40.5mm MCUV+CPL+ND1000+Adapter Ring Magnetic 4 in 1 Lens Filter Kit Waterproof Scratch-Resistant Anti-Reflection with Filter Pouch
SKU: SKU.2119
Great product but when you buy a single filter you get a lens cap with it but you do not when you buy the entire set.

There is nothing to dislike about these filters. The Magnetic Feature just makes it so easy to go from filter to filter as needed. It works exactly as a photographer would expect them to and works as advertised on the Amazon Website. Please note that the mounting ring has to be removed to reverse the lens hood for storage (it will fit in the normal use direction with the ring on), and the lens standard cap will not fit. But in reality, this should not be a problem for the seasoned photographer who knows how to stow the lens components.

My circular filter kit for each lens size includes a protective UV, a CPL and ND 10 and 6 stop. The K&F kits contain all but the 6 stop. The 6 stop can be ordered separately, though at this time only from the manufacturer's website.
For any given size kit, the K&F Concept magnetic kit costs far far less than would top line individual threaded filters from other manufacturers (Breakthrough Photography, B+W, Hoya HD3, etc.). Yet the optical qualities of these K&F have been tested and are equal to the best. My own experience is that the K&F coatings are also just as effective at repelling water droplets as are my most expensive filters.
Having used K&F Concept magnetic filters in two sizes for a few months I am loving the speed of filter changes and the absence of thread jamming when I stack an ND on a CPL.
My only criticism is the lack of knurling on the front edge of the CPL frame. Magnetic CPL filters do not need or have a two piece construction. The entire filter is rotated in its magnetic attachment, which is fine but remains a two-finger grasping maneuver. To rotate the CPL you'll need to temporarily remove the lens hood. Maybe had K&F added knurling to the from edge a fingertip would suffice, but there is more friction opposing rotation than in a well made two piece threaded CPL. Off course you could attached your old threaded CPL to the lens, screw the open ring magnetic adapter onto the CPL, then add your NDs magnetically. You'd risk jamming the adapter ring to the front threads of your old CPL. I'm not going to do this.
The protective UV is only meant to be attached directly to the lens threads. It is a lens protector. It does not magnetically attach atop the other filters or the open adapter ring. You are give two threaded adapters, one is just an open magnetized frame. The other has the protective glass. The CPL or ND can be clicked onto this protective filter, but not the other way around. My advice is to use the protective UV when facing blowing sand or salt laden ocean mist (and when shooting from a Russian reindeer sleigh where showered by flying feces).
The included pouch is well made and easy to use. If you buy kits in multiple sizes you can even combine them into one pouch by storing the filters magnetically stacked and assigning each compartment of one pouch to a different diameter.

I love that this set includes UV, polarizing and ND filters all in one set. Comes with a storage pack. Very easy to attach. I love the magnetic attachment. This is so much easier than screwing on each filter. After having another brand and type of filter getting stuck on my lens, this was a welcomed change. Great innovation. Great glass quality.

Amazing quality product. The filters fit perfectly. They don't fall off even with the weight of the lens cap on them. I didn't use the adapter ring. I put the UV filter onto my lens as an everyday filter and lens protector. I then just put the polarising filter over it when I need it. The filter fits perfectly. Even with the two filters stacked I have no problems putting the lens hood on. There is also no vignette with my 24-70mm Nikon lens. I'm very happy with this filter system. Innovative!

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

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. PS The filter comparison photos have not been edited and are therefore the original file, exported directly from RAW to JPG format.

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.
