Have bought me in addition to square filters now also the inexpensive magnetic filter holder set. I can only say: top. However, I miss the possibility of getting ND 8 and ND 64 (magnetic), because only ND 1000 and polarizing filters are available. A second glass-filled filter holder is included, which can be kept permanently with an adapter ring for a second lens size and still! fits into the super handy case. For the time being, this inexpensive set with magnetic holder is enough for me; if I have further requirements, I will probably switch to the "big" filter holder system from another manufacturer (approx. 400 euros with three ND filters). Which photographer doesn't know this "want to have?". In short: Riko Best's contribution on YT convinced me. Would I recommend it? Yes, to anyone who wants to work with grey filters now and then.

INTROI bought these filters to replace others I already had (always K&F concept always purchased here on Amazon) to have something practical, comfortable and light to carry with me that would adapt to my new outdoor philosophy and family needs (practicality and lightness). What I discovered was a wonderful surprise. These filters and the case they come with are not only practical but are also well made, have good optical performance and do not present chromatic aberrations. For me they represent a real REVOLUTION and now I'll explain why...[

Generally speaking, I've become a fan of K&F's filters. They are, and this kit is no exception, competitively priced quality filters.But this "kit" is a bit disappointing and, in hindsight, I guess I would have preferred to just buy the 3 individual filters.On the plus side is the obvious: being able to swap among the three included filters is quick and easy. Attaching the filter adapter is simple, and selecting the filter (or choosing no filter) really does take just a second or two.But here are some negatives to think about before you choose this kit over individual filter purchase:- The UV filter does not attach as strongly as the other filters. It sloshes around a bit within the adapter ring, and I'm actually a bit worried that a slight bump could cause it to pop out. By contrast, the ND and CPL filters attach much more firmly. (In case it matters, I'm using the 77mm size.)- The filters are "stackable", allowing for some creative possibiliities, but not entirely so. For example, the CPL filter can be seated firmly inside the UV filter, but not the other way around. So, your one or two seconds of switching/stacking filters may be a little clumsier than needed. It would have been nice if this kit had uniformly designed filter rings, so that all of them worked the same way.- It would have made so much sense if the adapter ring were also threaded so that I could screw on other non-kit filters. That seems like a missed opportnity on K&F's part. In other words, if I want to take one of my traditional 77mm filters, it would be nice if it could simply screw it onto the adapter ring. But instead, I have to unscrew the adapter ring to make way for my old filters. Perhaps this is K&F's way of nudging me to consider buying more of their magnetic filters to add to my kit.So, in short: the individual filters, as far as filters go, are great. But this kit has plenty of room for improvement.

I purchased this K&F Concept 67mm Magnetic Lens Filter Kit for my Tamron 28-75 f2.8. These filters work great and fit on my new camera.quality looks good.It was a great choice!.... It allows me to capture long exposure water shots on bright, sunny days. It's not a variable and it's too dark for those dark dreary, overcast days. You'll want a different filter for that. The filter is well made and easy to thread onto my lenses. It also comes with a nice case to store and carry. The images come out clear and sharp with no vignetting, like you might get with some filters. Great value, definitely worth the money. I tried to add more than one photo for examples, but couldn't. I'll try to edit and add more later. I am happy with this purchase.

As a landscape photographer, I found this filter system really interesting. Unlike screw filters, these filters are applied and removed in a fraction of a second, while unlike plate filters they are much less bulky, lighter and, obviously, much quicker to install. PACKAGING AND ATTENTION TO DETAILS Filters are delivered inside a comfortable and really well made case with four compartments. The case, in the back, has a hook and loop buckle that we can use to attach it to our tripod or to our trousers and, also, a metal ring so that it can be attached to our backpack, to the tripod column or wherever we prefer. Finally, the zip closure of the case is proof against rain or water infiltration. The filters are contained and protected individually within special sachets to avoid any potential damage. CONSTRUCTION These magnetic filters from the Nano Series by K&F Concept are made of optical glass perfectly resistant to water, oil and dust. The external frame is made of slightly knurled aluminum to allow an excellent grip. They are extremely thin and, even by mounting all three filters at the same time (UV, CPL and ND1000), the thickness is extremely limited. UV FILTER In the photographs I took with the UV filter there are no color alterations, no loss of sharpness and details and no casts of any kind.POLARIZING FILTERThis polarizing filter provides a pleasant overall contrast to the image, increasing the contrast between the individual colors and saturating them without exaggerating. Furthermore, it provides a very slight warm cast which, personally, I don't mind but which is easily correctable in post-production.ND1000 FILTERThe first thing that strikes you when using this ND filter is that it produces a slight - but present - warm cast. Personally I think it is not a problem as it can be removed with one click in post-production. Finally, the overall sharpness as well as the details of the image are not altered. CPL + ND1000 FILTER. I consider the CPL + ND1000 combination very interesting. In fact, the polarization effect reduces the warm cast of the ND1000 filter and also provides a pleasant saturation and a soft contrast overall and between the colors of the final image. In terms of sharpness and details, there are no significant deteriorations. However, there is a slight vignetting. PRACTICALITY The K&F Concept Nano Series magnetic filter kit is truly extremely practical. The case that contains the filters has compact dimensions, which allows us to carry it in our backpack sacrificing very little space. The weight is extremely light, which is really useful for those who go on long excursions where the weight of the equipment, after several hours, it starts to make itself felt. The installation and removal of the filters is nothing short of lightning-fast; in a matter of seconds you can easily mount all three filters and, in just as many seconds, they can be removed. The hold of the magnets is really good and therefore there is no fear of finding yourself with filters that fall during the installation phase. shutter or transport. TO WHOM IT IS RECOMMENDED In conclusion, I would strongly recommend this filter kit with an excellent quality/price ratio to: - those looking for a first filter kit to start experimenting with creativity; - those looking for an excellent value between quality, size and weight; - those looking for maximum convenience when shooting and composing.

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.

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

The filters work well individually, with no noticeable colour cast on the ND filter and only a slight warming of the image with the CPL. The magnets appear to be strong enough, the CPL rotates smoothly and I wouldn't worry about them falling off.A minor issue is that the pouch hasn't been stitched properly, so it's a little bit deformed on one side. But it's still perfectly usable, and is small enough to fit comfortably in my camera bag.Overall I'm happy with the performance of the filters, but I don't seem to be able to stack the CPL and the ND without a diagonal darkening of the image. This depends on the rotation of the CPL, and it's either from top-left to bottom-right, or top-right to bottom-left. Disappointing, but it's probably rare that I'm stacking the filters.

I had a great time with these magnetic filters, purchased with the 82mm diameter as it is the largest thread among my lenses, so that I can also adapt them with the appropriate adapters to other lenses with a smaller thread, excellent quality, I recommend them
