I really like the concept of this set of filters. I’m not the most coordinated person, and switching filters in the field requires some coordination, so I have just been using a single filter - and it shows in my photos. I really like that this set really requires very little coordination. I’ve been able to quickly and easily switch filters as the lighting changes.The set comes in a nice padded fabric case with individual pockets and a Velcro strap to attach to a belt.The set includes 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 seems a bit loose when on the adapter. The other filters fit much better, but they fit just as well on the UV filter, so I’ve chosen to skip the adapter ring and just thread the UV filter to my lens and attach the other filters to this one. It obviously means an added layer of glass when setup this way though.Anyway, I like this set and would recommend it.

This is a more than successful set that is worth every euro, not only for newcomers to the subject. Ambitious users will also find a good alternative to the filters of the established brands.
It really remains to hope that K&F brings more of these magnetic filters on the market, because I would like to have another ND8 and ND64.
Therefore, I can, with a clear conscience, give a very clear buy recommendation.

I love using filters, the polarizing filter in forests or on the coast I find it essential, also when there is hard light, when there are low moving clouds and in rivers, waterfalls and coasts I love using the ND filter. In situations where I don't require the polarizing filter or ND filter, I like to use Ultraviolet to protect the lens.

The truth is that sometimes it is cumbersome to use them, especially in adverse situations when, for example, it is cold and you are wearing gloves, there is a lot of wind, you are very close to a waterfall and there is spray, etc, etc. It has also happened to me on occasion that I have left the filter on the lens for a while and then it has been difficult for me to remove it, so I have found it interesting to try the magnetic K&F filters, it seems to me a comfortable system with a good quality / price.

In the package comes a case with the 3 filters (a polarizer, a 10-stop ND and UV) and a screw adapter, the case can be placed on the belt to always have the filters at hand.
The use is quite easy, you simply have to place the thread adapter and place the filter in it, as it is magnetic it immediately catches it and from there it does not move, if I want to change the filter it is as simple as removing it and putting it on, you can see 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, for example the polarizer and the ND to take out moving clouds with polarized light avoiding unnecessary reflections.

In short, I have loved the system of changing the filters so quickly, when I am traveling or in uncomfortable situations I will appreciate it.

I have bought and used a number of K&F CONCEPT product for my photography over the years and have always found them to be a great balance of quality and value, and this lens kit is no exception.
I think it's an awesome basic filter kit for landscape photographers.

►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!

How easy is now? Very very easy and I explain why.
I use filters for filming outside which sometimes can be challenging because of the light, the sun comes up from the clouds, manual settings, everyting over exposed which is very bad for video.

►My lens diameter is 67mm so I got those. You have to screw the ring and then based on what you want to get you just have to attach the filters.........you DONT have to screw them one by one which saves you a lot of time.

Now, the advantage?
You avoid moving your camera is you want to change the filter!!! This is the most important feature I would say!!
I keep my camera in one spot and 100% doesnt have to move AT ALL!! So with this magnetic system i just remove one filter and add another, easy as that. I dont have to screw anything!!!

►What you get? A nice pouch, a filter ring(the magnetic one), 1 uv filter, 1 cpl and one ND1000. You already know what they do because you are all photographers so its easy.

Build quality? Good, clean design, slim filters, nice pouch(has a ring so you can attach it to the bag, tripod and so on.

►VERY IMPORTANT!!
You cannot attach all 3 filters at the same time!!
ONLY one by one so dont try to attach more because they might fall and you damage them.

How strong is the magnet?
Once attached to the lens even if you run with the camera in your hand you will not lose the filter so dont worry.

►Easy to remove? I would recommend to use both hands to make sure you remove the filters properly.
The most interesting filter for my type of work is the ND1000, makes a massive difference. I dont have to explain things like filming at f2.8 when it is bright outside + shutter at 60 for 30fps because you already know what I am talking about.

Make sure you choose the right filter size, check and double check your lens size.

►Overall experience?
Impressive techology!!

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.

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 construction quality and it comes with a very well made and resistant 4 pocket pouch against possible knocks. It can be attached to the belt with a Velcro. The kit is composed of two screw rings, one UV and one vacuum on which the CPL filter or the ND1000 can be fixed.
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 just astounding. 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 color drift is almost zero. The CPL filter polarizes perfectly and the ND 1000 filter is very surprising in terms of its performance, it is very thin which limits vignetting, a plus. By using the two together, it is better to avoid ultra wide angle focal lengths, but from 16mm, no worries, you can add them. In addition, they are compatible with my sun visor, I was able to put them on and take them off without having to take them off very easily because the magnetic force is perfectly dosed.
Really very satisfied with this first release, I hope that other intermediate magnetic filters with this system will be released soon to complete the offer.
If there were magnetic lens caps, that would be awesome.
It is a very good investment and the price is more than correct given the quality and the results obtained.

As a landscape photographer, I found this filter system really interesting. Unlike screw filters, these filters can be applied and removed in a fraction of a second, while unlike plate filters they are much less bulky, lighter and, of course, much quicker to install. The K&F Concept Nano Series magnetic filter kit is extremely practical. The case containing the filters is compact in size, which allows us to carry it in our backpacks with very little space sacrificed.
The weight is extremely light, which is really useful for long excursions where the weight of the equipment starts to be felt after several hours.
The installation and removal of the filters is lightning fast, to say the least; in a matter of seconds you can easily fit all three filters and, in just as many seconds, remove them.
The holding power of the magnets is really good and therefore there is no fear of finding yourself with filters that fall during shooting or transport.

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 am happy with this purchase.

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.
