77mm Magnetic Lens Filter Kit MCUV + CPL + ND1000 + Adapter Ring

笆ｺ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.

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.

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!

K&F magnetic filters - CPL, UV, ND1000 - Excellent choice ! Packaging : 6,5 / 10 Nice case that keeps the filters together and protected. With velcro and ring to attach it to a belt or backpack. I don't particularly like the plastic box, I would have preferred something ecological like for other brands, but it's not something important in use so it weighs less on the judgment of the packaging. Handling: 9,5/10 Excellent workmanship, the filter is metal, threaded which fits well into every lens in my possession. Great that they are magnetic. In some conditions, screwing on a filter is very difficult and time consuming as well as the risk of it slipping out of your hands. In the case of the K&F magnetic filters, you just have to leave the holder mounted. If necessary, simply move the filter closer to the lens and it will attach itself powerfully and precisely. This feature is the main reason to buy these filters. Optical quality: 8/10 ND filter: Excellent sharpness: there is no loss of quality in high contrast areas. As with most ND filters, the filter has a purple/magenta cast, nothing that can't be corrected in post-production (see photos - doesn't work on PC just to show the quality of the filters). Slight vignetting, but really slight, nothing major. Score : 8/10 Polarizer / CPL Filter: Very very sharp filter, no loss of quality when editing. It tends to slightly "warm up" the images, but again nothing that can't be corrected with a touch in post-production. Excellent reduction of reflections on water and leaves affected by bright light. I don't like the effect of the sky being too intensified towards the Blue color (which also happens with all the other CPL filters I've tested). Important note in this case, it does not produce any additional flare compared to a use without filters UV filter: I never use UV filters because I find them useless except in case of danger for the lens (salt / water splashes / resins, sand). I must say however that this one has a good performance, it does not lose sharpness or worsen the flare compared to the lens without filter. Quality/Price: 9/10 For the general quality of the filters in question the price is LOW. Such a kit is suitable for both demanding amateurs and professionals because the weak points of these filters are few and in any case surmountable, while the strong points (speed of use and sharpness) are more important.

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.

The filter is mounted directly on the lens. You can always take it, it is not heavy and you will get great effects with it! Practice & optical quality: many voices will say, such inexpensive filters simply can not reach the quality of a brand filter and also I was until now someone who would have immediately affirmed this, so much I was convinced of my B&W, Rodenstock, Haida and Co. filters. But now the surprise, the K&F filters show no abnormalities. No unnatural color shifts, no clear loss of sharpness, hardly any flare and ghosting susceptibility, 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. Either K&F has found a manufacturer here who also does this for the brand companies, or as I think, they have simply inserted a second layer in the factory and instead of the brand name, simply lasered K&F on the filters.

I have always used the threaded filters on my camera, going back to my earliest days in photography. And we all know the effort it takes to change one of those filters - you have to unscrew the current filter and then screw the new one onto the lens, a process that takes a couple of minutes, at least. Not always ideal. With this set, you have two threaded options: an empty ring (with no filter or glass of any sort) or a threaded UV filter. The other two filters (a circular polarizer and a neutral density 1000) then attach to either of the previously mounted rings magnetically, so that switching filters just involves pulling the filter off and putting another in place - in just seconds. An excellent option in situations where you might want to change filters frequently. In addition, the set includes a convenient carry case, with separate, padded pockets for each of the filters. This case can be worn on a belt, or attached to camera strap (or in my case, the chest harness I use to carry my camera while hiking), which ensures that the filters are close at hand when you need them. My only complaint is that the magnets are a little bit too weak. At one point, as I was setting my camera down, I bumped the filter and it fell off. Luckily, it does not appear that the filter was scratched or otherwise damaged, but if you use these, you want to be aware that they can be knocked off relatively easily. You probably would never have a problem if you only used them in a studio environment, but if you use them outdoors, especially if you are moving around a lot, you want to be careful with them.

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
