I’ve had a generally good experience with K&F filters and this is no exception. The polarizer works well for my automotive shoots and doesn’t add some crazy cast over my images. It doesn’t feel cheap and performs as it should.

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 KF-Concept CPL polarizing filter is delivered in high-quality packaging. The filter is also located in a sleeve made of felt/imitation leather with a magnetic closure cap. A microfiber cloth is also included for cleaning the filter. The filter itself is a round filter made of tempered glass in the "slim" version. It is particularly compact and thin, which is particularly useful with compact lenses. The filter works excellently. There are no color fringes, air pockets, color casts or discolorations visible. The polarization effect can be easily and precisely adjusted on the side by screwing the filter. Conclusion At the time of my purchase, this polarizing filter cost EUR 179.00. High-quality glass filters in this quality class are usually significantly more expensive. So I think the price/performance ratio is very, very good. It's not for nothing that KF-Concept named this filter line Flagship - the filter is worth every cent and really is an excellent addition to my existing screw-on filters. So I'm giving it 5 stars and I hope my review was helpful

Appearance as soon as I opened the package, I slowly realized that the price was not only influenced by the polarizer itself. The presentation and packaging are reminiscent of a design product. The polarizing filter comes in a stylish slipcase with a magnetically lockable case. In theory, you could also use the included foldable stand to set up the packaging like a picture frame. Not an option for me personally, but you have to admit that the developers of the packaging went through the design concept from start to finish. It could hardly be more elegant. Personally, I would still prefer a robust hard case, but that's a matter of taste. Regarding the filter: I mainly use my polarizing filters in product photography and occasionally in real estate photography, mainly to combat reflections or to partially eliminate them. Anything I do right when I'm shooting takes less time later in post-processing. As you can see on the test images, you can keep surface reflections in check with a polarizing filter. In the meantime, reflections can also be reduced better with software, but you get easier and better results with a polarizing filter. A polarizing filter is still a must-have in some areas of application. The Nano X-Pro achieved very good results in my test and can keep up well with my existing polarizing filter. I haven't been able to test how well it reduces flares and ghosting, as I'm currently photographing very little landscape and outdoor scenes. For future outdoor use, it comes with the luggage. What I don't like is that the filter ring is a bit too cumbersome to turn. This bothers me, especially when it comes to freehand photography, which I do a lot. On the other hand, a ring that moves too easily is not good either. When the camera is on the tripod, the somewhat difficult turning doesn't bother me at all. As you can see, it's a matter of taste and basically not a negative point. Overall, a very high-quality polarizing filter that is very well made and works very well. On very tough photo trips, I would either pack it in a different case, otherwise I would be too worried about the expensive piece.

I've known K&F for a while now and have one or the other product from them (UV filter and camera backpack). For me, the brand was always technically good value for money and more in the middle price segment. But now they want to know and are penetrating into the high class area. A CPL filter is used for reflective environments such as water, panes and glasses or the sky. Exactly these reflections are taken out here and you manage to take pictures down to the bottom even with clear water. So for me, especially on vacation, it's always a filter. The filter comes very nicely packaged and is a lot of fun unpacking. Anyone who loves unboxing will get their full enjoyment here. The filter comes in a cloth/leather bag. Very nice in itself, but in my opinion a filter sits more snugly in the well-known plastic boxes. The inside of the packaging can be converted into a "picture frame". Funny idea but I think there are nicer ones. But let's get to the filter itself. Here I have to say again that the performance matches the price and is absolutely justified. Flawless workmanship, both on the filter thread, ring and glass. Only the ring is a bit difficult for me personally. If the filter doesn't fit snugly on the lens, it has happened to me that I unscrewed it instead of adjusting it. The glass is of the best quality and the optical performance cannot be distinguished from a CLP filter from the well-known competition. In summary, a very good filter in terms of quality and optical performance. It has weak points in the somewhat loose fixation in the storage bag and the stiff ring. For the price, I really hope that things like this don't happen. So unfortunately I have to deduct a star.

received the polarizing filter for free as part of the Vine program to test. Since mine from another manufacturer is already getting on in years and does not fit my most used lens, I was happy about it. Even the packaging is very high quality and the supplied bag is very well thought out and easy to handle. You can even make a pretty frame out of the packaging. A microfiber cloth for cleaning is also included. The filter does a good job removing annoying reflections and enhancing the colors in the image (green from the grass, blue from the sky and also white against a blue sky). For this reason, the filter is great for landscape photography. Naturally, the polarization filter reduces the light by up to several f-stops. However, this must generally be taken into account when using such filters. However, this is not a problem, especially when taking landscape photos with a tripod. The filter was inexplicably stuck (couldn't find any handling error or wedging) on the lens when first used. That's why I only gave it two stars in the rating. He also does not use force to remove. It could only be removed again using a special tool from a third-party provider. After that I changed the rating to 5 stars. Because the filter lost some color on the frame when I tried it without special tools, but it held up great and still worked great. Now and then I can't get it off when using it. But after I screwed something on the adjustment ring for the polarizing filter, it then came off again. Just not without problems. That's why I'm correcting my rating again! 4 stars this time. It's still a mystery to me why this works. You can hardly grab it because the back ring is so narrow that you can't grab it with your bare hands. In my opinion a design flaw! This high-quality filter offers good value for money.

Is a polarizing filter the same as a polarizing filter? No, that is not so. Polarizing filters polarize to a greater or lesser extent. That shows you the price you pay for it. But there are other things too: A really good filter does not have a light metal frame, because this could twist under pressure when screwing in and the filter could seize up. This polarizing filter has a heavy and precisely made brass mount, the rotary ring to bring the polarizing filter into the right position runs smoothly and smoothly. Additional corrugations on the socket prevent fingers from slipping when turning. This is also bitterly necessary, because the filter is designed as a "slim version" with a very short overall width in order to also be suitable for wide angles. The filter's coating looks impressive and I'm happy to believe that it's particularly effective at preventing reflections (although this could only really be proven in a comparative test). The polarization effect is very good and there is no color deviation in Lightroom. I have never owned a photographic filter that was so elaborately packaged - yes, almost "staged" - like this professional filter from the Chinese manufacturer Shenzen Zhuo Er. With this, the manufacturer wants to underscore its claim of being at the forefront of the market segment. I take it for granted that he can do that. In terms of manufacturing quality, the filter easily reaches every Heliopan or Rodenstock filter. Of course, it also costs accordingly. I'll be happy to buy a few more filters of this type - I've got a taste for them now. Do you automatically make better pictures by using such an expensive filter? Definitely not. If you were previously satisfied with your image results, this filter will not open up a "completely new world" to you. But if you're eager for every technical possibility to improve quality, then, yes, you should really consider switching to these fantastic filters.

An 82mm polarization filter from the K&F Concept brand from the Nano-X PRO series is supplied. Overall, I find the presentation very valuable, appealing and goes for me in the PRO area - the price too ;-). The unboxing was a WOW! experience for me. A filter that puts a smile on your face when you unpack it has to be good - ..and it is. I think the filter is really great! It is well made, makes a high-quality impression, can be easily screwed onto the Tamron 24-70mm 2.8f G2, the imaging performance is great and I don't see any dark spots, "ghosting" or the like at the edges (as with some other cheaper manufacturers /products). The reflections can already be taken out when taking pictures, which in turn reduces the tedious post-processing. I left the scratch test at this point, after all I want to use the good glass with maximum performance ;) I don't need a scratch on it for the time being, it will inevitably come by itself at some point. Now to the one catch: the packaging, i.e. the transport box, is not 100 % mine - why? Because I'm more of a hard-shell type, where I can put the filter. Nicely laid out in itself, but not quite as practical for me personally. Conclusion: for me, the polarizing filter is a great choice. Certainly not a snapper at first glance, but you also get a high-quality product for such a price. I have already mentioned the weakness with the case mentioned above. It's not really my thing, but ultimately it's also a matter of taste. In the end, what counts is the quality of the polarizing filter, and it's great!

The filter is packed in a small design object. The bag is well thought out from front to back and just as well designed. But: a lint-free hard case would be much better. Unfortunately that was nothing. A filter is always a compromise. I put a layer between the object (light) and the lens. Thus, quality is inevitably lost. In this case, the loss is very low, which speaks for a very good quality of the glass. The reflection of the surfaces is visibly reduced. The ambitious price matches the performance of the filter. However, I don't use the filter bag, but take a hard plastic box - just like always.
