I bought the filters to add to my collection. I have now found the right ones. They were delivered very quickly and were delivered in a very elegant packaging with a magnetic closure. The filter itself was packed in a high-quality plastic case. With the help of 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.

I use the filter both for filming with the DSLR, as well as for long-term exposure during the day with an open aperture, especially when filming, it is simply beautiful with an open aperture. The ring is easy to turn. However, sound should be recorded externally, because the ring clicks quietly in the intended positions. The packaging is ideal for transport and also withstands the attacks of my 1-year-old daughter. The picture quality looks great. In any case, I could not see any color casts or other disturbances. I am very satisfied with the ND filter.

I've tested the filter for a few days now and I have to say that I really like the option to adjust the ND level. With my old camera I had different filters, which of course is always a question of space if you just want to get going. Of course, the results are not comparable to much more expensive ND filters. But it's just practical for taking nice pictures of bodies of water, or to put waterfalls in the right picture. What I have noticed negatively so far is that there was a reflection within the filter in direct sunlight, but this could be eliminated by a slightly different position of the camera. I will continue to test the filter. The durability must be observed to see if there are any problems with the rotating mechanism in the long run.

An ND filter that keeps what it promises. As soon as you unpack it, you notice that great value was placed on high quality. The transport cover is already very neatly worked and thus ensures safe transport of the filter. The filter itself works really well. As soon as you unscrew it, you can tell that everything feels really good. The metal ring is slightly matted, which ensures a great grip, especially when adjusting. Adjusting between ND 2-32 works seamlessly and really smooth. Absolutely jerk-free but also heavy enough that nothing changes so quickly. When setting it up yourself, you don't notice any disruptive influences such as the typical cross, which was often the case with variable ND filters. Also, the value from ND 2 to ND 32 is perfect for most long exposures. Especially when it comes to sunsets or the typical smoothing of water, this ND filter is perfect. In addition, the filter is nano-coated so that water droplets roll off directly and the filter cannot fog up in the first place. What was also important to me was that the filter is not so thick and heavy. This is where the K&F Concept ND Filter really shines. It is almost as thin and narrow as a normal UV filter. A feature that I like very much. Since the filter starts at ND-2, you wouldn't have to write it off even with normal photos and can vary very quickly. After my first tests, I have to say that I wouldn't want to be without this filter in my camera bag anymore.

I ordered this filter for my Canon 800d and it works like a charm. The packaging it came in gives you a sense of the premium build quality of the product. As it is a variable Nd filter I can leave it on my lens as there is no need to remove the filter to get more light. I had high expectations for this filter while ordering and its results are better than my expectations. The filter ring is very smooth and does not stutter when recording a video. There were no dark spots on the sides in my photos which I have experienced for some other filters. Delivery by Prime was very fast and the product arrived safely in one day. I would definitely try other products from K&F Concept,

The filter comes in a very elegant packaging with a magnetic closure and also has a small plastic box for transport. The filter can be easily screwed on and off the lens , estimated at the maximum setting 3-4 full f-stops. You can see the effect best in backlight or strong contrasts in the subject, I'm looking forward to testing the filter in the midday sun in summer.

Bought and used on my trip to Hawaii. Good quality, no issues, super clear photos using it on my tripod.

Great filter . Using this on my Zeiss 16-35 f/4 on a Sony a6500 for film use. The picture and build quality of the filter is good value for money , made with quality glass . My only complaint and this is pretty big deal for me is my lens hood will not fit while using this filter . It’s one or the other for me now , which is a bummer.

Exactly what I was looking for. I'm often on the road during the day and like to take long exposures. But since the camera settings are not enough, I looked for a filter. I've had great results so far.

So that you can form your own opinion, I have uploaded the pictures here without any editing. After post-processing, the pictures are really world class... There are no wrong colors at all. It can also be used in the wilderness when panning for gold. A tripod is highly recommended.
