This polarizer lens is great, it helps with water (or oily faces)! Easy to attach and remove from your lens and the threading is perfect.

It seems like a good idea, you can just turn the CPL on when you need it without any fiddly screwing - and the angle can be tested off-camera and then just snapped into place as desired. However, I found that neither the hollow adapter ring nor the CPL filter will accommodate my Olympus lens cap. It's OK if the filter doesn't - after all, it's only held on by magnets so that wouldn't do much good anyway. But I prefer to leave the adapter ring on the lens, the lens cap won't snap into place either. I have K&F branded filters on each of my lenses and K&F branded body caps and rear caps and even a K&F tripod that I'll be testing shortly. I've been happy with everything from this company to this product. I'm giving it four stars because if you can live without a lens cap, it's a pretty good product.

First the good. It's a well machined and properly threaded magnetic ring with a multi-layered optically clear polarizing filter. The filter is easy to rotate to find optimal polarization. Results are as expected when images are taken under the right conditions. Darker, richer blue skies, especially in typical landscape shots. The magnetic ring allows for quick swapping with other filters or stacking multiple filters. My issue is that my standard lens cap for a Sony 24-105 F4 G OSS lens won't work on the lens that's in the magnetic ring or the magnetic ring itself. I get it. It's a kit that requires a K&F cap. That's the exact same issue I had when reviewing a previous combo lens from K&F. Looking for the lens cap that goes with the CPL on Amazon? Extra, but available. This was the case almost a year ago when I reviewed a similar combo. I rarely use a lens out in the field without a cover available. Multiple protective cases? Another inconvenience. Sorry. Minus 2 stars for not fixing this issue. There's little point in having a two-piece kit that only includes a magnetic ring and a filter, especially if this is your first K&F kit. Bottom line? Be sure to order the kit with a lens cap if it's important to you. 5/5 for optical clarity and lens functionality. No lens cap? 3/5.

There are different types of CPL filters on the market, with different quality, finish and of course price. For those who do not want to spend so much, the products of this brand may be for you thanks to the excellent quality/price ratio. Even in this new type of filter with the new technology, particles were included, the quality is really excellent both constructively and functionally. We will have a magnetic filter that is applied to a ring previously screwed to our lens, so we can then apply any magnetic filters that we have in our possession. This filter has a special feature compared to the previous filters: the nanoparticle technology is a coating that guarantees excellent water resistance, that is, the small water droplets slide much more easily on the glass and do not leave any marks that could leave stains or halos on the lens. The filter itself, like all filters of this type, works very well. By turning the filter clockwise or counterclockwise we will apply more or less this type of filter that reduces or in any case reduces reflections and lights, especially on reflective surfaces such as glass and water or even on the hair, light reflections are eliminated, creating a more homogeneous and less luminous hair. A good product to always have with you on different occasions where reflections can damage our photographic creations.

must say that I'm glad I did as the filter is very high quality yet affordable. This filter features an aluminum filter frame as well as multi-coated optical glass elements on the front and back and comes with a magnetic filter mount. The quality and craftsmanship of the filter were evident once we received and inspected it. The filter glass remains clear and free of scratches, fingerprints or other marks. The magnetic mounting ring ensures a secure connection to my lenses and does not move or vibrate, and the polarizing wheel rotates effortlessly. The included leather storage pouch is also a plus when it comes to maintaining the condition of the filter when not in use. When I mounted and applied it on some of my photoshoots, especially landscape shots, this filter worked perfectly when the sky darkened, eliminating reflections and increasing the saturation and contrast of my shots, just like an effective polarizer should. The multi-coatings also help minimize flare and improve light transmission. Since the frame depth is practically paper-thin, it is possible to stack it behind other filters without losing image sharpness due to vignetting. In summary, I am pleased with the features of this K&F Concept magnetic circular polarizer. I was very happy to see that it offers all the utility I would expect from a filter of a much higher class and a much more expensive brand name." In summary, for photographers looking for a good CPL filter that is slim and budget-friendly, this is an excellent option.

bought the polarizing filter from K&F and I am absolutely delighted. This is not my first filter from K&F and I have to say that the quality of the company impresses me every time. The workmanship of the filter is first-class. It feels robust and high-quality, which is not always a given in this price range. K&F has once again managed to deliver a product that is not only functional but also aesthetically pleasing. The packaging is, as always with K&F, very good. The filter arrives safely packaged so that no damage occurs during transport. Everything is very neatly and professionally packaged, which I really appreciate. A special highlight is the magnetic attachment of the polarizing filter to the lens. This is ideal for quickly taking a picture without a filter without having to fiddle around for a long time. Simply remove and reattach - brilliant! The quality of the filter is incredibly good. When mounted and you turn it anti-clockwise, you can see the change straight away. In this case, the filter minimizes reflections, which makes a huge difference, especially on water or glass surfaces. The colors become more vibrant and the images clearer. I love this company and its products. K&F has never disappointed me. Today it's even on offer on Prime Day for just 20 euros - I just had to grab it! Conclusion: The polarizing filter from K&F is an absolute must-have for every photographer. It offers excellent quality, is easy to use and the magnetic attachment is a real plus point. Clearly recommended to buy!

I've been seeing these magnetic filters being marketed for a while now, so I decided to see if they were an improvement over the screw-in types. Bottom line...yes, they're worth it. The "receiver" ring is pretty thin. I'd suggest you attach it to the filter when you're not using it...in a safe place. I think it could get bent pretty easily otherwise. The knurling on the side could be deeper in my opinion, which is why I gave it 4 stars instead of 5. That being said, I really enjoyed using this filter. The polarization seemed nice and tight. The convenience of getting the filter in and out is what makes this product stand out...it only takes a second to put on and take off. I'll be looking for more magnetic filters from K&F from now on. Great show here...recommendable.

K&F continues to make great stuff. Fantastic CPL, seems to work with some other magnetic filters I own
