The quality of the variable ND filter ND32- ND512 is very good made from very good materials.

I am impressed with the variable ND filter I was not expecting too much for this price BUT I am happy to have been proved wrong.

Rotating the filter is very smooth and easy I can just about turn it with one finger it really is effortless. You do not have to rotate it much to go from ND32 to ND512 which I like a lot and great if you’re trying to do this quickly.

Comes in a nice protective box not the normal square I have gotten with so many other filters/brands this is circular and see through so you know if the filter is in case without opening it or giving it a little rattle.

I can confirm so far I have not had any phantom X showing up in my pictures or on the display when I have been changing the ND values this really did impress me and I was expecting to see this at this price range as I have with previous filters at this price and some which cost more than this.

If I really had to find faults I have two which are minor and not that big of a deal for me the first is with the protective case I would have liked it to have some padding or something in the inside to keep it firmly in place to stop any movement. My second this is probably just me but I am not that keen on the range starting from ND32 I would have preferred from the lowest possible at a push from ND8.

Also so far I have had no issues removing this filter from the lens which can be a problem with variable filters

Overall I am happy with this variable ND filter.

I use the filter both for filming with DSLR and for long-term exposure during the day with an open aperture, especially when filming, it is simply beautiful with an open aperture. The ring can be easily turned. The sound should be recorded externally, because the ring clicks quietly in the intended positions .. The packaging is great for transport and can withstand the attacks of my 1 year old daughter. The image quality looks good. At least I could not see any tint or other disturbances. I am very happy with the ND filter.

Works exactly how I hoped it would. I mainly bought this so I could do more filming outside with a lower Aperture setting. This is perfect for just that. Tested it out as soon as I got it. Attached are 3 photos and 1 video that displays the quality of this item. The first photo is with the lowest ND filter setting (ND 32). The second photo is the highest setting (ND512). And the last photo is with no filter on the camera.

I ordered this filter for my Canon 800d and it works like a charm. The packaging it came in gives you an idea of ​​the product's first-class design. Since this is a variable Nd filter, I can leave it on my lens as the filter does not have to be removed to get more light. I had high expectations for this filter while ordering, and the results are better than my expectations. The filter ring is very smooth and does not jerk when recording video. There were no dark spots on the pages of my photos that I have experienced for any other filters, the Prime delivery was very fast and the product arrived safely in one day. I would definitely try other K&F Concept products as the ND filter meets the requirement.

I bought the filters to expand my collection. I have now found the right ones. Delivered very quickly and came in a very stylish packaging with magnetic closure. The filter itself was packed in a high quality plastic box. Using adapter rings, the filter was quickly attached and did a great job. Easy to use and great workmanship, I can recommend it to anyone looking for a filter.

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

The Nd filter is well constructed using metal and glass. The optics have a 18 layer coating to reduce flare and smudges/scratches. It has a stopper to let you now when you are at maximum and minimum which is more than can be said for most! No horrible X either which is great. There is hardly any colour tint from the filter and what there is is very easily corrected.
The image I've provided is one I took using the 72mm variable ND filter.

If your looking for a variable ND filter to add to your kit you won't be disappointed with this one. It's a no brainer.

The marking on the side from ND2 - ND32 is fixed so you can't go past them and accidentally get a cross on your video footage.

Can't notice any difference in quality when comparing two sets of footage with and without.

It's a must to keep one of these in your camera bag if you do video and will also help if you do photography and want to do long exposures.

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!

in past 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.
