Happy with my 55mm Magnetic Filter Kit. It consists of 4 components, an adapter, a UV filter, a polarizing filter and an ND1000 filter. Both the polarizer and UV are threaded so they can be threaded onto the front of the lens, but they also have a magnetic part and the rest of the filters can be magnetically placed on top. Combinations for using CPL and ND1000 can be: -Adapter+CPL, Adapter+ND1000 or Adapter + CPL + ND1000 -UV filter +CPL, UV filter + ND1000, UV+CPL+ND1000 filter They are packed in a padded cover and supplied with reverse zip to prevent some water seeping in when it rains. It can be clipped on belt or other place for convenient to use or carry. I have different types of filters, threads, squares and these. Undoubtedly, magnets are my favorite filters, I am very happy with them because they are very convenient to use, especially for the ease of use. It is very easy to install and remove any of the filters. You leave the UV or the adapter and it's instant to place or remove one of the others. I always have the UV which is also screwed on the outside to be able to put the lid up, the thread is thin but the lid is fixed and will not fall off. This way I always have the camera ready to insert one of the other filters quickly and easily. As for image quality, I have few complaints, I didn't appreciate the loss of sharpness or any dominant color. I was able to use both UV+CPL+ND1000 up to 12mm on my APSC camera with no vignetting. The filter I use the most is the ND1000 and it is very easy to use. Set the parameters you want for the photo and focus, change the camera to manual focus so the focus is locked, and place the ND1000. Now you see everything dark and you have to change the weather. What weather am I using? Very simple, take the time you have and multiply it by 1000. A 1/125 photo with no filter should take around 8 seconds to get a similar exposure. If you are looking for good quality filters that will not affect your image and are very convenient to carry and use, I would definitely buy magnetic ones. Carrying squares is a hustle at times and threading them is a lot more awkward, apart from the risk of them falling out, I'm a bit handcuffed and it's happened to me several times threaded. No problem with these at the moment and very happy. I leave you a video and some photos that I hope will help you!

Many voices will say, such cheap filters simply can't reach the quality of a brand filter and also I was someone who would have affirmed this immediately until now, so convinced was I of my B&W, Rodenstock, Haida and Co. filters. But now the surprise: the K&F filters do not show any conspicuities. No unnatural colour shifts, no clear loss of sharpness, hardly any flare or ghosting, simply nothing where I would say at first glance that it would be a reason for exclusion. And I think this fact has opened my eyes.

really like the concept of this filter set. I'm not the most coordinated person and switching filters on the spot requires some coordination, so I just used a single filter - and it shows up in my photos. I really like that this set really requires very little coordination. I was able to quickly and easily change filters when the lighting changed. The set comes in a nice padded fabric case with individual pockets and a Velcro strap for attaching to a belt. The set contains three magnetic filters and an adapter ring. The lightest filter is a UV filter that looks completely clear. Like the adapter ring, this filter is threaded. It is the only filter that is threaded and is also the only filter that appears a bit loose when attaching the adapter. The other filters fit much better but fit the UV filter just as well, so I decided to skip the adapter ring and just thread the UV filter onto my lens and attach the other filters to it. It obviously means an extra layer of glass when set up this way. Anyway, I like this set and would recommend it.

own some K&F Concept Products. They offer quality products without the high price that we are used to in the world of photography. Let's talk about the filters individually first. All 3 filters are of the highest quality, at least at this price point/level, as we have come to expect from K&F Concept products: - The CPL filter has no color shift and works as expected. -Same for the ND1000, although I don't often use 10-stop filters during my testing (my most used filter is a VND Nano from K&F Concept) it worked well, no cross present even when step-up -Rings were used. -The UV filter has no color shift and the main purpose of the UV filter nowadays is to protect the lens surface BUT where this kit has VERY MINOR problem: The magnetic ring holder. The magnetic ring holder works great with the ND and the CPL, just not so well with the UV filter, but it is by no means bad or I would call it unsafe, at least not on the 82mm filter size version, your mileage may vary Size of the kit will vary as the magnetic finish may be different on your version, only the grip doesn't feel as tight as the other two filters and there is a SMALL bit of play but not enough to justify a star over it lost, I mean if you shake the camera with full force you might drop them, but with regular use I don't see them just falling off the ring holder. As a sum of all parts I would say this was almost perfect. This kit complements my VND ND2-400 and includes everything I need to cover all my filters along my step up rings. The UV filter thing doesn't make it lose a star but maybe half so I'd say 4.5 but since there's no option for that if I had to choose between 4 or 5 stars I'll go with 5.

I shoot in various elements and destinations where the lighting is different and filters are needed to achieve optimal results. I use the traditional screw-on filters but find it very time consuming especially the way it has to be perfectly aligned with your lens which takes up to a few minutes for each one when I could miss the opportunity of my shot. I find this set of K&F filters to be a great choice for me. I am by no means a professional and I take pictures for fun with my Nikon D850 and these filters have worked great for me. The magnetic adapter ring is easy to screw onto the lens and the lenses stick to it well. These glasses work great in the rain and are not only waterproof, but also water beading. I had no problems with fogging between the lens and the filter. They are packaged in a hard case, each in its own slot. I find this to be excellent value for all the different lenses offered in this set and I am extremely happy with it.

really like the convenience of this magnetic filter system. All you have to do is thread onto the base ring and magnets do the rest. Makes it less likely to damage your lens' threads if you don't have to put on and remove a filter every time you need to use it. I use this with a full frame 24-105mm lens and the base ring works with the lens cap and hood, although you'll probably have to remove the hood to snap the filter or your fingers will get in the way. Each of the filters themselves are slightly heavier than the bolt on K&F versions, probably because they have to make the filter ring out of a magnetic steel instead of aluminium. Whatever the reason, they feel a lot more premium than the regular K&F version. In terms of performance, it's a bit of a mixed bag. I don't have tremendous experience with CPL and ND filters (this is my first set) so I don't know what would be considered good performance in a given price range. Let's start with the ND: it seems close if not a full 10 stops, which is great; the previous K&F screw 10 stop ND which I returned with only about 8 stops in practice. The ND has a noticeable color cast (see: in-camera photos of the sea). The ND image that brought the raw files into Lightroom had 26 more dots of magenta tint and was 1000K warmer than the unfiltered image. This cast was relatively easy to correct, although the colors weren't exactly the same. Less correctable was the 24mm vignette, which needs to be cropped out. With my lens at least, a quick crop test indicated I lose about 1mm of focal length to the vignette. Note that because the filter is magnetic, there is a small amount of float between the filter and the lens, so the vignette is not always symmetrical or consistent from use to next. In aggregate, the CPL filter (photos looking out the window) has a similar vignette to the ND filter at 24mm, but seems to reduce some reflections in my windows. Not much for me to point out ours here, it seems to do the job. The set comes with a UV filter, but I don't plan on using it unless I'm in a rainy/dusty environment where my lens needs a bit more protection, so I haven't tested it yet. For both the ND and CPL filters, I didn't notice any noticeable decrease in sharpness caused by using the filters. However, due to the burst of color with the ND filter, I recommend either shooting in RAW or setting your white balance before putting on the filter. For the price ($110), I think the performance of these filters is acceptable. I'm a little disappointed with the vignette, but I've heard of much more expensive filters that have similar issues, so I don't want to be too harsh on this set. All in all, for someone like me who does this for fun, I think it's a great system to learn the basics until I can justify upgrading to something premium. If you're a pro and making money from your photos, then maybe look into something more upscale like Freewell, or invest the time to create a preset to fix the color cast.

I've had these lens filter kit for a few months now. Unfortunately, the magnetic base ring got warped probably from pressure on my bag. They replaced it without any hassle. I would suggest keeping the base ring in a non-bendable case which is what I will be doing from now on. I would definitely buy from this seller again!

Typical of my experience with K&F products, these are excellent filters. They are just as good as a few other more expensive, popular and similar products. No color casts, well made and just works as described. Save your money and buy them from the most popular brands.

I needed a more travel-friendly set of filters to take with me on my hikes that would be too bulky to use my square filters. Having these filters in its own soft pouch was perfect and didn't take up much room in my camera cube. The magnets were strong as they held while I prepared my composition - sometimes in the rain and on uneven ground.

This is a kit,the combinations to use CPL and ND1000 can be:
-Adapter+CPL, Adapter+ND1000 or Adapter + CPL + ND1000.
-UV Filter + CPL, UV Filter + ND1000, UV Filter + CPL + ND1000, UV Filter+CPL+ND1000

Comes in a padded case with a reverse zip to prevent any water from getting inside in case of rain. It can be clipped on the belt or anywhere else for comfortable use or transport.

As far as image quality is concerned I have few complaints, I haven't noticed any loss of sharpness or colour cast. I have been able to use both the UV+CPL+ND1000 up to 12mm on my APSC camera without vignetting.
