While my particular polarizer did seem to have a blemish that caused it to not work with my camera lens, K&F were very quick to offer support and refund my purchase. I value this empathy for the customer very highly and was completely impressed by K&F in that regard.

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!

This filter does a wonderful job of reducing glare and making blue skies richer.

recently purchased the K&F Concept 67mm Circular Polarizers Filter Super Slim with 36 Multi-Layer Coatings and I'm so impressed. It's amazing how much of a difference this filter makes to my photos - in terms of clarity, sharpness and colour vibrancy. It's super slim, yet incredibly strong and durable. I love the 36 multi-layer coatings which give me amazing results every time. The images are crystal clear, thanks to the high definition coating. The colors come out vibrant and the polarizing effects are stunning.

This is a really nice polarizer and it works fantastic, as you would expect at this price point. It really just looks and feels high quality. Just be very careful when installing that you don't crossthread it, because I apparently did and now the filter is stuck on my lens :-( I will be leaving it on all the time because the camera shop I took it into said they are likely to break the filter trying to remove it. I don't think that is a fault of the filter though, just me not paying enough attention when I was putting it on.

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 Amazon. 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!

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.

Yeah you pay for it, but I’ve seen filters a lot more expensive that didn’t look as nice or work as well. After testing this I’ve seen absolutely no optical distortion whatsoever. It is a beautiful polarizing filter that is precision made as you can get. The threads are very easy to screw into the lens and the ring turns with buttery smoothness. This allows you to get any sort of Grady action you want to you in terms of polarization. This mechanism, the simple, is incredibly precise. The glass is absolutely perfectly flat as much as I’m able to measure it. And even using the laser test I saw no distortion whatsoever. This is supposed to have some kind of nano coating that makes it scratch resistant and also shed water much easier. I really hope not to test this. Every filter by this company has been first class all the way. Absolutely professional quality in this one is no different. I have a $300 German made polarizer and I don’t think you can tell the difference. I also have some other expensive ones that are not nearly as good as this. As for the German one, they look identical and they feel identical. And that’s at half the price. This company makes some first class stuff. I won’t have a reservation ever buying a K&F filter.

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.

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 don't 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.
