This is a very good quality CPL that compares to my other filters by bigger brand names and more expensive brands. I have zero complaints about this CPL, I am unable to spot any color distortion, fringing or vignetting. The ultra low reflectivity is something I was looking for specifically in my Canon RF 200-800mm Lens and I am getting exactly what I want from this filter.
Definitely recommend this filter!

K&F Concept have always had excellent filters and this is no exception. Included with all of their filters is a quality case and microfiber cloth. This is for my Canon EF-L 200mm f/2.8L II USM lens and moment filter adapter when video recording with an iPhone.

I always use K&F Concept filters because they stand out for their high quality and ease of use. Since I got it, I've always carried it in my backpack because it makes a huge difference in photos, especially landscapes.
The polarizing effect is very noticeable: it eliminates annoying reflections in water or glass and enhances colors, especially the blue of the sky and clouds, which look much more vibrant and defined. The best thing is that it doesn't alter the natural color of the image, thanks to True Color technology. No yellowish tones like other cheaper filters.
As for optical quality, it's one of the best I've tried: 28 layers of coating that really help prevent unwanted reflections, vignetting, and scratches. It's also water resistant, which is appreciated outdoors.
In short, a great filter that shouldn't be missing from your photography backpack.

Hello folks!
K&F concept is a serious company. And I'll explain right away why I'm starting off so hot.
In 2024 I purchased, and I stress, purchased, not received as a sample with Amazon Vine, two K&F polarizing filters. Since it is a filter that is irreplaceable by any digital processing, I wanted to delve deeper into the quality of K&F polarizers, taking the basic Nano-k model and the top of the range, Nano-x.
Significant price difference, while remaining in the low end of the market, but surprisingly indistinguishable results.
Following my lukewarm review of the top of the range, compared to an enthusiastic one for the basic model, the company contacted me for some explanations: K&F's response was that the Nano-X promised greater scratch resistance and water repellency, but on the optical performance, they themselves admitted, between the lines, that I was right.
Well, it seems they woke up and launched an evolution of the Nano-X, which, this time, I was lucky enough to be able to try with the Vine program.
Finally, there is a difference, and it is clearly visible. The previous models had a slight, but present, tendency to turn green. Nothing tragic for the very cheap Nano-K, but decidedly annoying on the Nano-X.
Well, the green cast has disappeared. This time we are there, dear gentlemen of K&F.
The mechanics have also definitely improved. The sliding of the two rings that make up the filter is definitely more fluid than on the previous models, at least the ones I own.
The threading also seems definitely improved. With the K&F filters that I had purchased in the past, there could be some difficulty in unscrewing them, once mounted. This offers the right resistance, also to not unscrew by itself during the rotation of the polarizer, but a light force is enough to remove it easily.
So, unlike the previous model, which left me with a bit of a bad taste in my mouth regarding the optical performance and mechanical construction, this new Nano-X true color gets full marks.
P.S. just to clarify, a polarizing filter attenuates, and in some cases, eliminates reflections from non-metallic surfaces. So, in addition to eliminating reflections on glass and water, it attenuates the effect of atmospheric haze, improving the general sharpness of the photos and making the sky bluer.
But you have to know how to use it. If the orientation of the light is not at 90° to the subject or the sky, the effect may be less or non-existent.
For example, if you photograph with the sun behind you, the polarizing filter will have no effect on the color of the sky.
If you shoot with a wide-angle lens, the effect on the sky will not be uniform because the incidence of light will vary in the frame, due to the large field angle of the lens.
These are not defects of the filter you are using, but physical characteristics of all polarizing filters and you have to take them into account. In short, it is not a very easy filter to use, and often, those who do not know it, buy it and then criticize it without reason.

A lovely Concept 58mm True Colour Polarising Filter.
I love the colour balance it provides.
It's designed with a 28-layer Multi-Coated Polarised MRC Filter.
Super easy to clean and doesn't attract dust easily!
Overall, it is working nicely, and I am delighted!

I got this K&F Concept polarising filter to help reduce glare and improve contrast in my photos, and it does a great job. The colour balance is spot on, with no strange tints or shifts, which I’ve noticed with some cheaper filters in the past.
The build quality is solid, and the slim frame means there’s no vignetting even on wider lenses. It’s easy to rotate and adjust, and the multi-coating helps keep it free from fingerprints, water marks, and dust. The reduction in reflections is impressive, making it especially useful for landscapes and shots involving water or glass.
It’s a bit on the pricey side, but the quality makes it worth it.

K&F offers us this ultra good circular polarizing filter, a must for those who do landscape photography especially if there is water and that gives more saturation in the presence of flares and flashes of various kinds.
The filter is well built, good materials and the result is definitely above average. The price is reasonable if you consider that there are polarizers of the same quality at double the price.
To have and always carry with you for excursions.

I'm allowed to try out this polarizing filter as part of a Vine product review. I received it free of charge for this purpose, but this does not influence my review.
I've never worked with a filter before, and I'm simply thrilled.
I recently bought a digital SLR camera, and I'm getting more and more involved in the wonderful hobby of photography. Sooner or later, you can't avoid filters.
I'm impressed by how comprehensively this filter prevents reflections and unwanted light effects.
Highly recommended!
Star rating:
I only give five stars if I'm absolutely thrilled (exceeds expectations).
Four stars are given if everything is perfect for me, i.e., the product meets the expectations based on the description.
Three stars are given if there are defects, but the product is generally usable.
Two stars means that the product can no longer be used as expected due to its defects.
One star indicates a total failure; it is not possible to award fewer stars.

I received this item as part of my product testing program. This review is independent of this and is not influenced in any way by it. I rate it as if I had purchased it for myself, remaining completely objective.
A good CPL filter made of finished metal. Optical glass with a multi-nano coating. The thread is easy to attach and remove from the lens. Thanks to the internal thread, additional filters can also be used simultaneously. The photos are impressive. I'm very satisfied.
