Bought filters because they are magnetic, I am extremely pleased with them and recommend them for quick ease of use. Image quality is excellent.

Pros
- Easy to install and remove
- Magnetic adapter ring is compact enough to leave installed on lens
- Magnets work with other brands of magnetic lens caps and filters

Cons
- Circular polarizer filter sometimes doesn’t seat itself fully flat on the adapter ring, need to press down firmly to ensure a flat install
- Magnetic adapter ring doesn’t have any thread or place for a lens cap to grip, so lens caps fall off easily

This circular polarizer system is a great way to quickly add or remove a filter. The magnets hold well and also allow the polarizer to rotate smoothly to make adjustments for optimizable polarization.

I also have some Kase brand magnetic filters and lens caps that work with this system, and that was a nice bonus that they’re compatible.

The adapter ring doesn’t have any threads on it to help a spring-loaded lens cap to grip. That means lens caps will fall off easily when attached to just the magnetic adapter ring. The solution is to either install the circular polarizer filter with the lens cap or buy a separate magnetic lens cap that can attach directly to the adapter ring. Personally I like the magnetic lens caps.

As with any circular polarizer filter, you will lose some light and will need to compensate to brighten your exposure back to normal.

the magnetic mount and filters work fine. Only problems is that the filters won't allow for the lens shade to be attached. the filters are just a bit larger then the lens not allowing the lens shade to slide ove them and be attached
otherwise, i would have given it a 5* rating

I have used K&f magnetic filters before and the Polariser worked as well as those. Pretty decent for the money

The 62mm circular polarizer lens filter by K&F Concept is made in PRC (china). I did not notice any issues with fuzziness around the edges, the whole frame looks sharp. The filter does not have threads on the front side, only the back side. That makes this the outer most filter if stacking filters. The filter has some heft as it is made from glass and not plastic. This is a good filter despite the lack of versatility in the mounting.

Capturing the essence of a moment, that's what photography is all about. And when it comes to elevating your shots, the K&F Concept 82mm Magnetic Circular Polarizer Lens Filter is a true game-changer! From the moment I secured it onto my lens, a whole new world of possibilities unfolded.
This sleek and ultra-slim filter is a marvel of engineering, boasting 18 multi-layer coatings that effortlessly cut through glare and reflections. Whether I'm shooting landscapes or portraits, the polarized effect adds a depth and richness to my images that leaves me awestruck. But that's not all the magnetic design is a stroke of genius, allowing for seamless attachment and removal without any fuss. Say goodbye to the frustrations of traditional filters and embrace the future of photography with this ingenious creation from K&F Concept. Pros outweigh the cons, but the slightly higher price tag is a small price to pay for such outstanding quality.

These magnetic filters are awesome. No more worrying about the lens threads on the camera. If you've ever had a filter get 'stuck' on the lens, you know how frustrating that can be. With the magnetic filters, you can swap out the filter in about 10 seconds. I personally think the lens clarity is excellent. Very happy with this filter.

Glass is clean with no imperfections. The ring is machined perfectly and slides on to a 82mm Sigma art lens perfectly. 5/5 stars

The K&F Concept 67mm Magnetic Polarising Filter has been a game-changer for my photography. This ultra-slim, circular polarizing filter is perfect for my lens, thanks to its high-quality Japan optics and multi-coated design that minimizes reflections and enhances color saturation. The magnetic feature is incredibly convenient, making it easy to attach and remove without any hassle.

One of the best aspects is its ultra-slim profile, which doesn’t cause vignetting even on wide-angle shots. The multi-coating not only improves image quality but also provides effective protection for my lens. Plus, the included cleaning cloth is a thoughtful touch, ensuring that I can keep the filter spotless and maintain optimal performance.

Overall, this CPL filter has exceeded my expectations. It delivers vibrant colors and reduced glare, which significantly improves the clarity and contrast of my photos. If you’re looking for a reliable and easy-to-use polarizing filter for your lens, this one from K&F Concept is a solid choice.

I've absolutely loved all of the filters I've gotten from K&F. All of them have been perfectly clear, packaged great, and threaded perfectly across each setup I've used them on.
