Very good

Way to dramatic photography
Initially I was skeptical about buying this expensive filter but still gave it a shot. The results are amazing, specially when you use a flash, the background gets dark and the pictures look dramatic. Needless to say that it will work great for long exposure shots too.

Will buy again.
This Nd filter is awesome

Wonderful for the price
Looks almost as good as more expensive solutions. There is a little bit of banding but it is not noticeable unless you are capturing a very bright or high-contrast scene.

Great replacement for lens caps
Best cheap functional lens cap

Great filter for cinematic video
Gives great versatility to video shot on Moment lenses. Saves a ton of time and lets me focus on the action and story.

Follow the directions
As long as you use it as intended and you aren't going passed the stops on the side,You don't end up with that cross mark you see in the videos. I've definitely been able to get the desired smooth water shots with my shutter speed at less than 2.

It is exactly how it was described
I use the filter mostly for my Galaxy Note 9. The filter is just perfect and made a huge difference on my photos. I am very amazed with the clarity of my photos. It is a good buy.

Cost effective/quick means to the same end
I had researched the qualities and capabilities of an ND filter. What I did not like was that each 'level' of ND effect were a separate lens and to buy a range of them would cost money and add bulk to your camera bag. When I found this variable ND filter, at a reasonable price, I ordered it. I like that, with one lens, I can change the density quickly by a simple rotation of the lens. Where as, if I had a set of ND filters, I would have to guess what effect I wanted, select a lens from the set, screw it on and hopefully not miss my shot. True, for a tripod set up and all the time in the world, you could try different lenses and compose your shot but most of my work is wildlife and at-the-moment shot. A great addition to my camera bag.

FAQs
A
From 1-5 stops, there will be a slight X cross for lens under 24mm. An X cross will appear at the highest stop and can be removed by rotating the filter ring, which is a normal situation instead of a quality issue.
A
Tested with Nikon Z 7 and Nikor 14-30mm Sline, dark corners are not obvious for 14mm and no dark corners for 16mm.
A
As K&F Concept ND2-ND400 filters adjusts the amount of light that can pass through with polarizing glass, a colour cast can't be avoided for all the variable ND filters on the market. However, K&F Concept variable ND filters are made by the best coating technology, which reduces the effect of the polarizing film on image color. *Based on our professional test, the colour cast of K&F Concept ND2-ND400 filters is around 290k while the industry standard is 500k.
A
To avoid dark corners, K&F Concept ND2-ND400 filters are designed in ultra-wide construction so the front side of the ND filter is one size larger than the camera lens. It is recommended to use a lens hood of a larger size.
A
First, K&F Concept ND2-ND400 lens filter allows changing shutter speed based on the effect you want with the best sensibility and the same aperture. Second, K&F Concept ND2-ND400 lens filter allows creating a blurred background with a large aperture while the shutter speed remains the same. Third, K&F Concept ND2-ND400 lens filter is designed to prevent overexposure and maintain image purity and quality at the same time. *Like a zoom lens, the variable nd filters are suitable for multiple shooting situations. If you're looking for perfect image quality, a fixed ND filter is recommended.
