58mm Magnetic ND1000 Filter, HD Waterproof Scratch-Resistant Anti-Reflection, Nano-Xcel Series

Delighted with my 55mm magnetic filter kit. It is made up of 4 components, an adapter, a UV filter, a polarizing filter and an ND1000 filter. Both the polarizer and the UV have a thread, so they can be screwed onto the front of the lens, but they also have a magnetized part, so the rest of the filters can be placed magnetically on them.

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

They come in a padded cover with an inverted zipper to prevent some water from getting inside in case of rain. It can be clipped on your belt or anywhere else for convenient wearing or carrying.

I have several types of filters, threaded, square and these. Without a doubt, the magnetic ones are my favorite filters, I am super happy with them because they are very comfortable to use, especially for that reason, because of the ease 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 is instant to place or remove any of the others. I always have the UV, which also has a thread on the outside to be able to put the lid on, the thread is fine, but the lid remains fixed and does not fall off. In this way, I always have the camera ready to put any of the other filters quickly and easily.

In terms of image quality I have little complaint, I have not appreciated any loss of sharpness or any color cast. I have been able to use both the UV+CPL+ND1000 up to 12mm on my APSC camera without vignetting.

The filter I use the most is the ND1000 and it is very easy to use. Put the parameters you consider for the photo and focus, change the camera to manual focus so that the focus remains fixed, place the ND1000. Now you will see everything dark and you will have to change the time. What time do I use? Very simple, take the time you have set and multiply it by 1000. A 1/125 photo without a filter should be taken at approximately 8 seconds to obtain a similar exposure.

If what you are looking for are good quality filters that do not negatively affect your image and that are very comfortable to transport and use, I would definitely buy magnetic ones. Carrying the squares is sometimes a nuisance and the threaded ones are much more uncomfortable for me, in addition to the risk of them falling, I am a bit of a hand and it has already happened to me several times with the threaded ones. With these at the moment no problem and very happy.

I leave you a video and some photos that I hope will help you!

I took these filters to replace others I already had (always K&F concept always purchased here on Amazon) to have something practical, comfortable and light to carry around that fit my new philosophy for the outdoors and family needs (practicality and lightness). What I found was a wonderful surprise. These filters and the case with which they come are not only practical but are also well made, have good optical performance and have no chromatic aberrations. For me they represent a real REVOLUTION and now I'll explain why ...

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 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 great.
It is a very good investment and the price is more than correct given the quality and the results obtained.

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 tried to add more than one photo for examples, but couldn't. I'll try to edit and add more later.
I am happy with this purchase.

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).

►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!!

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

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.

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 to be 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.

Very good product for the price.
