49mm Magnetic Lens Filter Kit UV+CPL+ND1000+Magnetic Adapter Ring 4 in 1 Quick Swap System Nano-Xcel Series

"The Magnetic Lens Filter from K&F Concept is a must-have accessory for any photographer. Highly recommended! "

"Say goodbye to the hassle of screw-on filters! The Magnetic Lens Filter is so convenient and easy to use. Love it!"

These are so easy to use and the quality is fantastic - both the build quality and the picture quality. I can't see any colour cast whatsoever from both the CPL & ND filter. I think you would really need to pixel peep to see any sharpness difference, and even then I'm not sure there is.
Being able to attach the filters to both the UV filter and filter ring is really clever - I keep the UV on my 24-70 F4 and the filter thread ring on 16-35 F4 so it makes it even faster to clip on the filters no matter what lens I use.
Since the ND isn't variable, there's no dark X. And no vignetting at 16mm, unlike when I use my square filter set.

The downsides that I see at the moment:
- You can't replace the filter thread on its own, so if you break or lose it, you have to buy a new set. I contacted support but was asked to pay $16 for delivery of a new thread....
- The range of NDs isn't as big as a square filter system (yet) and again I'm not sure if you can buy them as singles or whether it's just part of these kits

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 off, 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!

►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!!

The K&F Concept Nano Series magnetic filter kit is really extremely practical. The kit that contains the filters has a compact size, which allows us to carry it in our backpack, sacrificing very little space. The weight is extremely light, which is really useful for those who do long hikes where the weight of the equipment, after several hours, begins to be felt. Installing and removing filters is nothing short of lightning; in seconds you can easily mount the three filters and in as many seconds they can be removed. The grip of the magnets is really good and therefore there is no fear of ending up with filters falling off during the shooting or transport phase. WHO IS RECOMMENDED TO In conclusion, I highly recommend this value for money filter kit to: - anyone looking for a first filter kit to begin the creative experience; - those looking for an excellent relationship between quality, size and weight; - those looking for maximum practicality during filming and composition.

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.

Admittedly, the system of magnetic filters is not entirely new and I cannot say who copied from whom, but I already know K&F from their very good lens adapters and solid tripods. And since I've been flirting with magnetic round filters for a long time, but up to now the prices for such a system have seemed too steep to me, I was of course interested that K&F now also offers something like this.

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.

In addition to square filters, I have now also bought the inexpensive magnetic filter holder set. I can only say: topp. However, I lack the possibility of obtaining ND 8 and ND 64 (magnetic), because only ND 1000 and polarizing filters are available. A second glass-filled filter holder is included, which is super with adapter ring for a second lens size can be kept permanently and still! fits in the super handy case. For now, this inexpensive set with magnetic holder is enough for me; if I have further requirements, I will probably switch to the "large" filter holder system from another manufacturer (approx. 400 euros with three ND filters). Which photographer does not know this "want to have?". In short, the post on YT by Riko Best has convinced me. Would I recommend it? Yes, to anyone who wants to work with gray filters now and then. LG
