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.

Value for Money
I had been meaning to buy a variable ND filter for my 24-70f2.8l for a while. When I heard about K&F filters; having tried a 3xnd filter kit pack that I was impressed with; especially at the price. I looked at K&F's other products and found this more than reasonable price ND filter and had to give it a go.

The filter is shipped from China; so its not something to order if you are in a rush - but when it did arrive I was blown away by the quality of the presentation. The filter was packaged inside a well designed; expensive looking, cardboard outer package and then a hard plastic inner with a foam sheet to allow it some protection.

On opening the pack one disadvantage to this filter immediately manifested itself; the front element isn't 77mm so your lens cap won't go back on the lens with the filter mounted. The filter mounted smoothly onto my lens. The variable darkness is achieved by rotating the front element; as you would a circular polariser. The K&F filter spun smoothly but with enough resistance to keep the darkness you set so knocking it won't change the setting. One disadvantage to the design is the filter doesn't have coded ND values so there is a bit of guesswork to get the right exposure for stills.

I tried the obvious and took an image of a plain white wall at various ND settings; and there was some minor differences in the brightness of the photo - it was a bit lighter at the edges of the frames. At its darkest on long exposures; the 6d went red shift but this is correctable in Lightroom (and made much easier if you use a colour checker passport.) If you zoomed in on the plane white background you could see some variations in darkness; and ultimately pixel peeping at maximum darkness a mesh. That said taking pictures of something more interesting than a wall the effect was lost in the detail of the image.

I rarely shoot video so for you dear reviewer; I shot some test video of the same white wall. I don't have any fancy video editing software and just watching the video back in lightroom; the darkening effect was pretty uniform across the photo. As with stills if there were any criticism it is very minor and that the corners show up brighter than the centre of the frame. The majority of the frame being uniformly dark. There was no patterning showing in the video.

Using a standard ND filter definitely gave a more even darkness to stills but I am planning 3 long trips this year and carrying 5 ND filters everywhere felt like a chore. Now I just need one. If i could I would ding 1/2 a star for the front element size not being 77mm but its a minor inconvenience in the scheme of things.

Very good value, should fit any camera with the correct lens dimensions.
The filter is exactly as described,easy to fit, feels well constructed and comes in a sturdy case.As far as I can tell it does not add any innacurate colour cast as some cheap ND filters do.I bought a size to fit my largest Olympus pen f lens( which it does with no problem) and I purchased some low cost lens ring adaptors so that I can use it on any of my lenses(I did the same with a good quality polarising filter).

Great quality for the price!
K&F has delivered again, good value for money. I was looking for a good quality variable ND filter for my lenses and this one does the job. I bought the largest size. Got a nice tote bag. Image quality is great.

Oh this thing is brilliant !
Works exactly as expected.

I use this on my APS-C Camera. Sony ZVe10 w/ Sigma 16mm f1.4

Perfect for getting that optimum shutter speed in the brightest of sunshine - no issues here at all. Just mount and twist.
Also, if you want to get a longer exposure during the day, you can put this guy on to get some dope water fall effects.

Love how simple and effective it is honestly.

K&F Concept 77mm ND2-400 filter
K&F Concept stands for quality. I already had their other filters in the kit, albeit quite old and with several years of service behind me. Due to an upcoming photo tour of mine, I have decided on something new and have always relied on it.

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.
