About 75% of the filters that I have used have been K&F. And as all of the other filters, this one does not disappoint. I love the magnetic base. I purchased other magnetic filters simply because I love the way the filter held. The filter is clear and does not affect my pictures negatively. I will surely recommend this product.

K&F somehow made the best magnetic filter ring on the market. It holds very well and the fit is perfect. I have rarely used a cpl until this one it has stayed glued on my 35mm lens. The materials are excellent quality and the filter itself presents no color cast. I really hope k&f make more filters magnetic.

The filter does a great job of polarizing so I can see through glass on set, and doesn't have any color casting to it. it's easy to adjust still, and the magnetic mount threads on easily. The magnets are decently strong, so I never felt worried about the filter falling off, as well

knew that there was no industry standard in these magnetic filter specifications, and so magnetic filters (and also magnetic thread adapter rings and magnetic lens caps) from different manufacturers don't always "stick" when mixed together. So I was concerned whether this K&F magnetic CPL filter and K&F magnetic thread adapter ring are compatible with the Urth-brand magnetic filters and a magnetic thread adapter that I already was using. I am happy to report that, at least in this 77mm filter size that I tested, the K&F and Urth magnetic filters seem totally compatible / interchangeable: - I was able to attach Urth magnetic filters to this K&F magnetic thread adapter - I was able to attach this K&F CPL filter to an Urth magnetic thread adapter. - I was able to stack the K&F and Urth filters magnetically Aside from the magnetic properties, this K&F CPL filter seem to work as expected. It has nice and even anti-reflection coatings, and didn't seem to impart any offensive/unexpected color cast as it removed glare from shiny leaves and darkened blue sky. I have no complaints. So I would like to give this K&F magnetic CPL filter + magnetic thread adapter 5 stars.

First things first, its maximum polarizing effect is not as great as my b&w polarizer. But that's not really important. Why? Because I rarely go for maximum polarized effect; I adjust my filter to what looks "right." More importantly, it's much easier to use than my other polarizer. The magnetic mount lets me pop it in with complete ease in microseconds. Plus, because of all the twisting I'd do with my previous polarizer, it sometimes would get stuck so tight, it was a pain to take off (when you try to twist it off, your grip would slip because you'd be twisting the turning part of the filter). Not a deal killer by any means, a little elbow grease would get it off, but again you lose precious seconds which often leads me to not putting it on my camera it at all, a lot of times. With this, that's a non-issue. I should add that, even though I mentioned that the max polarizing effect isn't quite as strong as my other filter, it's still quite strong, and the optical quality is terrific as well. Highly recommended.

This is a beautiful filter that’s part of their easy magnetic attachment system and it comes with a magnetic adapter which can be used for most brands of magnetic filters. fit and finisher excellence and the optical quality is additionally excellent. The polarizing ring turns very smoothly and easily without slipping on the magnet. This is a very precision machine piece. It’s excellent at eliminating glare which can be very difficult to remove with post processing software.

Review of K&F Concept 52mm Magnetic CPL Filter + Magnetic Basic Ring Kit Waterproof Scratch Resistant Circular Polarizer Filter with 28 Multi-Coatings for Camera Lens (Nano-X Series) I love the idea of a magnetic filter ring, it makes filter changing so quick and easy. This item is well machined, had good optics and slips together very smoothly. Now that I have a magnetic ring I can look for magnetic filters for my 52mm lenses. Or if I get a different magnetic filter and ring I can setup my other 52 mm camera lens and change filters between them. Nice equipment. I can recommend this.

They can make the difference between a good picture and a great picture. I just started getting the magnetic filters that just pop in place without having to threading them on. So far they are super handy especially with neutral density filters where you cant always see what your shooting because they are so dark. They cost a bit but they seem worth it It is a good idea to get a large diameter filter and adapters for them in case you have other size lenses or if you upgrade to a larger lenses. I hope my review is helpful.

bought this as I needed a good high quality CPL since I switched from Canon to Fujifilm last year. When I shot Canon R bodies I used the drop in filter system that Canon made and I had the ND as well as their CPL and now I have a good one to use with my new Fujifilm gear. As always I recommend buying larger than your largest lens needs and then get a set of step up rings so you can use the one filter with ALL your lenses.

have a DJI Osmo Action camera, early version, and next to the Go Pro the colors of the grass, blue skies etc. seems a bit washed out. I love the deep blue sea and sky, and the lush slightly deeper color in the lawns; that is exactly what this filter gives you. It comes with a magnetic ring. Be sure to order the right size, or have an adapter set that will enable you to use it on different lenses. The magnetic base is included so you can swap it out/take it off in a millisecond, and put it back on the same. Overall quality is superb. Not much you can say about a filter that does what it is supposed to do, and does it very well. Highly recommended. PS: Getting it out of the tight-fitting box is a bit of a nightmare if you like to keep the compact fitting box intact. With all of the information on it, it makes it easy to identify what it is in your camera bag. Oh well, what comes out in the film is all that matters.
