58mm MCUV+CPL+ND1000+Adapter Ring Magnetic 4 in 1 Lens Filter Kit Waterproof Scratch-Resistant Anti-Reflection with Filter Pouch

Just when you thought....who would reinvent the wheel? K&F has def done it! I have the swarm of traditional filters and always screwed them on and off, carried them with me etc. All the standard ways we are all use to. This caught my eye when I saw "magnetic" and though.....eh, seems odd. But im always up for and easier life when it comes to those little things so i gave these a shot. And now, I find if i had to screw on my filters, it would drive me nuts. This is a MUCH MUCH better mousetrap to the filter game! I find myself swapping filters more often, and using these more than i usually would. The magnets are strong and the filters are what youd expect from them. So far i am LOVING these. They clip on easy, you screw on the magnet ring, and then the filters clip to it. Your lens cap goes on the filter, so if you dont want the filter, i tend to take it with the lens cap and put it to the side until i need it. If you use or swap filters a lot, do yourself a favor and get these! Im about to order a few more sets for my other lenses.

For now I can only express an opinion based on first impressions" very well-finished packaging, very well-made bag for storing the filters, also with magnetic closure and well-made compartments. Filters with strong magnetic attraction, which can be attached to the adapter, but which can also be magnetically superimposed on the UV filter, for those like me who leave it mounted constantly to protect the lens. I strongly suggest purchasing (separately) the magnetic lens cap, even if it is too expensive. But it is a useful accessory that is still worth the expense...

Effective and practical, the idea of magnet is absolutely magnificent

As a landscape photographer, I found this filter system really interesting. Unlike screw-on 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 DETAIL The filters are delivered inside a comfortable and very well made case with four compartments. The case, on the back, has a Velcro strap that we can use to attach it to our tripod or our trousers and, in addition, 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 rainproof or water infiltration proof. The filters are contained and protected individually inside special bags so as to avoid any potential damage. CONSTRUCTION These magnetic filters of 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 for an excellent grip. They are extremely thin and, even when 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 were no color alterations, no loss of sharpness and details and no dominants of any kind. POLARIZER FILTER This polarizer filter provides a pleasant overall contrast to the image, increases the contrast between the individual colors and saturates them without exaggerating. Furthermore, it provides a very light warm dominant which, personally, I don't mind but which is easily correctable in post-production. ND1000 FILTER The first thing that strikes you when using this ND filter is that it produces a light - but present - warm dominant. Personally, I think it's not a problem as it can be removed with a click in post-production. The overall sharpness as well as the details of the image, finally, are not altered. CPL + ND1000 FILTER I find the CPL + ND1000 combination very interesting. In fact, the polarization effect reduces the warm dominant of the ND1000 filter and also provides a pleasant saturation and a soft overall contrast and between the colors of the final image. In terms of sharpness and details, there is no significant deterioration. However, there is a slight vignetting. PRACTICALITY The Nano Series magnetic filter kit from K&F Concept is truly extremely practical. The case containing 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, begins to make itself felt. The installation and removal of the filters is nothing short of lightning-fast; in a handful of seconds you can easily mount all three filters and, in just as many seconds, you can remove them. The magnets hold really well and therefore there is no fear of finding yourself with filters that fall during the shooting or transport phase. WHO IS IT RECOMMENDED FOR In conclusion, I would highly 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 relationship between quality, size and weight; - those looking for maximum practicality during shooting and composition.

As a photographer, I use filters, but it's not always easy to put on or take off depending on the situation. But with this system, it becomes so simple that it's almost instantaneous. The product is of very good build quality and it comes with a very well-made 4-pocket pouch that is resistant to possible knocks. It can be attached to the belt with a Velcro fastener. The kit is composed of two screw-on rings, one UV and one empty on which you can attach the CPL filter or the ND1000. I really wanted to go and test this new product. First with the CPL filter alone and then with the CPL filter + the ND1000 together. The results are simply astonishing. Here are the renderings with the CPL filter on the left and the CPL + ND 1000 on the right. With the filters, there is no loss of sharpness, and the color drift is almost zero. The CPL filter polarizes perfectly and the ND 1000 filter is very surprising in its performance, it is very thin which limits vignetting, a plus. When using the two together, it is better to avoid ultra wide angle focal lengths, but from 16mm, no problem, you can add them together. In addition, they are compatible with my lens hood, I was able to put them on and take them off without having to remove it very easily because the magnetic force is perfectly balanced. Really very satisfied with this first outing, I hope that other intermediate magnetic filters with this system will come out soon to complete the offer. If there were magnetic lens caps, that would be great. It is a very good investment and the price is more than fair given the quality and the results obtained.

love using filters. I find the polarizing filter essential in forests or on the coast. I also love using an ND filter when there's harsh light, low moving clouds, and in rivers, waterfalls, and on the coast. In situations where I don't need a polarizing or ND filter, I like to use an UV filter to protect the lens. The truth is that sometimes it's cumbersome to use them, especially in adverse situations, such as when it's cold and you're wearing gloves, when it's windy, when you're very close to a waterfall and there's spray, etc. I've also left the filter on the lens for a while and had trouble removing it. That's why I thought it would be interesting to try the K&F magnetic filters. I think they're a convenient system with a good price/quality ratio. The package comes with a case with the three filters (a polarizing filter, a 10-stop ND filter, and a UV filter) and a screw-on adapter. The case can be attached to your belt so you always have the filters at hand. It's quite easy to use; you simply attach the threaded adapter and place the filter on it. Since it's magnetic, it immediately locks onto the filter and won't move. If you want to change the filter, it's as simple as removing and replacing it. You can watch the video where I recorded the simple process. The great thing about this system is that both the adapter and the filters are thin, and you can also attach two filters at once. For example, the polarizer and the ND filter, to capture moving clouds with polarized light, avoiding unnecessary reflections. In short, I loved the quick filter-changing system; I'll appreciate it when I'm traveling or in awkward situations.

Been wanting to try these K&F Concept Magnetic Filters since they were announced, I’m glad I purchased these they’re awesome, Super easy to use and swap when in the field, Just attach the magnetic ring to your lens and then it’s simply a case of attaching the filters with ease and swapping out, No hassle of having to screw the filters on and off, this is totally a game changer in my opinion, I own a fair bit of K&F gear and these are great quality as always, I have the k&f square filter kits but these are way easier, The supplied case is really nice too, They’re not cheap but you get what you pay for, I’m overall extremely happy

Bought this set for a Nikon p1000 along with another to have a complete set of filters. I was a little hesitant at first about the magnet but it works fantastic. I used the uv filter and cap but started carrying it with the uv filter the cpl filter, and cap stacked. I easily could remove the cap leaving the cpl in place for a photo or if I didn’t want the cpl filter I left it attached to the cap. I use lens cap leash so it made it super simple to use without fumbling the filter in and out of the case all the time. On that note the case is great fairly simple to use. I do mostly landscape and wildlife photography so need the nd filters occasionally but not all the time. I liked the set so much I purchased for my higher end Sony camera setup including the 2 lenses I use most the 24-240mm zoom and the 200-600mm zoom. The only downside is you have to order a set instead of individual filters. Highly recommend this set or others that fit your needs

Very convenient magnetic filters and lens cover. These appear to be of excellent quality and I use them exclusively on my lenses.

Used on rf 24 to 105 and 100 to 400 lenses
