All 3 filters for me are very useful. The stand-alone ring however, I'm wasn't sure how much I'll actually use it but surprisingly I just leave it on my lens unless it's pretty bad weather, which in turn I use the UV filter as a protective layer for the glass.The CPL filter works wonders and the ND filter is great for long exposer shots. the combination with the magnetic touch make this absolutely flawless. would recommend

I really like the convenience of this magnetic filter system. You only need to thread on the base ring and magnets do the rest. Makes it less likely to damage the threads of your lens if you don't have to keep putting on and removing a filter on every time you need to use it. I am using this with a 24-105mm full-frame lens and the base ring works with the lens cap and the hood although you probably need to remove the hood to snap on the filter because otherwise your fingers get in the way.
Each of the filters themselves are quite a bit heavier than the screw on K&F versions, probably because they need to make the filter ring out of a magnetic steel instead of aluminum. Whatever the reason, they feel a lot more premium than the regular K&F version.
In terms of performance, its a bit of a mixed bag. I don't have tremendous experience using CPL and ND filters (this is my first set) so I don't know what's considered good performance at a given price range.

Moving on, the CPL filter (photos looking out the window) has similar vignette to the ND filter at 24mm but appears to cut down quite a bit of reflections in my windows. Not much for me to point our here, it seems to do the job.
The set does come with a UV filter but I do not intend to use it unless I am in a rainy/dusty environment where my lens needs a bit more protection so I haven't tested it out yet.
For both the ND and the CPL filter, I did not detect any noticeable decrease in sharpness caused by using the filters.
I think the performance of these filters is acceptable. I am a little disappointed with the vignette but I have heard of much more expensive filters having similar issues so I don't want to be too hard on this set. All in all, for someone like me who does this for fun, I think its a great system to learn the basics until I can justify the move to something more premium.

I am absolutely satisfied with the overall package price performance is definitely right here the magnet is sufficiently strong, the bag offers good protection and can be fastened well with the double Velcro fastener and the eyelet for a hook I would buy the magnetic filter set again at any time

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.

Delighted with my 55mm magnetic filter kit. It consists of 4 components, an adapter, a UV filter, a polarizer filter and a ND1000 filter. Both the polarizer and the UV filter are threaded, so they can be screwed on the front of the lens, but they also have a magnetized part, so the rest of the filters can be magnetically attached to them. I have several types of filters, threaded, square and these. Without a doubt, the magnetic ones are my favourite filters, I am very happy with them as they are very comfortable to use, especially for that reason, for the comfort of use. It is very easy to put on and take off any of the filters. You leave the UV or the adapter and it's instantaneous to put on or take off any of the others. I always use the UV, which also has a thread on the outside so I can put the cap on, the thread is fine, but the cap stays on and doesn't fall off. This way, I always have the camera ready to attach any of the other filters quickly and easily.

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.

I own quite a few K&F Concept Products. They provide quality products without the hefty price tag we're used to see in the photography world.Let's talk about the filters individually first. All 3 filters are of top quality, at least on this price point/tier, as we're used to get from K&F Concept products:-The CPL Filter has no color shifting and performs as expected.-Same with the ND1000, although i don't use 10-stop filters that often (my most used filter is a VND Nano from K&F Concept) during my test it worked well, no cross present, even while using step-up rings.-The UV Filter has no color shifting and the main purpose these days of the UV filter is to protect the lens surface, BUT, It is where this VERY MINOR issue this kit has: The magnetic ring holder.The magnetic ring holder works great with the ND and the CPL, just not as good with the UV Filter, but it is not by ANY MEANS bad or i'd call it unsecure, at least not on the 82mm filter size version, your mileage may vary depending on the kit size you got as the magnetic surface may be different for your version, just the grip doesn't feel as tight as it does with the other two filters and there is a TINY bit of play, but not enough to warrant losing a star over it, i mean if you shake the camera at full strength you may drop it, but on regular usage i do not see it just falling off the ring holder.As the sum of all parts i'd 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 decided between 4 or 5 stars, i'll go with 5.

I am a photographer and I love adding accessories to my kit. One piece of the ‘kit’ that has been elusive to me is functional, easy-to-use lens filters. I have a great set of variable ND filters, but the one thing I keep struggling with is getting them lined up exactly right in order to screw them into the lens. K&F Concept, a surprising, budget-friendly accessory manufacturer has a really cool set of magnetic lens filters. The set comes with a soft-sided, waterproof carrying case, adapter ring, MCUV filter, CPL filter, and ND1000 filter. The idea behind this set is that you screw on one adapter, leave it on the lens, and then pop the filters on and off as you need them. You don't waste any time while shooting trying to get the filters lined up just right. I think this is a great filter system. The filters are well-made and high-quality.

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

This is something that I never expected to see since I use DSLR and lenses.
Honestly now, it makes a massive difference.
I am not talking about the filters because you can find these any time, I am saying here about the system itself which I find to be absolutely brilliant!
