Great polarising effect, strong magnet. Couldn't be happier. Bought the 77 and 82mm for my RF 15-30 f2.8 and RF24 - 100 f4 landscape lenses.

Nice quality and easy to use, especially when I need to take it off faster.

I got this for my new Lumix S5ii. This is definitely a high-quality filter. It is well machined and has excellent optical quality. I've seen these filters sold at renowned photography stores. It does not disappoint. I really love the magnetic design.

The K&F magnetic ring easily fit my lens. Like all K&F products this filter is well machined and works well with the lens. The optical quality is excellent. Often polarizing filters cause vignetting on wide angle lenses. As can be seen in my photos the K&F CPL filter does not vignette my 24mm lens. Note how the filter brings out the contrast in the clouds and offers a pleasing depth to the photos.

The K&F 58mm magnetic CPL filter comes in a classic small filter box. This is a great thing, it is much more convenient to have a small filter in a small filter box. So many times I see smaller filters like a 58mm in a box made for large 77mm filters which makes them impractical to fit in the pocket.

This is my first magnetic filter and I think I may have to switch fully over to magnetic filters. I found that I like them. It makes since with a polarizer anyway. There is something satisfying with the snap when the the filter snaps into place.
The polarizer does its job, adds contrast to the sky as you would expect. No moire or distortion, etc.

First the good. This is a well machined and properly threaded magnetic ring with a multi-coat, optically clear polarized filter. The filter rotates easily to find optimal polarization. Results are as expected when taking pictures in the right conditions. Darker, richer blue skies especially in typical landscape shots. The magnetic ring allows for quick exchange with other filters or stacking of multiple filters.

My issue is that my standard lens cap for a Sony 24-105 F4 G OSS lens does not work on either the filter sitting inside the magnetic ring or on the magnetic ring itself. I get it. It is a kit that needs a K&F cap.

Now it gets interesting. Search on Amazon for just the lens cap that fits the CPL? That lens cap is pictured on other listings and has a red ring and red logo on the outside. That cap seems to come with a three-piece kit with the magnetic ring and a filter or a two-piece kit with the filter and cap. I looked on both Amazon and K&F Concept. No lens cap as a standalone purchase?

This means that you have to spend additional money on a two-piece set with an additional filter and the lens cap or a three-piece set with the magnetic ring and filter to get the lens cap. Really? It makes little sense to have a two-piece kit that only includes a magnetic ring and filter, especially if this is your first K&F set. Bottom line? Be sure to order the set with a lens cap if it is important to you. 5/5 for optical clarity and filter functionality. No lens cap? I need one. Disappointed. So, minus a star. 4/5.

I had a magnetic adapter and lens cap, but not a CPL. So this is my first real filter. It is a circular Polarizer which you turn to achieve different angles to polarize the light into the lens for different effects, mainly to eliminate reflections in water, glass, and chrome. Usually in a CPL, you turn the filter and it really doesn't "stay" it just turns and you are careful when taking the picture. In this magnetic one, you turn the filter, and it "stays" when you stop turning, due to the magnetic adapter, which is a nice surprise. What is a little disconcerting is that you are basically turning the filter within the magnetic adapter/holder, so there is friction and small scraping noises as you turn the filter. Of course there would be as you are basically rubbing two pieces of metal together, but at first, I wasn't expecting that. But it works, and it is very handy to have a CPL I can just slap on the lens and peel off when I am not needing it. I love this magnetic innovation and filter holders, so I think I will be using this CPL instead of my usual screw-in CPL.

I wasn't sure about the whole magnetic ring adapter concept - I imagined my 40-dollar polarizer getting knocked off and rolling down the sidewalk - but the magnet is pretty strong, and after playing around for a few minutes, I'm a fan. The magnetic adapter makes it easy to pop the polarizer off for shots without the filter, or for swapping it for a different filter if you have others that are compatible.
The filter comes well packaged in a nice reusable plastic case, with a fitted foam insert, that protects it well, which is good because Amazon just tossed it into an envelop for shipping.
The two pictures I posted here don't do the polarizer justice. The sky wasn't particularly dramatic this afternoon, but the difference with the polarizer vs. without it is noticeable - the trees are a deeper, richer shade of green, and the clouds stand out somewhat better.
The lens caps for both my Nikon lenses snap right on with the filter installed or with just the adapter ring in place.
The only concern I have with this set is the price seems kind of high to me. With Tiffen polarizers selling for about half the price of this one, and with K&F Concept selling the same filter in a standard screw-on style for 10 bucks less than this one, I don't know that the magnetic mount is that big a selling point for me. If you switch filters a lot, I guess it could make sense, but for a casual user like me, as much as I like it, it's just not worth it.

I needed a way to protect my lens, and this polarizing filter came up. I like that the filter is easily removable and that in the ecosystem I'm able to swap out filters by simply pulling it off making quick changes for subtle effects a breeze. It has a recess so your lens cover can still clip on, but it's not going to be rock solid firmly mounted due to the magnets not being strong enough to hold both the filter and lens cover so be mindful of that when storing in your bag or chucking your camera over your shoulder. I like that the packaging can be repurposed as the case for this filter, so I don't need to worry about it getting damaged if I am to remove it from my lens.
Well made, magnets could be stronger.
