1-9 aperture levels – K&F Concept variable ND2-400 filter is designed for long exposure and motion blur techniques in changing light. Excellent for nature and landscape photography. (Note: New and old packaging will be sent randomly.) Premium glass – made of high-quality Japanese AGC glass, optimal brilliance and distant vision, intense colours and high contrasts. Extremely slim – the ND filter is very slim, the frame is only 7.4 mm thick and has a CNC trapezoidal pattern design. It can increase friction and can be installed or removed anytime and anywhere. Motion blurring – reduce 1-9 aperture levels for dramatic motion blur and shallow depth of field in changing light conditions. Notes: This variable ND2-400 filter is not recommended for use with wide-angle lenses with focal lengths <35 mm. For this ND filter, you need to use a larger lens cap or a larger lens hood.

As for the X-shape problem, it is not as marked as in the previous one, but there is a vignetting especially when used to maximum effect.

The quality/price ratio is correct on the basis of the services provided. I am attaching further photos of the packaging and two shots at the sea.

K&F Concept is synonymous with quality. I already had other filters of theirs, albeit quite old and with several years of service behind them. By virtue of my imminent photographic journey, I decided to opt for something new, always relying on them. I'll show you in detail what are, in my opinion, the pros and cons of their new product. First of all, the packaging is really excellent: the box is made of very sturdy cardboard, even impossible to fold, and then the magnetic opening is very pleasant. The filter is stored in a leatherette case with magnetic closure and not in plastic, which gives the product a finish that we can define as "premium". Inside, wrapped in a protective bag, is the filter. It is a fairly heavy piece, already to the touch it gives an excellent ... MoreK&F Concept is synonymous with quality.

Very thin (and this is good because in this way any loss of sharpness is reduced), waterproof and scratch resistant. Very pleasant (and very useful!) the orange little thing that is used to vary the intensity of the filter itself: the only drawback is not having a limited stroke during rotation, but it is not a big problem, since the ND2 and ND400 are indicated right on the end of the filter itself. In any case, the filter has been constructed in such a way that, even when going beyond the limits, the annoying "X" shadow does not appear. For the moment I've only been able to try it in the city on a rather gloomy day, in the next few days I hope to integrate my review with other shots in the mountains. Who is the filter for? Definitely for those who love landscape photography or for those who have the desire to take long exposures in the city (remaining within the limits of 9 stops): of course, the product is not the cheapest on the market, but just try it for a while to understand which is worth every penny. I'm not a photography professional, but for my use it's just fine.

The K+F Concept Slim 52mm Variable Fader is a great item for several reasons, but its main function is to remove shadows/reflections from water and other non-metallic objects. I was really impressed with its functionality and how well it fastens, and I was equally impressed with its design and ease of use. Like other filters, this one is threaded and you can easily twist it to adjust it to your needs. The filter is also stackable so you can place additional filters or a cap on top, great for additional effects and preventing scratches. Speaking of scratches, using filters also helps protect your lens. So using filters not only creates a beautiful effect, but can also prevent random items from coming into contact with what would normally be an expensive item. I would ...

I would also like to point out the packaging and commend the company for creating something that will keep your item safe using both hard plastic and soft foam. This is probably the best packaging with filter I have ever seen and it really made me happy to see it. Please note that this was supplied for trial purposes and was used multiple times prior to review. As with any filter, you should experiment with it before taking the shots you want to make sure you have it dialed in perfectly. This was a lesson I learned some time ago, and unfortunately the learning curve was steep.

Love it. Easy to use. Points must be used for correct alignment. When you switch to the Min/Max marker, you'll see the "X" you see in some photos. This is purely user error. I've done it myself. What I love about the variable filter is that I can set it to the lowest setting on my lens, set my shot and focus, and then turn it to the maximum setting to take my shot. You don't need to remove the filter to set up a different composition.

So I adjusted the aperture and instead pushed the shutter further and further up to achieve an acceptable exposure. I also had some condensation on my lens when I screwed on the filter, creating a haze at the top of the image. Should have used aperture 11+ and a 1 second exposure time, but the water still mixed well.
After I finally dared to buy and attach the adapter for the Sony ZV1 (unfortunately it has to be glued), I was able to buy this stepless ND filter. The quality is impeccable and I love the adjustability without having to change the filter. The photos are very cool. Well, I still need a little practice, but the first results are impressive.In the video (YouTube) area, the glaring recordings can be avoided by using the filter. I still need a little more experience with the application, but I'm really excited about the filter. You really can't go wrong there.Notes on the uploaded photos: From left to right, low filter, then medium filter and the last photo has the highest filter attached. That looks best in my opinion.
I spent a long time buying a filter because on the one hand I didn't know if I needed something like this and on the other hand because I had already tested a 0815 filter with miserable results and the costs for such a part are not insignificant. The question now was whether I should get several filters or a variable filter. In view of the price, the question ultimately became irrelevant. The first tests were able to dispel concerns that the image quality suffers, as with the filter mentioned at the beginning. The images are slightly blurry, but really only marginally. The weakest position extends the exposure time by a little more than 2. In my experiment (Nikon D7200, Sigma 18-35, K&F variable ND filter 77mm ND2-ND400 with adapter ring) I set the aperture to 2 in ...

The first tests were able to dispel concerns that the image quality suffers, as with the filter mentioned at the beginning. The images are slightly blurry, but really only marginally. The weakest position extends the exposure time by a little more than 2. In my experiment (Nikon D7200, Sigma 18-35, K&F variable ND filter 77mm ND2-ND400 with adapter ring) I set the aperture to 2 in sunshine. 8 raised to expose well at 1/8000 without a filter. With the filter screwed on in the "MIN" position, the shutter speed went up to 1/3200. I turned the filter from mark to mark and came up with the following shutter speeds calculated by the camera: 1/3200, 1/3200, 1/2500, 1/2500, 1/2000, 1/1250, 1/800, 1/400, 1/125, 1/20(X-Cross, but underexposed). As you can see, hardly anything happens at first and the markings also do not allow any ND value order to be determined, which according to the logic of the first point is 2, the second 4 and the third 8.... So it's time to try it out. In the "MAX" position (1/20) the images are unusable because of the X-Cross, but this is really only the case in the absolute max position, and between the penultimate with 1/125 and Max intermediate positions are also possible where I got useful up to 1/30. So a usable ND value of 266 is calculated. This value is now completely sufficient for filming, because who says that I can't set the shutter speed higher than 1/60, which was the rule of thumb in the early days of analogue filming. Enough theory, I think the filter is an absolutely good investment.Unscrewing is completely problem-free and if there was a color cast, it was due to the camera (Nikon D7200).I've uploaded a few pics:1.) 100% topless bottom view with filter at 5th position (1/2000)2.) MIN - position3.) Last usable position4.) Filter to with X-Cross where the camera with the exposure of my camera (Nikon D7200) failed and I had to raise 2 values in post-processing to be able to recognize something.

As for the X-shape problem, it does not occur as pronounced as in the previous one, but vignetting is present especially when using it to maximum effect. See attached image.- 85mm: in photos taken with the filter there is no particular loss of sharpness, it introduces a slight warm dominant easily resolved in post-production. As for the X-shape and vignetting problem, they do not occur to any great extent. See attached image.Optically, therefore, the filter is of good workmanship and provides excellent results, I would have preferred, however, a start and end with blocking so as to avoid possible errors. Considering also that K&F produces filters of other type but with magnetic attachment I think it could be an additional plus for this filter.The quality/price ratio is correct according to the performance provided.I enclose additional photos of the packaging and two shots at the sea.

Very clean glass and no scratches or anything like that.The intensity of the ND filter can be continuously adjusted from ND2 to ND400.I took a few test photos with the filter and am absolutely satisfied.The only drawback for which there is a star deduction: At the maximum filter level you have a bluish shimmering X in the photo. This is a bit annoying, but if you turn the intensity down to just below the MAX level, it disappears again.All in all, you can't go wrong with the ND filter from K&F Concept.

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 ...

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.

I therefore do not recommend setting the filter to this level. To get a feel for how well this filter works, I took my camera outside as a large thunderstorm approached and took a few pictures of one of the cloud formations. I chose two images from this set, one where I didn't use the filter and one where I used it at about 1/4 strength. Although the filter reduces light intensity evenly, the color contrast in the filtered image is much more pronounced and obvious. The most common use for this type of filter is to reduce light levels and then shoot a longer exposure for a scene with movement, such as a waterfall. This is a very nice filter and I couldn't be happier with it. It's very easy to use and works really well.
