Q&A
Q1: How does ND2-400 work?
A1: Two sets of polarizers with high transparency are used to control the amount of light entering the lens through the filter.
Q2: Can the original lens cap be used for ND2-400?
A2: In order to prevent vignetting, the ND2-400 is designed with an ultra-wide angle structure. The front port diameter of the filter is one size larger than the original aperture of the lens, so the lens cap needs to be one size larger than the lens aperture. For example, the 77mm ND2-400 Need to use 82mm lens cap.
Q3: Does ND2-400 have a color cast?
A3: Due to the use of polarizing film to control the amount of light entering, color cast is a common phenomenon among all adjustable NDs on the market. KF relies on mature manufacturing technology and fine coating technology to minimize the polarization effect of the polarizing film.
Q4: Does ND2-400 have vignetting?
A4: Using Nikon Z 7 and Nikor 14-30mm Sline test, 14mm vignetting is not obvious, 16mm has no vignetting.
Q5: Does ND2-400 have a cross shadow?
A5: The maximum aperture of an ultra-wide-angle lens below 24mm will have a slight cross shadow in the 1-5 gear dimming. The longer the focal length used, the smaller the effect of the cross shadow. There will be obvious cross shadows and vignetting in the large gear of dimming. If you continue to rotate the shadows, the shadows will disappear naturally, which is a physical phenomenon and not a product problem.
Functions of ND2-400
Functions of ND2-400
1. Under the premise of ensuring the best iso and not changing the aperture, the shutter speed can be freely changed according to the desired effect
2. Under the premise of maintaining the same shutter speed, a large aperture exposure can be used to create a blurred background effect
3. Even with a shutter speed of 1/8000 sec, the maximum aperture of F1.4 or F1.2 may cause overexposure. In this case, the ND2-400 can easily eliminate overexposure and retain highlight details.
4. Adjustable ND has more applicable ranges and applicable scenarios. If you pursue the ultimate picture quality, it is recommended to choose a fixed value ND.

Sturdy aluminium product
Good quality product with very good metallic feel.

Made the purchase receni so I'm still testing it.

One thing I am worried about is not to over spin it as from other reviews I have seen some of them distort the image.

That exceeded my expectations!
All of the reviewers say the feel of this filter is top notch, but some seem disappointed with the functionality. Maybe I'm just lucky, but the finish and precision are spot on. I bought two different sizes and both are great quality and well aligned polarizers (the elements that make it up at night) which means there are no "cross shadow" (XS) issues. Well that's a lie! At some point there will always be an XS, but for me it was just before the 8th (last) aperture when used with a wide angle lens (16mm APSC). This means that almost the entire range can be used, everything you could want with a variable ND filter.
That exceeded my expectations! That exceeded my expectations! That exceeded my expectations! That exceeded my expectations! That exceeded my expectations!

Great filter - good value for your money.
I bought this filter to reduce the amount of light entering through the camera lens and to improve the overall look of outdoor video. The filter lets me control overexposure and it works very well. The filter attaches easily to my camera lens. The filter also come in a protective plastic case and a cleaning cloth which is a nice touch. I’ve come to expect good things from the K&F Concept product range and this is no exception.
Great filter - good value for your money. Great filter - good value for your money. Great filter - good value for your money.

Love the versitality of this
I absolutely LOVE this filter. It stays on my zoom on my camera all the time!The handle to change filter level is easy, the filtering itself looks great and lets you get that perfect shot without switching filters. We took a trip this weekend and this filter never left the lens. If you take pictures outdoors, do yourself a favor and pick this up. No fiddling with any filters in your bag. Just turn dial it in and go.

Filtro ND variabile K&F buon filtro per paesaggi
Ho acquistato il Filtro ND Variabile K&F Concept Densità Neutra Variabile ND2-ND400 (9 stops) con Anello Rotante per poter utilizzare un ND veloce e con diverse densità.Il packaging è fatto molto bene, contenitore solido e poco ingombrante. Il filtro di vetro risulta leggero e l’anello per aumentare/diminuire la densità è fluido. Non presenta blocco fine corsa.Per testarlo al meglio l’ho provato con tre ottiche differenti su fotocamera Nikon D750 (full frame) : 20mm, 35mm ed 85mm.- 20mm: nelle foto eseguite con il filtro non si nota particolare perdita di nitidezza, introduce una lieve dominante calda facilmente risolvibile in post-produzione. Per quanto riguarda il problema X-shape si presenta abbastanza marcato utilizzando il filtro oltre la ghiera segnata. Utilizzandolo invece all’interno della marchiatura segnata il problema è poco presente. Si veda immagine allegata.- 35mm: nelle foto eseguite con il filtro non si nota particolare perdita di nitidezza, introduce una lieve dominante calda facilmente risolvibile in post-produzione. Per quanto riguarda il problema X-shape non si presenta così marcato come nella precedente, ma è presente una vignettatura soprattutto nell’utilizzo al massimo effetto. Si veda immagine allegata.- 85mm: nelle foto eseguite con il filtro non si nota particolare perdita di nitidezza, introduce una lieve dominante calda facilmente risolvibile in post-produzione. Per quanto riguarda il problema X-shape e vignettatura non si presentano in maniera rilevante. Si veda immagine allegata.Otticamente quindi il filtro si presenta di buona fattura e fornisce ottimi risultati, avrei preferito però un inizio e fine corsa con blocco in maniera da evitare possibili errori. Considerando inoltre che K&F produce filtri di altra tipologia ma con attacco magnetico credo potrebbe essere un plus ulteriore per questo filtro.Il rapporto qualità/prezzo è corretto in base alle prestazioni fornite.Allego ulteriori foto del packaging e di due scatti al mare.

Useful for long exposure with a smartphone
Wide diameter and easy to adjust. Comes in a protective box for transporting it.
I fancied trying some long exposure shots with my smartphone. I already had bought fixed filters but there was no adjustment to them without shooting through several layers of glass. Thought I'd try this one as it was adjustable. It's like having two polarising filters mounted together and is infinitely variable from light to very dark just by twisting the frame.
It does take a bit of fiddling and post editing to get some natural colour back, but it did what I wanted it to and am waiting for some better weather to spend a bit more time tatting with it. Its is big enough to cover all the lenses on the back of the phone with room to spare for hand movement though you do need to hold it very close.
Obviously a tripod is needed and a steady hand is helpful.
It was suitable form my needs and I recommend it.

Excellent photographic yield and material conservation
I tried this filter on my Sigma 17-50 and the result is really amazing. The product looks great in its really high quality packaging and is easy to carry in your pocket. The photographic rendering is of a high standard for a low price. I find the tongue very interesting, it allows a better grip at work.

You can feel some vignette, in this filter it is from half to max. Everything else, like the picture quality, sharpness, fits the lense etc, is really good. It is'nt bad for the value of this amount money!
I dont have experience with other filters.

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.

Tested with Nikon Z 7 and Nikor 14-30mm Sline, dark corners are not obvious for 14mm and no dark corners for 16mm.

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.

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.
