52mm Variable ND Filter ND3-ND1000(1.5-10 Stops) Ultra-thin HD with Double-sided 28-layer Nano-coating Nano-Xcel Series

Highly versatile filter with exceptional clarity and durability. A must-have for photographers and videographers seeking precise exposure control.

My equipment: Canon 90D 18-135mm 3.5/5.6 USM lens

I really love this cover. I have never had an ND filter before, but I am completely blown away by the features of this one. As you can see from the photos I've uploaded, they work wonders in filtering out some of the harsh light from day shooting, they also let me capture a pretty awesome sunrise! I have not used them for motion photos, yet, as I typically do landscape photography, but they do help with pictures during the day to avoid having overly exposed areas in your pictures. The case it comes with is also top tier, made with nice leather and easy to remove from the package when you're looking to use it. I have not noticed any white balance issues with it, but I take all my photos in RAW format, so I don't usually pay much attention to my white balance (I fix that in the editing process). The lens itself is great quality, as well. It adjusts very easily and tethers nicely to my lens. I cannot speak highly enough about this filter, if you are shopping for something to bump your photography to the next level, this is an excellent place to start!

Out of the gate the first thing you’ll notice is the build quality on this filter. It it feels really solid in your hand, there are no loose parts and has a good weight to it. I like how it has little grip extenders that you can grab a hold of to turn the filter. As the filter does need a little bit of pressure to turn it, it’s nice to have these so your fingers don’t slip. I like how it has hard stops on the ND filter so you don’t accidentally turn it too far, which can mess up your image really quick regardless of what brand filter you’re using.

I have never really liked VND filters. I usually prefer fixed NDs. This K&F VND has changed my mind. It has exceptionally build quality. It is completely clear throughout its turning range. K&F also include a very nice case. Overall its fantastic.

K&F Concept filters are always of very high quality. I haven't had a neutral density filter yet. That's why I'm happy to be able to test it.

Even the packaging is of very high quality and the included leather case is very nice and sturdy. The filter can be easily pulled out through the band. The flap of the bag is magnetic.

Thanks to the small orange handle, the filter is infinitely easy to adjust. The effect is astounding. It helps to adjust the exposure comfortably in a wide variety of lighting situations. I mainly use it in lighting situations where I want to shoot with an open aperture and daylight is too strong for that. The colors in the image are not negatively affected by the filter.

Great filter for a decent price. 5 stars from me.

I ordered this K&F Nano X-series Variable ND Filter ND3-ND1000 (52mm) for my “always-on lens”.
The filter arrives at home in a very elegant packaging, including a leather case.
I tested the filter on my 28/2.8, it could be screwed on without any problems, and the adjustment of the strength also works brilliantly due to the very pleasant resistance and the integrated nose. The filter produces neither color casts nor image errors. For me, the ND3-ND1000 is a perfect companion for open-aperture photography in daylight/sunshine to long exposures, so it can be used very flexibly for me.
I can definitely recommend this filter because of its very good quality (processing/image quality).

ND filters are essential if you're going to be shooting with anything that may involve bright outdoors. For example, you can use an ND filters indoors to lower the exposure of an outdoor window, and then you can add lights to bring the exposure back up of your subject, that way both are perfectly exposed.

K&F Concept made the interesting design choice to add a putter, and I'm all for it. It makes the function of changing the ND value a lot easier to do than the traditional way, mostly because sometimes I've tried to rotate a part of the filter but it wasn't the part that actually controlled the ND value.

Overall, I really recommend this filter. It's fantastic!

Wer gerne fotografiert weiß, für was man einen ND-Filter benutzt. Da mein Augenmerk die Landschaft Fotografie ist komme ich nicht umhin mit solchen Filtern zu Arbeiten. Ich habe mir diesen von K&F für meine Vollformatkamera bestellt.

Ich hatte es einfach satt immer den Rucksack mit verschieden starken ND-Filtern zu füllen. Da kam mir der Nano-X gerade recht. Ich ihn mir in der Größe 52 mm. bestellt. Ich arbeite dann mit Step up Ringen, um ihn auch an kleineren Objektiven nutzen zu können.

Um es gleich zu sagen: Die Optische Güte und die Qualität der Abbildungen hat mich überzeugt! Die Verarbeitung ist hervorragend und sehr gelungen. Das Objektivgewinde ist top sauber geschnitten.
Der Filter ist von ND 3 bis ND 1000 verstellbar. Die größeren Schritte (f-Stopps) sind auf dem Ring markiert und gut abzulesen. So weiß man, was man eingestellt hat.

Der 52 mm. Filter bringt 28 gr. auf meine Küchenwaage. Alles ist massiv und fühlt sich sehr gut an. Die Einstellung läuft gut mit leichtem widerstand. So soll es sein.

Die optische Qualität ist absolut fehlerfrei und selbst bei schwierigen Lichtbedingungen liefert der Filter Top ab. Chromatische Aberration oder Farbverläufe ins Grüne, Magenta oder sonst wohin habe ich auch beim Pixelpeeping nicht feststellen können. Auch bei Laub oder Tannen im Gegenlicht und mit Reflektionen vom Tau ist die Güte des Filters unübertroffen. Endlich ein ND-Filter der meinen Limited Objektiven und den Vollformat Sensor gerecht wird. Die Rahmendicke mit Gewinde beträgt lediglich 10 mm. Ohne Gewinde 0,75 mm. Somit kann ich den Filter auch auf weitwinkligeren Objektiven ohne Randabschattungen verwenden.

Dank des geschraubten Griffes und der Riffelung des Ringes lässt sich der Filter sehr feinfühlig einstellen.

Fazit:
K&F Concept hat einen Top Filter abgeliefert. Was nützt es, wenn man Tausende in Objektive steckt aber dann schlechte Filter die Arbeit schwer machen oder zu miesen Resultaten führen? Von mir klare 5 Sterne. Ich hoffe das ist nützlich für Eure Kaufentscheidung. Auch der Preis relativiert sich da man sich mindestens 4 ND-Filter spart.

Verpackung und Versand

The package with the K&F Concept Nano X series variable ND filter ND3-ND1000 neutral density filter 67mm (1.5-10 aperture steps) was delivered quickly and securely packaged.
I love photography and was happy to be able to test this filter.
The black outer box with the filter was once again coated with a plastic film so that no moisture could penetrate. The filter itself is in a high-quality plastic case. The flap of the bag is magnetic. So no unnecessary flipping around to get to the filter. Very practical: The filter can be easily removed with a strap. The whole thing looks really elegant and is also a great gift for a hobby photographer.

The filter itself is made of Japanese optical glass with 28-layer nano-coating on both sides, which should prevent a certain lens reflection and, of course, glare caused by various types of lens. light sources. According to the manufacturer, the ND filter is waterproof, oil and dustproof, which benefits the requirements of nature and hiking in particular. I have the feeling that the filter is very robust. It weighs 45 g with a lens size of 67 mm. Of course, the price is appropriate accordingly.
The filter frame is made of aircraft aluminum, has an ultra-wide angle construction and is just 7.4 mm thick. Anyone who, like me, has always used a few different dark gray filters will appreciate this fact of only using 1 filter.
I use neutral density filters in particular when taking pictures of water at a lake or of running water or waterfalls. Even when taking long-term photos of places that you would like to photograph without people, this part is fantastic.
The function of this adjustable filter is quite simple. Press the practical slider and the filter becomes darker or lighter again as needed (see photos) So you can easily try out different settings and effects without having to constantly change the filters.
However, I also have to mention that you cannot attach the sun visor to this filter because the slider is of course in the way. It's a bit impractical, but okay, you can't have everything...
Conclusion: With this type of aperture adjustment, the price is within the normal range. There are certainly cheaper ones, but the K&F filter is built to a higher quality. The results are certainly impressive. Since I'm not a professional but simply enjoy taking pictures, this filter is actually a great companion for me and I can recommend it with a clear conscience.

As a product tester, I work very intensively on each product tested, put it through its paces, so to speak, and only give reviews that I can fully stand behind. I hope my review was useful to you.
