52mm Magnetic Lens Filter Kit MCUV + CPL + ND1000 + Adapter Ring

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 seems good. It was a great choice!...It allows me to capture long water shots on bright sunny days. It's not a variable and it's too dark for those dark, cloudy days. You will want a different filter for that. The filter is well made and easy to put on my lenses. It also comes with a nice case to store and carry. Images are crisp and clear with no vignetting like you might get with some filters. Excellent value for money, definitely value for money.

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.

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

As a photographer, I use filters, but it's not always easy to put on or remove depending on the situation. But with this system, it becomes so simple that it is almost instantaneous.
The product is of very good construction quality and comes with a 4 pockets pouch very well made and resistant against possible blows. It can be attached to the belt thanks to a scratch. The kit consists of two screw rings, one UV and a vacuum on which you can attach the CPL filter or the ND1000.
I 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 staggering. Here are the rendered with the CPL filter on the left and the CPL+ ND 1000 on the right. With the filters, there is no loss of dipping, and the color drift is almost zero. The CPL filter polarizes perfectly and the ND 1000 filter is very amazing by its performance, it is very thin which limits vignetting, a plus. Using both together, it is better to avoid the ultra-wide angle focal lengths, but from 16mm, no worries, we can add them up. In addition, they are compatible with my sun visor, I was able to put on and remove them without having to remove it very easily because the magnetic force is perfectly dosed.
Really very satisfied with this first release, I hope that other magnetic filters intermediate with this system will come out soon to complete the offer.
If there were magnetic lens caps, it would be great.
This is a very good investment and the price is more than correct given the quality and results obtained.

 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.

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!!

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.
