Anyone who enjoys photography knows what to use an ND filter for. Since my focus is on landscape photography, I can't avoid working with such filters. I ordered this from K&F for my full frame camera. I just got tired of stuffing my backpack with ND filters of different strengths. That's where the Nano-X Pro came in. In order to use it on several lenses I ordered it in the size 77 mm. I then work with step rings to be able to use it on smaller lenses. To say it straight away: the optical quality and the quality of the pictures flashed me! The processing is excellent and very successful. The lens thread is cut very cleanly. The filter can be adjusted from ND 2 to ND 32. The larger levels (apertures) are marked on the ring and are easy to read. It can also only be rotated in this range from 1-5. It doesn't go below or above. So you always know what you have set at the stop. The 77mm. Ring brings 93 gr. on my kitchen scale. Everything is solid and feels very good. The adjustment goes well with slight resistance. It should be so. The optical quality is absolutely flawless and the filter delivers top quality even in difficult lighting conditions. I could not determine any chromatic aberrations or color gradients into green, magenta or anywhere else during pixel peeping. The quality of the filter is unsurpassed, even with backlit foliage or fir trees and reflections from dew. Finally an ND filter that does justice to my limited lenses and full frame sensor. The frame thickness with thread is only 9 mm. Without thread 0.63 mm. So you can also use the filter on wide-angle lenses without edge shadowing. 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's the point if you put thousands in lenses and then bad filters make the job difficult or give lousy results? Clear 5 stars+ from me. I hope this is helpful in your purchase decision. The price is also relative because you save at least 4 ND filters.

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!

have broken down my evaluation for you and them into reason for purchase, first impression, product test, suggestions for improvement, tips and conclusion. I hope this helps with clarity. I received the product for free as a Vine product tester, but this does not affect my rating. I only test things that I can use sensibly and integrate into my everyday life. Reason for purchase: I ordered this filter for 2 reasons. The first reason is that if I just want to travel light, I don't want to take my complete cartridge filter system with me. Secondly, I can use it well in videography, where I usually film according to the 180 degree rule. This means that in order to get a cinematic video image with a certain degree of motion blur in the individual image, you film e.g. B. with a shutter speed of 1/fps x 2, I'm filming at 50fps, so I need an exposure time of 1/100s, which is not possible without an ND filter, especially at wide angle in sunshine. First impression: the packaging looks very classy, but given the asking price for the filter, it is allowed to do so. The filter is in an equally pretty and high-quality filter bag, which I have never seen in this form with round filters. The tab on the side allows you to lift the filter to avoid accidental contact with the glass when removing it. The closure of the bag is magnetic. A nice gimmick is that the cardboard packaging of the filter can be transformed into a small picture frame. Product test: The filter feels like a dream, heavy (91g) and easy to grip, I also really like the color-contrasting adjustment aids. These can also be removed if you wish to continue using a lens hood. For this you need a small Microtorx, eg from a precision mechanical kit. When the filter is set, it runs buttery smooth across all stages. The filter showed no weaknesses in the test. As a result, I could not detect any color cast and there was also no X-Cross effect. The promised effect of up to 5 f-stops is retained. Technically perfect and that is the most important aspect of an ND filter. Suggestions for improvement: 1. The sustainability aspect, as taken up when cardboard is used as a picture frame, could also be reflected in the filter bag by not using animal products (leather). 2. An 82mm variant would be desirable and recommendable, then the filter could also be used on (m) a 24-70mm/2.8, for example. Tips: It is always advisable to buy such a filter with the largest possible diameter so that you can adapt it to as many lenses in your own fleet as possible using step-down rings. Of course, this also eliminates the possibility of continuing to use a sun visor. Conclusion: Technically flawless filter in the upper price segment. I hope my review was helpful in your decision making.

My buddy and I have been running a channel on Youtube for several years and have also become partially self-employed through it. We produce content for companies and we have now put together a lot of equipment for this purpose. When it comes to ND filters, we have been in the cheap segment so far and have relied on fixed filters, as we haven't heard anything good about the cheap variable filters.

We now use square filters with matte boxes for larger productions. But especially for smaller orders, where we need a lot of flexibility, we rely 100% on the Nano-X Pro. This covers exactly the area that we need. The optical quality of the images is really great and there is simply no falsification. In some cases, we also use an adapter for square filters after the Pro ND. This works because the Nano-X Pro has a thread into which you can screw additional filters.

In theory, it is even possible to use it in conjunction with a matte box and a rectangular filter. The options are very varied.

I can only say words of admiration about the workmanship, simply terrific. As soon as I unpack it, I have the feeling that I am holding a super high-quality product in my hands. The workmanship is impeccable and the case makes an equally high-quality impression. The adjustment of the filter is very smooth and the filter has not even tilted so far.

I can make my recommendation without hesitation. Anyone who makes the, admittedly quite large, investment will be rewarded with quality and visual material, which definitely justifies the price. Anyone who claims that a cheap filter does the same in this regard has not yet addressed this issue in detail.

was always of the opinion that a cheap filter set was sufficient. After this filter, my opinion completely changed. The quality of the filter is excellent. I really didn't think that was possible, totally flashed by this filter... Quality and workmanship is excellent. The controller is made of metal and here alone you can tell how good the workmanship is. You also have to keep in mind that photo quality is affected by filters. This is not the case with the K&F filter! The highlight is that I don't need umpteen different replacement filters, but can always adapt them directly to the respective situation. Personally, I still miss the stronger gradations of up to 10 apertures. However, I am really so enthusiastic about this filter that I will see if this filter is still available in 6-10 f-stops. I would definitely buy one, even if I've worked with cheap filters around 50 EUR so far. Quality has its price and in this case it is true! But for the price you really get something here. By the way, the filter fits well on the lens and I'm not afraid of losing it. It's very easy to use. The gray 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.

Neutral density filters have become indispensable in photography. Especially in landscape photography they are constantly used. You know those great pictures of flowing water that look so "fluffy" soft - for something like that you need a neutral density filter, for example. A neutral density filter or "ND filter" (neutral density filter) absorbs the light, allowing you to expose longer. It looks so amazing because of that long exposure and the movement of the water. Taking pictures with a neutral density filter obscures the incoming light and allows you to shoot better in very bright environments. In turn, using a ND filter in bright environments allows you to shoot with a larger aperture or slower shutter speeds. You can achieve beautiful effects by taking pictures with a longer exposure time. Images tend to be overexposed when you use a particularly slow shutter speed. With a gray filter you can prevent this and take pictures with a long exposure time despite a lot of light. As a result, movements blur 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 its excellent quality, it is delivered in a stylish case (magnetic closure). Including cleaning cloth. I shot 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 protection still fits on it. This filter makes you want more and gets full marks from me!

I've used ND filters from K&F in the past, so I wasn't surprised by the quality compared to newbies.

The filters allow sharp focus without any restrictions. Thanks to the really extremely thin glass and the thin frame, there is no cloudiness or dark spots at the edges. It is ideal that the filter has a thread mounted on the front, so that you can easily mount several of them one behind the other.

The frame has small brackets so that if you want to readjust it, you don't have fingers in the picture.

The ND Filter 67mm set is rounded off by a nice leather storage pouch. Overall, absolutely great!

The K & F Concept filter arrives here safely packaged. It comes with a duster and a bag for storage.

The workmanship of the filter is really first-class. High-quality materials, excellent handling, a perfect fit and not too heavy on the lens or in the hand.

The filter is simply attached to the lens using a rotating mechanism.

The filter conjures up wonderful images that you no longer have to rework.

The price is certainly a deterrent for now - but in my opinion, you get one of the best filters on the market here. Professionals MUST strike, amateur photographers CAN strike without hesitation
