As soon as you unpack it, you notice that this filter is of very high quality, as it comes in high-quality hard cardboard packaging. A very stylish and practical case is also included. The filter itself also looks super high-quality, scratch-resistant and works wonderfully!
It is very easy to screw onto the lens and also rotate it, although this is a bit difficult. But that doesn't mean it slipping either!
The price is quite high, but anyone who is willing to pay that much will have an absolute top product!

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!

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 restrictions. Thanks to the really extremely thin glass and the thin frame, there is no cloudiness or dark spots at the edges.

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

The whole thing is rounded off by a nice leather storage pouch. Overall, absolutely great!

I am a Professional Home and Personal Chef and I also teach cooking both in videos, directly online and in live streams. I am also an online influencer, Vlogger and commentator. As such, my needs are extensive and many when it comes to cameras, microphones, mixers, input devices to computers, studio, lighting & editing equipment, as well as various control apps. I am picky and critical in reviewing and care little about brand names or product claims. If they are good, I will praise and recommend them, and if not, I will fully explain my reasoning for saying so. Honesty is my reviewing policy!

I have become a big fan of K&F and their filters. Even their lower-end filters perform brilliantly, but THIS one takes the cake! It's an absolutely superb filter that I would not hesitate to put against the most expensive high-end German filters than cost more the double the price!

The 36 multi-layer NANO-X coating is very evident in the quality of polarized images it produces. The threads on the filter are micro-fine and screw into a lens without any issues whatsoever. The circular adjustment is smooth as silk and effortless.

For me, this is a very versatile CPL lens at 67mm that many of my Sony, Sigma, and virtually all of my Tamron lenses use! I have tested mounting and removal on every compatible lens with a single issue.

This is the highest quality level of K&F Filters (NANO-X PRO). It comes with a 2-year warranty, and a manual is available online. They add a Microfiber cleaning cloth in a sealed pouch in the box as a nice bonus. Thoughtful!

The filter comes secured in a VERY nice faux leather overlap storage pouch. Clearly well thought-out.
Don't be put off by its Chinese Manufacture! It is super high-end and exceptionally well designed and produced. The company has won a number of INTERNATIONAL awards for design and their patented products are available in 56 countries.

This is truly an amazing filter for the price offered on K&F Concept. It is clearly the BEST CPL filter I have ever used over the years...including those from well-known and very expensive German manufacturers.
The filter and the inclusions rate an unequivocal STRONG FIVE STAR rating from me, along with my honest and VERY hearty recommendation! You cannot go wrong with this filter if you need a CPL!
Simply SUPERB!
Happy Shooting!

I used this for an Iceland trip and was able to capture some phenomenal images when it was on my glass (primarily a Tamron 28-75mm f/2.8 with a Sony a7ii).

The ring itself is a little stiff, but that's great for a polarizer - means you have one less thing to worry about when framing your shot in that this won't turn a few degrees on you. In terms of negative impacts to image quality, I can't notice many but I'm not exactly a pixel peeper.

For my uses, this fit the bill!

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.
