I always thought that an inexpensive filter set was sufficient. After this filter, my opinion completely changed. The quality of the filter is outstanding. I really didn't think something like this was possible. You can probably tell – I'm totally blown away by this filter... It's top-notch quality and workmanship. The dial is made of metal, and this alone shows how well the workmanship is.

You also have to keep in mind that filters affect photo quality. This isn't the case with the K&F filter! The highlight here is that I don't need dozens of different interchangeable filters, but can always adjust directly to the respective situation. Personally, I'm still missing the larger increments up to 10 stops. However, I'm so enthusiastic about this filter that I'm going to check whether this filter is also available in increments of 6-10 stops. I would definitely buy it, even though I've previously worked with inexpensive filters around €50. Quality has its price, and in this case, it certainly holds true! But you really get a lot for the price.

The filter sits well on the lens, and I'm not worried about losing it. It's very easy to use. The neutral density filter comes in a nice carrying case, so it's very well protected.

Anyone who enjoys photography knows what an ND filter is for. Since my focus is landscape photography, I can't avoid working with them. I ordered this one from K&F for my full-frame camera.

I was simply tired of always filling my backpack with ND filters of varying strengths. That's when the Nano-X Pro came in handy. To use it with multiple lenses, I ordered the 77mm size. I then work with step-up rings so I can also use it with smaller lenses.

Let's just say: The optical quality and the image quality blew me away! The workmanship is excellent and very well done. The lens thread is cut very cleanly.
The filter is adjustable from ND 2 to ND 32. The larger steps (f-stops) are marked on the ring and are easy to read. It can only be turned within the range of 1-5. It can't go any lower or higher. This way, you always know what your setting is thanks to the stop.

The 77 mm ring weighs 93 grams on my kitchen scale. Everything is solid and feels very good. Adjustment is smooth with slight resistance. That's how it should be.

The optical quality is absolutely flawless, and even in difficult lighting conditions, the filter performs excellently. I couldn't detect any chromatic aberration or color gradients to green, magenta, or anywhere else, even when pixel peeping. Even with backlit foliage or fir trees and dew reflections, the filter's quality is unsurpassed. Finally, an ND filter that does justice to my limited lenses and full-frame sensor. The frame thickness with the thread is only 9 mm. Without the thread, it's 0.63 mm. This means that the filter can also be used on wider-angle lenses without vignetting.

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

Conclusion:
K&F Concept has delivered a top-notch filter here. What's the point of investing thousands in lenses if bad filters make your work difficult or lead to poor results? A clear 5 stars+ from me. I hope this helps with your purchasing decision. The price is also worth it, as you save at least four ND filters.

Well built. Fits my Sony camera well. Great price

Neutral density filters are indispensable in photography. They're used all the time, especially in landscape photography. You know those great pictures with flowing water that looks so "fluffy" and soft – for something like that, you need a neutral density filter.

A neutral density filter, or "ND filter" (neutral density filter), absorbs the light, allowing you to use longer exposures. This long exposure and the movement of the water make it look so beautiful.
By shooting with a neutral density filter, the incoming light is darkened, making it easier to photograph in very bright environments.
Conversely, if you use a neutral density filter in bright environments, you can shoot with a wider aperture or longer exposure times.
By shooting with a longer exposure time, you can achieve beautiful effects.
Normally, images are overexposed if you choose a particularly long exposure time.
With a neutral density filter, you can prevent this and photograph with a long exposure time despite plenty of light.
This results in blurred movements and blurred lines.
This allows you to depict bodies of water, clouds, and fast-moving objects in a particularly creative way.

The K&F Concept Nano-X PRO Series ND1000 filter impresses with its outstanding quality; it comes in a stylish case with a magnetic closure and a cleaning cloth.
I took five pictures with it, which I numbered. The difference is clearly visible.
The filter is worth the money; it screws on easily, and even my lens protector still fits.
This filter makes you want more and gets full marks from me!

Just what I was looking for, they don't pixelate or lower the image quality.

this is a must for overly bright shooting locations to capture the fine details.

Works like it should. No complaints!

K&F filters are usually unbeatable in terms of value for money, and this filter is no different. I use it on a Sony 18-105 f/4 and it’s never let me down.

I've broken down my review 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 free of charge as a Vine product tester, but this has no effect on my review. I also only test things that I can usefully use myself and integrate into my everyday life.

Reason for purchase:
I ordered this filter for 2 reasons. The first reason is that if I only want to travel with light luggage, I don't want to bring my entire plug-in filter system with me. The second is that I can use it well in videography, where I usually film according to the 180 degree rule. This means that in order to obtain a cinematic video image with a certain amount of motion blur in the individual frame, you film with a shutter speed of 1/fps x 2, for example, I film at 50fps, so I need an exposure time of 1/100s, which is not possible without an ND filter, especially in the wide angle range when the sun is shining.

First impression:
The packaging looks very classy, but she is also welcome to do that, given the price that is called for the filter. The filter is in an equally pretty and high-quality filter bag, which I have never seen in this form with round filters before. With the tab on the side, you can lift the filter to prevent accidental contact with the glass when removed. 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 is a dream to the touch, heavy (91g) and easy to grip, I also really like the contrasting adjustment aids. These can also be removed if you want to continue using a lens hood. This requires a small microtorx, e.g. from a precision engineering kit. When the filter is adjusted, it is buttery smooth across all stages.

In the test, the filter shows no weaknesses. As a result, I could not detect any color cast and there was no X-Cross effect. The promised effect of up to 5 aperture levels is maintained. Technically perfect and that is the most important aspect of an ND filter.

Suggestions for improvement:
1. The sustainability aspect, as taken up when using cardboard as a picture frame, could also be reflected in the filter bag by avoiding the use of animal products (leather).
2. An 82mm variant would be desirable and recommended, 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 in the largest possible diameter so that you can adapt it to as many lenses as possible in your own fleet using step-down rings. Of course, this also eliminates the option of continuing to use a sun visor.

Conclusion:
Technically perfect filter in the upmarket price segment.

I hope my review was helpful in your decision making

This filter is made of VERY high-quality material, which you can tell from the moment you pick it up. It doesn't create an X effect, as it has a cap at both ends, and there's no color cast. I've tested it on several lenses; on a 16mm lens, it creates a slight amount of vignetting, which can be corrected in post-production. If you zoom in at 18mm, it disappears. A good buy, highly recommended.
