Neutral density filters are an integral part of photography. They are used all the time, especially in landscape photography. You know these great pictures of flowing water that looks so “fluffy” soft — for something like that, for example, you need a neutral density filter.

A neutral density filter, or “ND filter” (neutral density filter), absorbs the light so that you can expose for longer. Because of this long exposure and the movement of the water, it looks so great.
Taking pictures with a neutral density filter darkens the incoming light and allows you to shoot better in very bright environments.
If you use a neutral density filter in bright environments, you can in return shoot with a wider aperture or longer shutter speeds.
You can achieve beautiful effects by taking pictures with a longer exposure time.
Pictures are usually overexposed if you choose a particularly long shutter speed.
With a neutral density filter, you can prevent this and take pictures with a long exposure time despite a lot of light.
As a result, movements become blurred and flow into one another.
For example, you can display water or clouds, as well as fast-moving objects, in a particularly creative way.

The K&F Concept Nano-X PRO series ND1000 filter impresses with excellent quality, it is delivered in a stylish case (magnetic closure). Includes a cleaning cloth.
I shot at the five pictures and numbered them. The difference is obvious.
The filter is worth the money, it is simply screwed on and even my lens protector still fits on it.
This filter makes you want more and gets full points from me!

Anyone who likes photography knows what you use an ND filter for. Since my attention is the landscape photography I can not avoid working with such filters. I ordered this one from K&F for my full frame camera.

I was just tired of filling my backpack with ND filters of different strengths. So the Nano-X Pro came in handy. To use it on several lenses I ordered it in the size 77 mm. I then work with step up rings to be able to use it on smaller lenses.

To say it right away: The optical quality and the quality of the images has flashed me! The workmanship is excellent and very successful. The lens thread is top clean cut.
The filter is adjustable from ND 2 to ND 32. The larger steps (f stops) are marked on the ring and easy to read. It can also only be turned in this range of 1-5. Below or above it does not work. So you always know by the stop what you have set.

The 77 mm. Ring brings 93 gr. on my kitchen scales. Everything is solid and feels very good. The setting runs well with slight resistance. So it should be.

The optical quality is absolutely flawless and even in difficult lighting conditions the filter delivers top. Chromatic aberration or color gradients into the green, magenta or anywhere else I have not been able to determine even when pixel peeping. Even with foliage or firs in backlight and with reflections from dew, the quality of the filter is unsurpassed. Finally a ND filter that does justice to my limited lenses and the full-frame sensor. The frame thickness with thread is only 9 mm. Without thread 0.63 mm. So you can use the filter on wide angle lenses without edge shading.

Thanks to the two screwed brass handles and the ribbing of the ring, the filter can be adjusted very sensitively.

Conclusion:
K&F Concept has delivered a top filter here. What good is it if you put thousands into lenses but then bad filters make the work difficult or lead to lousy results? From me clear 5 stars+. I hope this is useful for your purchase decision. Also the price is relative because you save at least 4 ND filters.

I was always of the opinion that a cheap filter set was sufficient. After this filter, my opinion has completely changed. The quality of the filter is excellent. I really didn't think that was possible. You might notice - I'm totally flashed by this filter... It is excellent quality and workmanship. The controller is made of metal and here alone you can tell how good the processing is.

You also have to remember that the photo quality is affected by filters. This is not the case with the K&F filter! The highlight here is that I don't need tens of different replacement filters, but can always adjust them directly to the respective situation. Personally, I still lack the stronger gradations of up to 10 apertures. However, I'm really so excited about this filter that I'll see if this filter is still available in 6-10 f-stops. I would definitely buy myself, even though I've worked with cheap filters around 50 EUR so far. Quality comes at a price and in this case it's true! But you really get something on offer here for its price.

By the way, the filter sits well on the lens and I'm not afraid that I would lose it. It is very easy to use. The neutral density filter comes in a nice bag and is therefore very well protected.

already have a few filters at home, including the K&F Concept Nano-X ND Filter 77mm Variable Gray Filter ND2-32 for 75 euros, which I use on my wide angle, for example in bright sunshine (for shooting with an open aperture) and for Long exposures and that's really good. Now I was allowed to test the variable ND filter from the PRO series from K&F, a filter for a whopping 280 euros. Anyone who already works with filters should of course also use high-quality glass on a high-quality lens, but a filter for just under 280 euros is not a pittance and this investment should be well considered. What I can say in any case: The filter is not only great in terms of price but also in terms of performance and processing. It starts with the presentation (packaging) of this filter, neatly finished bag with magnetic cover, suede applications, soft and lint-free lining on the inside, a side strap with which the filter can be transported by pulling it upwards. The filter itself is very well made and easy to use with the two brass tabs. It has a very nice resistance when adjusting, not too heavy and not too light. The glass shows no defects and the threads are cut absolutely clean. I can only say about the image quality/image performance: TOP! There are no color errors / color casts or anything else negative. So I can work with my lens in bright sunshine even with an open aperture and, if I like, also realize long-term exposures with a slightly closed aperture with the help of the filter. As I said, image quality is as good as if I had no filter on the lens at all and that's how it should be. The pictures I uploaded (modest test shots) were taken wide open and against the sun. My conclusion about this filter: Very high-quality processing / image quality impeccable / feel excellent. Price very high Now everyone has to decide for themselves whether such an investment is worth considering.

I've used K&F ND filters in the past, so I wasn't surprised at the quality compared to newbies. The filters enable sharp focusing without restrictions. Thanks to the really extremely thin glass and frame, there is no clouding or dark spots around the edges. It is ideal that the filter has a thread on the front, so that you can easily mount several in a row. The frame has small brackets so that you don't have your fingers in the picture when readjusting. The ND Filter 67mm Set is rounded off by a beautiful leather storage case. Overall absolutely great!

occasionally carried a few individual filters with me. But it was often too expensive for me to fiddle around with it in nature. Screwing the filters together to get further addition levels is also fiddly. There are enough individual ND filters, but every time you had to change the filter again... With this filter here you basically trick the entire handling process. I hadn't even found out such a thing existed. So I included a little video so you can see the function. Even if there is "only" ND2-32 here, you can still see what these products can do. Especially for experimentation, a matter of seconds, sometimes with a different filter setting. With low filter strengths, the camera automatic is sufficient and you can see the current shutter speed when setting the filter. Soft water structures with relatively bright light or soft clouds in the sky etc. pp. I didn't really notice scattered lights or reflections, but I edit something like that on the PC anyway. The price of this product is high, but considering that it covers multiple filters at once, it's not too bad. However, the general question is what kind of filters do you really need. I previously had an ND8 and an ND1000. Sometimes an ND 4000 would have been required (to safely create 'abandoned' objects/rooms). However, I find the concept here really innovative and practical.
