I've become a big fan of K&F Concept filters. I have quite a few of their ND/VND filters and a Nano-X series CPL filter that is simply excellent. This is my first Nano-X Pro series filter and while the others are high quality this one is on another level entirely.The filter has a coated CNC machined brass that attaches to my lens smoothly and comes off without binding. It's slim to minimize any possibility of vignetting yet retains front threads to attach other filters. The edges are knurled and move with a slow liquid feel that helps the filter stay adjusted where you want it. The filter has K&F's Nano-X 36 layer MRC coating that resists glare, fingerprints, etc. and makes the filter easier to clean.It comes in a slim leather case with magnetic clasp and drawstring that lifts the filter up when you pull it - this is a great feature that helps keep fingerprints off the glass.As with my other K&F filters this one is extremely neutral without any color cast that I can detect. It has replaced my older B+W CPL filter in my bag and takes the place of my Freewell magnetic ND system when I want to travel light. It's K&F highest-end filter and compared to the competition it's cheaper and better quality making it a fantastic all-around value. Highly recommended.

A Circular Polarizer is one of the best filters to own. It allows you to block out light coming in perpendicular to your lens. And with a circular polarizer, you can easily rotate it to reduce or remove reflections and glare - or reduce the brightness of the sky.
It also comes with an attractive pouch for storage.
This one is a nice design. It is small form, which I prefer. It rotates smoothly. And most importantly, it doesn't degrade the image.
I prefer this CPL to my Tiffen one.

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.

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 keeps offering some amazing quality in both build and image reproduction. This filter does what it's supposed to and it also doesn't distort the image or color. No surprises here. What you see is what you get in an amazing package to carry it from place. Great CPL here.

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.

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.

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.
