K&F CONCEPT 82mm Variable ND2-400 Lens Filter (1-9 Stops) for Camera Lens

As an intermediate photographer thats most of the time on a budget Ive found this company to have some good quality stuff for a fraction of the price most big name brands sell them for. Ive so far oreded a few items from K&F CONCEPT and I got to say their product is really good so far. The lens filter is just as described and I love the matt finish of the material used. The material used feels high quality and feels really durable all for a good reasonable price! Its not too heavy very light weight and was able to install on to my lens with no issues. Now there is plenty more positive things to say but, I just have a couple of things that I found personly disappointing/annoying when using the lens filter. Cons: 1. The lense filter sits properly but you loose the ability to use your lens cap. Id have to remove the filter and place lens cap where as other filters I was able to keep on my lens and still place the cap on. 2. The dial to choose how much of the ND filters to use just continues to spin I feel like when shooting having to continuously look where im setting it too will become tedious. Id suggest having stoppers when reached max or min and to possibly have groves to feel what setting im on like slight click in between each "setting". But thats just me being annoying and picky lol. Aside from the "negative" opinions I will be buying more products from this brand. As it is I am currently waiting on a lense cap with UV filter for one of my other lens and I cant wait to receive it.

This is the coolest filter I have ever purchased for a camera. Okay, so it's not magic, but to be honest it might as well be. I have no clue how it works but it is the smoothest transition from each level. It goes from barely there to extremely dark in a smooth transition just by slowly turning the dial. Way cool, practical and perfect! Image quality through it is great. Don't hesitate to buy this. Also, fyi, you can buy a OEM cap to fit it. The listing has the lens cap size in the description so I ordered a lumix cap in that size and it fits perfectly. You will want one so you can leave the filter on without issue. Also, a word of CAUTION!! Don't put this on with an auto close cap!!! It jacked my camera up and I was afraid it was gonna be wrecked. Took some finagling but I finally got the filter off and restarted camera and it fixed the error. But it was scary!! So be sure to have the auto cap removed before using! These filters do not work with an auto cap!

Used it once on the golf course. A lot of my photos came out blurrier than I expected. It was on a golf course, and shooting at 1/1000, so I understand some of the action shots could be blurry. But some of the pictures where they were just standing or walking slowly were also blurry. I couldn't increase my shutter speed too much more, as the preview was coming up really dark, even with the filter all the way on Minimum. In retrospect, I could have just increased shutter speed and not used the filter. Maybe for video, but don't think it was needed for photo. By the way, this one is not compatible with the magnetic ring.

This ND filter is a fantastic addition to my photography gear! Made from high-quality AGC optical glass with 8 multi-layer coatings, it really reduces reflections and glare, resulting in crystal-clear images. The 1-9 stop light adjustment is incredibly versatile, perfect for everything from bright daylight shots to more controlled, low-light scenes. The 360-degree rotation offers precise control over the light reduction, although, at the highest stops, I did notice a faint cross-pattern ("X" effect), which is typical for adjustable ND filters on some lenses. The filter itself is sleek and slim, just 7.4mm thick, and the CNC-patterned edge provides great grip, making it super easy to attach or adjust quickly. I love the anti-glare finish, which minimizes stray reflections, especially in challenging lighting. One thing to note: you’ll need a 55mm lens cap for this 52mm filter, but that’s easy to work around. Overall, it’s an impressive ND filter with outstanding performance and durability. Highly recommend it to anyone looking to improve their outdoor and landscape photography!

I've been very impressed with this item for the past 2ish years. It's been a durable design at a very affordable price. It fulfills everything that it said it would and is easy to install and use. My images are still very clear and not cloudy as I use the filter. It makes a huge difference in my image using this filter to help reduce the harsh light coming into my camera. There is a slight vignette on the image, but not drastically noticeable. The only downside is the lack of gauges to keep track of what stop the filter is at. It requires you to watch the LCD screen as you turn the knob on the filter. Still happy with the product, but wish there were numbers on the filter. Overall, highly recommend, especially for the price!

Was a gift for a friend

Pretty amazing for the price. Love it. Very precise threads, threaded easily to my RF 24-70. True Min and Max are somewhere around the words Min/Max not the dot markers. Totally fine with me. K&F is slaying it, not my first purchase from them.

This thing started off giving great quality. I think the problem is that it doesn't have a stopping point when turning the ring to pick the stop number. In assuming that after turning a few times the glass somehow becomes misaligned and drops the quality. I've been able to really use it for the first time yesterday and it destroyed many pictures because of the quality. When it works well I will say it's a 5 star. But I have to rotate the ring multiple times and take a picture after each rotation before I find a good enough quality to keep. It takes away from the experience so I just took it off and fixed the brightness of my images in photoshop. So I'm giving a 3 start simply because if you find the sweet spot then you have hit gold for the price but I do wish I picked a better one. I must add that this is my first time using a ND filter so it could be something I'm doing wrong but it seems like it should be straight forward to use.

It has got just about all your required settings. Ultimate & Optimum useful filter.

I ordered the 52mm filter because the 30mm f1.4 sigma lens for sony e-mount cameras has a 52mm thread but after lens arrived, I couldn't fit it on. But after-service support was pretty helpful in telling me this

Ottimo filtro a ND variabile io l'ho montato su un obiettivo Sigma per Lumix e per le interviste è perfetto non distorte assolutamente l'immagine

初めて使うのには良い商品かも。 場所に合わせて調整出来るのも良いですね。 もっと早く買っとけば良かった。調整が簡単なのが良いです。

Ich war schon seit längerer Zeit auf der Suche nach einem eher günstigen ND-Filter für den seltenen Gebrauch. Natürlich findet man so einiges auf Amazon, allerdings hat immer irgendetwas nicht ganz gestimmt. Entweder er war nicht Variabel einstellbar oder man hätte noch einen eigenen Filterhalter benötigt (die rechteckigen Filter),... Es gab einige Gründe warum ich nichts passendes gefunden hatte. Dann eines Tages, bin ich auf den K&F Concept gestoßen. Ich hab mir gedacht "Naja, für um die €20,- wird man schon nicht viel falsch machen können.. Und wie ich recht behalten sollte! Nach einem gewohnt Blitzschnellen Versand, dank Amazon Prime lag das Ding also in meinem Postfach. Ausgepackt und geöffnet, war ich schon einmal davon überrascht, dass neben dem Filter, der in einem eigenen, mit Moosgummi gepolstertem, Hardcase daher kommt, auch noch ein Mikrofasertuch dabei war. Für 20 Euro beachtlich. Abgesehen von oben gennanten war auch noch ein kleiner Zettel dabei, auf dem man Kontaktdaten finden konnte, sollte man nicht zufrieden sein. Der war in Deutsch verfasst und leider von Rechtschreib- und Grammatikfehlern nur so übersät. Da ist mir Englischer Text wie auf der Filter-Box doch lieber. Nun zum Filter. Natürlich darf man sich für einen so günstigen Preis, kein Spitzenlevel erhoffen, aber solange man im auf dem Filter angegebenen Bereich bleibt und sich dem maximalen Grenzwert nicht all zu sehr annähert ist, ist auch die Verdunkelungsqualität echt nicht schlecht. Man sollte sich selbstverständlich im klaren darüber sein, dass sich Objektiv Deckel nicht mehr auf dem Filter befestigen lassen. Zumindest, war das bei meinem der Fall. Alles in allem eine sehr solide Investition für knapp 20 Euro. Ich würde und werde ihn wiederkaufen. Ein kleines Video dazu, werde ich bei Zeiten machen und dann hier verlinken.
