This CPL filter performed really well when used on my most recent vehicle rig. I was most concerned with the reflections that the windshield would produce at any given moment throughout the shoot. Thanks to this filter, I was able to drastically reduce the glare and focus on my subject who sat inside the car.
The filter itself is quite practical to use. Although it is a bit tough to remove when using step-up/step-down rings if you tighten it too much, it's generally a good rule of thumb to not overtighten any filters. In this instance, I just wanted to make sure everything was incredibly secured as the rig would be in motion, but otherwise for normal scenarios I wouldn't have had that issue at all.
Overall, I do think it's well worth the cost. I've used cheaper alternatives that haven't really offered the same result as this CPL filter by K&F Concept. Personally, I believe that sometimes using cheap gear ultimately cheapens the results and overall quality of some videos. In this instance, K&F Concept did an exceptional job given the price. Yes it's definitely premium, but it's well worth the cost.

Aunque tengo un filtro de esta misma marca que hace su función correctamente, no permite modificar la luz y el contraste. Este filtro sí lo permite, aunque sutilmente, permite girar suavemente la lente una vez acoplado y modificar en luz, contraste y color la percepción de la imagen. No es un cambio con mucha variación, pero permite retocar levemente la intensidad con que se capta una imagen.
Se le podía poner un punto negativo por el precio, pero, en mi opinión, es una valoración personal y relativa.
La calidad es muy buena y cumple perfectamente su cometido.

If you're used to cheap $10 filters just to protect your lens the price is eye watering for sure.
But this is a quality filter from top to bottom. I normally ignore packaging aesthetics but thats the first thing that stood out. I thought there was a watch inside. From box to the filter pouch - Quality. They even threw in a cleaning cloth. Normally youre on your own with that.
As for thr filter itself, doing a side by side with my cheap filters there a noticrable difference in detail. The filter itself is textured and grooved to reduce need for a filter wrench. The glass even spins inside of the ring so you dont overtighten. The 67 thread covers a wide range of lenses I have but Ill be using this for landscapes. One small knock on this is that theres not much depth to the filter so my lens cap doesnt securely settle in and ultimatley can bump off.
Still one of the best filters out there.

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.

I started photography back in the film days, when digital post processing was not an option. Consequently, filters were a must. I have always had circular polarizers available for all of my landscape and outdoor work
glass. The K & F Concepts CP is relatively expensive, but why buy high end lenses and skimp on the filters?
The packaging and presentation is befitting the high quality glass enclosed. This filter is simply the best quality polarizer I have used to date. I highly recommend this item, it is worth the price, and you will not be disappointed.

Transparency notice:
The product was made available to me free of charge as an evaluation sample, free of any influence or expectations. My review is based solely on my personal assessment and experience of using the product.
Review:
For quick readers, I'll preface my review, below I'll explain the details of my decision making, my impressions of the product.
I only make a minimal deduction of points and award 5 stars, i.e. 5 stars rounded up.
My only criticism is that the filter rotates slightly too slowly, i.e. its operation when it is screwed onto the lens, but I hope that will subside a bit over time. No, the turn isn't slow, but it's a bit tough, I expect a slightly smoother movement here.
Workmanship:
The slim frame is of very good quality, precisely processed and painted. I like slim filters, they build up less high on the lens and therefore do not limit its viewing angle, especially with a strong wide angle.
Slim filters can have the disadvantage of being more difficult to handle, as the grip ring is very thin. It is helpful here if it is handy and that is exactly what the K&F filter is.
I can grasp the filter very well and see no problem even with wet fingers.
The glass in the filter is of very high quality, optical glass, very precisely processed and absolutely flat, and has also been coated several times.
First, pick up the filter and look through it, preferably against strong contrasts and straight lines, such as a façade.
Here you can see that you don't see any glitches. I don't notice any distortion, the image is absolutely flat, over the entire surface of the filter, and I don't see any color distortions, I'm very satisfied.
It looks no different when I screw the filter onto my lens, but here is another aspect, possible reflections, but that is exactly what a polarization filter is supposed to eliminate.
In terms of image effect, this is absolutely undisputed, whether on a water surface or on windows, reflections are suppressed very well, as expected. But there is another aspect and that is the reflections on and behind the filter towards the lens when backlight comes in at an acute angle due to small punctual light sources. I don't see any reflections here, which speaks for the very good coating and glass quality of the filter.
I am very pleasantly surprised by the packaging of the filter and that starts with the attractive outer packaging in a high-quality slipcase.
It contains a flip case with magnetic closure, it is very decorative and practical, much higher quality and more elegant than the commonly used plastic boxes.
Conclusion: The K&F polarizing filter is not
a bargain at just under €150, but it is inexpensive in the sense of the word and is clearly placed in the premium segment. The processing quality itself is just as impeccable as the optical imaging performance on the lens. The included case is very attractive.
Only the somewhat slow adjustment of the orientation minimally disturbs the overall impression, so I subtract half a star for this. In the overall impression, this only plays a subordinate role and leads me to an almost unrestricted purchase recommendation.
Thank you so much for your attention when reading my review. If you'd like, feel free to give me some feedback, I'd be happy to hear from you.

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!

I dislike the fact that my lens cap no longer stays in, and I can’t remove the filter from my camera now that it is in.I attempted to contact K&F and the webpage is not available.Just a little frustrated right now.Hopefully someone will get back to me before I can no longer return it. That is if I will even be able to remove it to return it.
