Love these 3 magnetic filters, and the included magnetic ring with "threads" so I can use magnetic filters on my more conventional cameras. I use them on my iPhone 13 ProMax "Small Rig" (which is also amazing).The ONLY reason I'm giving these fantastic filters 4 stars instead of 5 is that the set that they sent me has a UV filter "with threads" and it just doesn't work with the magnetic mount. Other than that, however, these are perfect, and it is simply brilliant that you can change filters in under 2 seconds.Not such a big deal though, I have other 52mm lenses I can use the threaded UV on. But still... wish the order would have had the threadless UV.

I had been wanting to try a magnetic filter system for a while so I'm glad I got my hands on these. All the magnets work well and it's easy to screw on the adapter onto your lens. I personally only really use the ND filter, but the other 2 filters could stack on no problem and without any degrading in image quality or color.

I was able to look closely at high resolution RAW files of photos I took using the ND filter and they looked extremely clean. The little carrying case is a nice touch as well.

One suggestion is maybe adding a 6 stop ND filter to the set. There were a couple times where the 10 stop was just a little too much light blocking for me.

I would definitely recommend this to most photographers as a great and easy all around filter system

You get what you pay for

trabajan super bien en mi lente , me enamore de ellos

This concept is revolutionary! The filters are of very good quality, solid, delivered with a very good quality pouch as well. Very easy to use, the ring is screwed onto the lens in 2 seconds and then the filters are magnetized. I have been able to test lots of times and never has a filter come loose! Additionally in this kit there are the 3 main filters and essential to have. I recommend

Just when you thought... who would reinvent the wheel? K&F did it so well! I have the bevy of traditional filters and have always been screwing them on and off, carrying them with me, etc. All the usual ways we all use. That's what caught my eye when I saw "magnetic" and although... eh, seems weird. But I'm always ready for life when it comes to those little things, so I gave these a try. And now I find if I had to screw my filters on it would drive me crazy. This is a MUCH BETTER mousetrap for filter play! I swap out filters more often and use them more than I normally would. The magnets are strong and the filters are what you expect them to be. So far I love these. They just clip on, you screw on the magnetic ring and then the filters clip onto it. Your lens cap goes on top of the filter, so if you don't want the filter, I take it upon myself to take it with the lens cap and set it aside until I need it. If you use or swap out filters a lot, do yourself a favor and get these! I'm about to order a few more sets for my other lenses.

As a landscape photographer, I found this filter system very interesting. Unlike screw filters, these filters are applied and removed in a fraction of a second, while unlike panel filters, they are much less bulky, lighter and of course much quicker to install. PACKAGING AND ATTENTION TO DETAIL The filters are supplied in a comfortable and really well behaved four compartment pencil case. The case on the back has a tear-off buckle that allows us to attach it to our tripod or pants, and also a metal ring so that it can be attached to our backpack, to the tripod column or wherever we prefer. Finally, the zipper of the pencil case is rainproof or water leakage. The filters are contained and protected in special bags to avoid possible damage. CONSTRUCTION These magnetic filters from K&F Concept's Nano series are made of optical glass, which is perfectly resistant to water, oil and dust. The outer frame is made of lightly knurled aluminum to allow for an excellent grip. They are extremely thin and even if all three filters are mounted at the same time (UV, CPL and ND1000), the thickness is extremely small. UV FILTER In the photos I took with the UV filter, there is no color shift, no loss of sharpness and detail, and no dominance. POLARIZING FILTER This polarizing filter provides a pleasing overall contrast to the image, increasing the contrast between individual colors and saturating them without exaggeration. In addition, it offers a very light, warm dominant that it doesn't mind in person, but can easily be corrected in post-production. FILTER ND1000 The first thing that strikes you when using this ND filter is that it produces a slight - but present - hot dominant. Personally I think it's not a problem as it can be removed with one click in post production. After all, the overall sharpness as well as the details of the image are not changed. CPL+ND1000 FILTER I think the CPL+ND1000 coupled is very interesting. In fact, the effect of polarization reduces the hot dominant of the ND1000 filter and also provides a pleasant saturation and a soft overall contrast between the colors of the final image. In terms of sharpness and detail, there is no significant deterioration. On the other hand, there is a slight vignetting. PRACTICALITY The K&F Concept Nano Series Magnetic Filter Kit is extremely practical. The pencil case that contains the filters has a compact size that allows us to carry it in our backpack while sacrificing very little space. The weight is extremely light, which is very useful for those who go on long hikes, where the weight of the equipment can be felt after several hours. Installing and removing filters is nothing short of lightning. You can easily mount all three filters in seconds and remove them in as many seconds as possible. The hold of the magnets is really good and therefore there is no fear of finding yourself with filters that fall during the recording or transport phase. WHO TO RECOMMEND IN CONCLUSION, I would strongly recommend this filter set, excellent value for money: - those who are looking for a first filter set to experience creativity; - those looking for an excellent ratio between quality, size and weight; - those looking for maximum practicality in recording and composition.

love using filters, the polarizing filter in forests or on the coast I find it essential even when there is harsh light when low clouds are moving and in rivers, waterfalls and coast I love the ND filter. In situations where the polarizing filter or ND filter is not needed, I like to use ultraviolet to protect the lens. The truth is sometimes awkward to wear them, especially in adverse situations where, for example, it's cold and you're wearing gloves, there's a lot of wind, you're very close to a waterfall, and there's spray, etc. It has also happened to me once that I put the filter on the target for a while and then took it out so I found it interesting to try the K&F magnetic filters, I find it a comfortable system with a good one Price-performance ratio. The package includes a case with the 3 filters (a polarizer, a 10-step ND and UV) and a screw adapter, the case can be placed on the belt to always have the filters at hand. Using it is pretty simple, just attach the threaded adapter and place the filter on top as it's magnetic catches it instantly and from there it doesn't move. If I want to change the filter so easily it's as easy as removing and inserting you can watch the video where I record the simple process. The good thing about this system is that both the adapter and the filters are thin and you can also place two filters at the same time, e.g. B. the polarizer and ND to remove moving clouds with polarized light, eliminating unnecessary reflections. In summary, I liked that the system can change the filter so quickly when I'm traveling or in uncomfortable situations, I would appreciate it.

This filter system is really great for a quick on/off in certain photo situations. I ordered it for my 24mm lens. Disappointment came quickly. Because the filters gave me a circular image on my monitor :(. Unfortunately, that's a pity. Well, I think for small-angle photography, e.g. 50mm or so, it could be a good system, because the quality of the glasses is high in my eyes, but how said, only usable to a limited extent Went back K & F rectangular filters were added.
