don't get the wired X that you can sometimes get with the cheaper VNDs.
With a VND at this quality and price point, I really see no need to invest £300 in one.
My only very slight gripe is that I cant use my lens hood with it and the lens cap doesn't fit as snuggly as it does on the lens, meaning I cant just leave it on.

Fantastic filter with no obvious colour shifts in my resulting photos. Highly recommend this to anyone wanting a no nonsense variable ND filter.

in pI’m always dubious when it comes to filters as I have seen some cheap ones in that past that really degrade image quality. This neutral density film seems really good though.

It seems well made and screws on nicely on my canon EF-M lenses. The twisting adjuster works easily and smoothy and has the various stops marked on it.

Performance is really good too. There doesn’t seem to be a vignette or any other visible marks or patches on photos. The photos seem to be just as sharp and have the same quality as when shooting without the filter. I can’t tell any difference. It comes in a nice holder although this is way bigger then the filter itself.

The range of stops on the filter is good too and helps to slow things down for some major motion blur. It also works well for open aperture video. For the price I am really impressed with the quality and results.ast i got k&f ND filters and i wasn’t happy about them because the had horrible purple colour cast what i couldn’t get ride with photoshop, they were cheap. about £10 for 3 different ND filters with pouch. yeah... price does matter))) lol)) this one is NOTHING close to those what i use to have. it feels like i had ford ka and now i have ford mustang)))
ok...
i use 70-200mm is f4 and 10-18mm both have 67mm
it’s really easy to change from ND2 to ND32 don’t need to unscrew your ND filter from lens, just spin the circle.
there is NO COLOUR CAST. what is most important thing in ND filter. i would say i bought Nisi quality ND filter for twice less than Nisi.
comes in hard storage case not pouch. so when you throw your ND filter in your camera bag , you don’t have to worry about that it will smash. i would definitely buy it again.

I use the anamorphic lens from Moment and FilmicPro to make movies with my iPhone. The K&F 62mm filter is very important to get that cinematic look when shooting at 24 fps. I tried cheaper ND filters, but they had vignetting and poor image quality. With the K&F filter, the clarity is excellent and the build quality is strong and durable. The included case securely holds the filter. This ND filter is great value for money and much better than other inferior ND filters I've tried. I have included photos with the same camera settings without any filters, with a cheap filter and with the K&F filter. I've also included a photo of the setup I'm using. This filter goes perfectly with the 62 mm filter holder of the moment. This is a game-changer for anamorphic video, especially when shooting outdoors. I couldn't be happier with the K&F ND filter. This is superb quality and value! I totally recommend it!
