THE ESSENTIAL SET
I'm very satisfied with this set of filters that I use for my landscape photos. Best value for money. Recommended!

Super easy to use and very good quality!
Happy with my 55mm
Magnetic Filter Kit. It consists of 4 components, an adapter, a UV
filter, a polarizing filter and an ND1000 filter. Both the polarizer and
UV are threaded so they can be threaded onto the front of the lens, but
they also have a magnetic part and the rest of the filters can be
magnetically placed on top. Combinations for using CPL and ND1000 can
be: -Adapter+CPL, Adapter+ND1000 or Adapter + CPL + ND1000 -UV filter
+CPL, UV filter + ND1000, UV+CPL+ND1000 filter They are packed in a
padded cover and supplied with reverse zip to prevent some water seeping
in when it rains. It can be clipped on belt or other place for
convenient to use or carry. I have different types of filters, threads,
squares and these. Undoubtedly, magnets are my favorite filters, I am
very happy with them because they are very convenient to use, especially
for the ease of use. It is very easy to install and remove any of the
filters. You leave the UV or the adapter and it's instant to place or
remove one of the others. I always have the UV which is also screwed on
the outside to be able to put the lid up, the thread is thin but the lid
is fixed and will not fall off. This way I always have the camera ready
to insert one of the other filters quickly and easily. As for image
quality, I have few complaints, I didn't appreciate the loss of
sharpness or any dominant color. I was able to use both UV+CPL+ND1000 up
to 12mm on my APSC camera with no vignetting. The filter I use the most
is the ND1000 and it is very easy to use. Set the parameters you want
for the photo and focus, change the camera to manual focus so the focus
is locked, and place the ND1000. Now you see everything dark and you
have to change the weather. What weather am I using? Very simple, take
the time you have and multiply it by 1000. A 1/125 photo with no filter
should take around 8 seconds to get a similar exposure. If you are
looking for good quality filters that will not affect your image and are
very convenient to carry and use, I would definitely buy magnetic ones.
Carrying squares is a hustle at times and threading them is a lot more
awkward, apart from the risk of them falling out, I'm a bit handcuffed
and it's happened to me several times threaded. No problem with these at
the moment and very happy. I leave you a video and some photos that I
hope will help you!

Very practical, but the MCUV filter fits loosely.
really like the
concept of this filter set. I'm not the most coordinated person and
switching filters on the spot requires some coordination, so I just used
a single filter - and it shows up in my photos. I really like that this
set really requires very little coordination. I was able to quickly and
easily change filters when the lighting changed. The set comes in a
nice padded fabric case with individual pockets and a Velcro strap for
attaching to a belt. The set contains 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 appears a bit
loose when attaching the adapter. The other filters fit much better but
fit the UV filter just as well, so I decided to skip the adapter ring
and just thread the UV filter onto my lens and attach the other filters
to it. It obviously means an extra layer of glass when set up this way.
Anyway, I like this set and would recommend it.

K&F Innovate again, almost perfect...
own some K&F
Concept Products. They offer quality products without the high price
that we are used to in the world of photography. Let's talk about the
filters individually first. All 3 filters are of the highest quality, at
least at this price point/level, as we have come to expect from K&F
Concept products: - The CPL filter has no color shift and works as
expected. -Same for the ND1000, although I don't often use 10-stop
filters during my testing (my most used filter is a VND Nano from
K&F Concept) it worked well, no cross present even when step-up
-Rings were used. -The UV filter has no color shift and the main purpose
of the UV filter nowadays is to protect the lens surface BUT where this
kit has VERY MINOR problem: The magnetic ring holder. The magnetic ring
holder works great with the ND and the CPL, just not so well with the
UV filter, but it is by no means bad or I would call it unsafe, at least
not on the 82mm filter size version, your mileage may vary Size of the
kit will vary as the magnetic finish may be different on your version,
only the grip doesn't feel as tight as the other two filters and there
is a SMALL bit of play but not enough to justify a star over it lost, I
mean if you shake the camera with full force you might drop them, but
with regular use I don't see them just falling off the ring holder. As a
sum of all parts I would 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 choose between 4 or 5 stars I'll go with 5.

Practical filter set with some color cast and vignetting
really like the
convenience of this magnetic filter system. All you have to do is thread
onto the base ring and magnets do the rest. Makes it less likely to
damage your lens' threads if you don't have to put on and remove a
filter every time you need to use it. I use this with a full frame
24-105mm lens and the base ring works with the lens cap and hood,
although you'll probably have to remove the hood to snap the filter or
your fingers will get in the way. Each of the filters themselves are
slightly heavier than the bolt on K&F versions, probably because
they have to make the filter ring out of a magnetic steel instead of
aluminium. Whatever the reason, they feel a lot more premium than the
regular K&F version. In terms of performance, it's a bit of a mixed
bag. I don't have tremendous experience with CPL and ND filters (this is
my first set) so I don't know what would be considered good performance
in a given price range. Let's start with the ND: it seems close if not a
full 10 stops, which is great; the previous K&F screw 10 stop ND
which I returned with only about 8 stops in practice. The ND has a
noticeable color cast (see: in-camera photos of the sea). The ND image
that brought the raw files into Lightroom had 26 more dots of magenta
tint and was 1000K warmer than the unfiltered image. This cast was
relatively easy to correct, although the colors weren't exactly the
same. Less correctable was the 24mm vignette, which needs to be cropped
out. With my lens at least, a quick crop test indicated I lose about 1mm
of focal length to the vignette. Note that because the filter is
magnetic, there is a small amount of float between the filter and the
lens, so the vignette is not always symmetrical or consistent from use
to next. In aggregate, the CPL filter (photos looking out the window)
has a similar vignette to the ND filter at 24mm, but seems to reduce
some reflections in my windows. Not much for me to point out ours here,
it seems to do the job. The set comes with a UV filter, but I don't plan
on using it unless I'm in a rainy/dusty environment where my lens needs
a bit more protection, so I haven't tested it yet. For both the ND and
CPL filters, I didn't notice any noticeable decrease in sharpness caused
by using the filters. However, due to the burst of color with the ND
filter, I recommend either shooting in RAW or setting your white balance
before putting on the filter. For the price ($110), I think the
performance of these filters is acceptable. I'm a little disappointed
with the vignette, but I've heard of much more expensive filters that
have similar issues, so I don't want to be too harsh on this set. All in
all, for someone like me who does this for fun, I think it's a great
system to learn the basics until I can justify upgrading to something
premium. If you're a pro and making money from your photos, then maybe
look into something more upscale like K&F Concept, or invest the
time to create a preset to fix the color cast.

Excellent, practical and light filters
As a landscape
photographer, I found this filter system very interesting. Unlike screw
filters, these filters are applied and removed in a fraction of a
second, while unlike panel filters, they are much less bulky, lighter
and of course much quicker to install. PACKAGING AND ATTENTION TO DETAIL
The filters are supplied in a comfortable and really well behaved four
compartment pencil case. The case on the back has a tear-off buckle that
allows us to attach it to our tripod or pants, and also a metal ring so
that it can be attached to our backpack, to the tripod column or
wherever we prefer. Finally, the zipper of the pencil case is rainproof
or water leakage. The filters are contained and protected in special
bags to avoid possible damage. CONSTRUCTION These magnetic filters from
K&F Concept's Nano series are made of optical glass, which is
perfectly resistant to water, oil and dust. The outer frame is made of
lightly knurled aluminum to allow for an excellent grip. They are
extremely thin and even if all three filters are mounted at the same
time (UV, CPL and ND1000), the thickness is extremely small. UV FILTER
In the photos I took with the UV filter, there is no color shift, no
loss of sharpness and detail, and no dominance. POLARIZING FILTER This
polarizing filter provides a pleasing overall contrast to the image,
increasing the contrast between individual colors and saturating them
without exaggeration. In addition, it offers a very light, warm dominant
that it doesn't mind in person, but can easily be corrected in
post-production. FILTER ND1000 The first thing that strikes you when
using this ND filter is that it produces a slight - but present - hot
dominant. Personally I think it's not a problem as it can be removed
with one click in post production. After all, the overall sharpness as
well as the details of the image are not changed. CPL+ND1000 FILTER I
think the CPL+ND1000 coupled is very interesting. In fact, the effect of
polarization reduces the hot dominant of the ND1000 filter and also
provides a pleasant saturation and a soft overall contrast between the
colors of the final image. In terms of sharpness and detail, there is no
significant deterioration. On the other hand, there is a slight
vignetting. PRACTICALITY The K&F Concept Nano Series Magnetic Filter
Kit is extremely practical. The pencil case that contains the filters
has a compact size that allows us to carry it in our backpack while
sacrificing very little space. The weight is extremely light, which is
very useful for those who go on long hikes, where the weight of the
equipment can be felt after several hours. Installing and removing
filters is nothing short of lightning. You can easily mount all three
filters in seconds and remove them in as many seconds as possible. The
hold of the magnets is really good and therefore there is no fear of
finding yourself with filters that fall during the recording or
transport phase. WHO TO RECOMMEND IN CONCLUSION, I would strongly
recommend this filter set, excellent value for money: - those who are
looking for a first filter set to experience creativity; - those looking
for an excellent ratio between quality, size and weight; - those
looking for maximum practicality in recording and composition. PS The
filter comparison photos have not been edited and are therefore the

I love the magnet system, it's very comfortable.
love using filters,
the polarizing filter in forests or on the coast I find it essential
even when there is harsh light when low clouds are moving and in rivers,
waterfalls and coast I love the ND filter. In situations where the
polarizing filter or ND filter is not needed, I like to use ultraviolet
to protect the lens. The truth is sometimes awkward to wear them,
especially in adverse situations where, for example, it's cold and
you're wearing gloves, there's a lot of wind, you're very close to a
waterfall, and there's spray, etc. It has also happened to me once that I
put the filter on the target for a while and then took it out so I
found it interesting to try the K&F magnetic filters, I find it a
comfortable system with a good one Price-performance ratio. The package
includes a case with the 3 filters (a polarizer, a 10-step ND and UV)
and a screw adapter, the case can be placed on the belt to always have
the filters at hand. Using it is pretty simple, just attach the threaded
adapter and place the filter on top as it's magnetic catches it
instantly and from there it doesn't move. If I want to change the filter
so easily it's as easy as removing and inserting you can watch 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, e.g. B. the polarizer and ND to
remove moving clouds with polarized light, eliminating unnecessary
reflections. In summary, I liked that the system can change the filter
so quickly when I'm traveling or in uncomfortable situations, I would
appreciate it.

For me, I'm a best buy. I'll explain why!
INTRO
I took these filters in place of others I already had (always K&F concept purchased here on Amazon) to have something practical, convenient and light to carry with me that adapted to my new philosophy for outdoor and family needs (practicality and lightness). What I discovered was a wonderful surprise. These filters and the case with which they arrive, are not only practical but, they are also of good workmanship, have a good optical rendering and do not have chromatic aberrations. For me they represent a real REVOLUTION and now I explain why...

Game changer!
I've wanted to try
these K&F Concept Magnetic Filters since they were announced. I'm
glad I bought these. They are great, super easy to use and swap out in
the field. Simply attach the magnetic ring to your lens and then it's
easy to attach and swap out the filters easily. No hassle of having to
screw the filters on and off, this is totally a game changer in my
opinion, I own a bit of K&F gear and these are great quality as
always, I have the k&f square filter kits, but that's a lot easier,
the included case is really nice too, they're not cheap but you get what
you pay for, I'm very happy overall

K&F magnetic filters - CPL, UV, ND1000 - Excellent choice!
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.

No, the screwing UV

Hello! If you use the
magnetic UV filter separately, or use the magnetic adapter ring
together with the CPL filter, you can use a normal lens hood on it. Does
not require a larger thread.
If you use the magnetic adapter ring together with the ND1000 filter,
you cannot use another lens hood on it.

A
We installed it on
our Canon RF 24-105 lens and it was possible to use the lens hood on
this lens because the lens hood attaches to the lens via the bayonette
mount which is on the outside of the lens diameter and the magnetic
filter adapter screws into the thread on the inside of the lens.

No, the ND filter in
the magnetic set is an ND1000 (extends the shutter speed by a factor of
1000). However, it would be technically difficult to construct a
magnetic, yet adjustable ND filter.
