First of all, I was pretty impressed with the packaging this filter came in.

It’s good to see that at this price point, exceptional-quality packaging is used to protect this gear which is relatively expensive for what it is. It’s just a piece of glass right? Well, actually no. I found that it functions best, at least in my application, for reducing glare of windows, windshields, water, and basically anything that has a reflection.

I can shoot video on a car and eliminate the distracting elements of trees passing by, or just the environment in which the car is in.

This is truly a beautiful piece of glass, and you don’t have to worry about it “downgrading” your footage or photos. It’s definitely more of an upgrade.

Aunque tengo un filtro de esta misma marca que hace su función correctamente, no permite modificar la luz y el contraste. Este filtro sí lo permite, aunque sutilmente, permite girar suavemente la lente una vez acoplado y modificar en luz, contraste y color la percepción de la imagen. No es un cambio con mucha variación, pero permite retocar levemente la intensidad con que se capta una imagen.
Se le podía poner un punto negativo por el precio, pero, en mi opinión, es una valoración personal y relativa.
La calidad es muy buena y cumple perfectamente su cometido.

wasn't actually a big fan of filters, but it always had to be a POL filter. As an ignorant photographer, you get it drummed into you again and again: get a polarizing filter, you need it, because you can never get the effects of it in post-processing. So I started with cheap polarizing filters and quickly stopped. I currently have a pole filter from Rodenstock, with which I am actually very satisfied, apart from the fact that it is sometimes a bit bitchy when screwing it on and off. So far I only knew K&F in the cheaper filter line and was therefore looking forward to a comparison with my Rodenstock. The polarizing filter makes a great impression right out of the box and gave me a "wow" effect. The frame is made of brass metal and feels extremely good and high quality. The screw thread is manufactured with absolute precision and the filter itself has a strong, high-quality coating. What I then noticed when using it: how easily it can be screwed onto the lens and unscrewed again. In fact, I've never had that with any other filter. No snagging, no jerking, nothing. It doesn't degrade my photos in any way. No ghosting, no flares, no color cast. Absolutely great. All in all, I am extremely surprised by the high quality of this filter and will therefore continue to keep an eye on K&F when it comes to other filters. I am extremely satisfied and can therefore recommend it without hesitation, despite the higher price.

The CPL filter from K&F comes in such an attractive packaging that you can immediately conclude that you have something really high-quality in your hand. In the box you will find a noble-looking case with a magnetic closure, which protects the filter very well. This CPL filter is "slim", which has the small disadvantage that you can't hold it a little harder when turning. Which brings us to the only small point of criticism on my part. Otherwise you get a very high-quality CPL filter here, which fulfills its purpose brilliantly, namely to reduce or prevent reflections, which makes the photos appear richer in contrast and more interesting in color as soon as they are taken. In post-processing, there are limits in this respect, and quite apart from that, I very often save myself post-processing because the photos simply come out of the camera in a more harmonious way and without looking artificial. The quality is impeccable, the filter itself is of very high quality. The image quality is perfect, no color fringes or distortions. For that 5 stars. A filter that I absolutely recommend!

Viene fornito un filtro di polarizzazione da 82 mm del marchio K&F Concept della serie Nano-X PRO. Nel complesso, trovo la presentazione molto preziosa, accattivante e va per me nell'area PRO - anche il prezzo ;-). L'unboxing è stata un'esperienza WOW! Un filtro che ti fa sorridere quando lo disimballi deve essere buono - ..e lo è. Penso che il filtro sia davvero fantastico! È ben fatto, fa un'impressione di alta qualità, può essere facilmente avvitato sul Tamron 24-70mm 2.8f G2, la resa dell'immagine è ottima e non vedo macchie scure, "ghosting" o simili ai bordi (come con altri produttori / prodotti più economici). I riflessi possono già essere eliminati quando si scattano foto, il che a sua volta riduce la noiosa post-elaborazione. A questo punto ho lasciato il test antigraffio, dopotutto voglio usare il buon vetro con le massime prestazioni ;) Non ho bisogno di un graffio su di esso per il momento, verrà inevitabilmente da solo ad un certo punto. un problema: l'imballaggio, cioè la scatola di trasporto, non è mio al 100 % - perché? Perché sono più un tipo dal guscio duro, dove posso mettere il filtro. Ben strutturato in sé, ma non altrettanto pratico per me personalmente. Conclusione: per me il filtro polarizzatore è un'ottima scelta. Certamente non un dentice a prima vista, ma ottieni anche un prodotto di alta qualità a un prezzo del genere. Ho già menzionato la debolezza con il caso di cui sopra. Non è proprio il mio genere, ma alla fine è anche una questione di gusti. Alla fine quello che conta è la qualità del filtro polarizzatore, ed è ottimo!

The K&F Concept 77mm Circular Polarizers Filter Super Slim with 36 Multi-Layer Coatings, High Definition Circular Polarizing Filter (CPL) Camera Lens Filter (Nano-X PRO Series):

Is one of the finest quality filters I've used. Everything about this is premium. From the packaging to the filter wallet to the product itself is top notch. It has a brass powder-coated frame and high quality, crystal clear optics. A filter I don't feel too bad putting in front of my best glass. The threads are precisely machined and screw in and out very smoothly. The CP rotation feels impossibly, buttery smooth. Like its hydraulic but it's not, it's just a ridiculously smooth action. Like a high quality potentiometer. The knurling feels very nice, and over all the whole thing feels really great in the hand. As far as the polarization effect it works as it should and as expected, and with crystal clear optics. The included filter wallet is made from suede and heavy denim, with a pull ribbon to retrieve the filter with out stick your fingers down the pouch. The whole thing is rather lux. The packaging itself is a very classy, thick black box, with gold accents. the box also turns into a picture frame. The package also contains a microfiber cloth. Overall this is a very deluxe filter. It is a bit pricey, however the quality meets the price for sure. You get what you pay for sometimes and this is one of those times. You don't want to buy top quality lenses, costing thousands of dollars, and put a cheap filter on it. This is the type of filter you can feel good using on your best lenses. Precision machining and great quality glass.

K&F has always been known as a company that produces fairly inexpensive gear that performs "good enough" for most non-professional situations. With this filter, it appears K&F is going after the professional shooters.

The optical quality of this filter is fantastic. I had zero glaring issues when using this outside which is something I usually run into with budget filters. There was very little color cast even when using at the higher strengths. It comes with just a fantastic high quality case.

I hope to see more filters like this from K&F. I am a big fan of really high quality gear which it seems K&F is starting to produce now.

Filter is nice and I would recommend this product

I shoot professional gear and don't mind paying for products that produce first class results, are durable, and are simple to use. This filter meets my criteria for a professional quality photography product.

The optics are high quality. I don't see any aberrations in the resulting images. Mechanically, the movement of the filter is very smooth. We'll see how it does with some weather and grit, but I expect it will continue to operate well. I put this up against the very best I have used and never look back. This company has produced an excellent, professional quality filter.

I really love the uses for portraits and remove reflected from skin, especially darker Melanated skin. I keep Polaroid and Kate in my bag at all times and it’s polarizing filter easily. The best one I ever got doesn’t stick like other ones in my kit sometimes they stick to my lenses not have a hard time removing it. This one is very easy to remove, and the focusing or rendering of the polarizing filter is Very smooth.
