This is a kit,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, UV Filter+CPL+ND1000

Comes in a padded case with a reverse zip to prevent any water from getting inside in case of rain. It can be clipped on the belt or anywhere else for comfortable use or transport.

As far as image quality is concerned I have few complaints, I haven't noticed any loss of sharpness or colour cast. I have been able to use both the UV+CPL+ND1000 up to 12mm on my APSC camera without vignetting.

INTROI bought 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 with me that would adapt to my new outdoor philosophy and family needs (practicality and lightness). What I discovered was a wonderful surprise. These filters and the case they come with are not only practical but are also well made, have good optical performance and do not present chromatic aberrations. For me they represent a real REVOLUTION and now I'll explain why...[

Generally speaking, I've become a fan of K&F's filters. They are, and this kit is no exception, competitively priced quality filters.But this "kit" is a bit disappointing and, in hindsight, I guess I would have preferred to just buy the 3 individual filters.On the plus side is the obvious: being able to swap among the three included filters is quick and easy. Attaching the filter adapter is simple, and selecting the filter (or choosing no filter) really does take just a second or two.But here are some negatives to think about before you choose this kit over individual filter purchase:- The UV filter does not attach as strongly as the other filters. It sloshes around a bit within the adapter ring, and I'm actually a bit worried that a slight bump could cause it to pop out. By contrast, the ND and CPL filters attach much more firmly. (In case it matters, I'm using the 77mm size.)- The filters are "stackable", allowing for some creative possibiliities, but not entirely so. For example, the CPL filter can be seated firmly inside the UV filter, but not the other way around. So, your one or two seconds of switching/stacking filters may be a little clumsier than needed. It would have been nice if this kit had uniformly designed filter rings, so that all of them worked the same way.- It would have made so much sense if the adapter ring were also threaded so that I could screw on other non-kit filters. That seems like a missed opportnity on K&F's part. In other words, if I want to take one of my traditional 77mm filters, it would be nice if it could simply screw it onto the adapter ring. But instead, I have to unscrew the adapter ring to make way for my old filters. Perhaps this is K&F's way of nudging me to consider buying more of their magnetic filters to add to my kit.So, in short: the individual filters, as far as filters go, are great. But this kit has plenty of room for improvement.

Great product but when you buy a single filter you get a lens cap with it but you do not when you buy the entire set.

There is nothing to dislike about these filters. The Magnetic Feature just makes it so easy to go from filter to filter as needed. It works exactly as a photographer would expect them to and works as advertised on the Amazon Website. Please note that the mounting ring has to be removed to reverse the lens hood for storage (it will fit in the normal use direction with the ring on), and the lens standard cap will not fit. But in reality, this should not be a problem for the seasoned photographer who knows how to stow the lens components.

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).

The included pouch is well made and easy to use. If you buy kits in multiple sizes you can even combine them into one pouch by storing the filters magnetically stacked and assigning each compartment of one pouch to a different diameter.

I love that this set includes UV, polarizing and ND filters all in one set. Comes with a storage pack. Very easy to attach. I love the magnetic attachment. This is so much easier than screwing on each filter. After having another brand and type of filter getting stuck on my lens, this was a welcomed change. Great innovation. Great glass quality.

Amazing quality product. The filters fit perfectly. They don't fall off even with the weight of the lens cap on them. I didn't use the adapter ring. I put the UV filter onto my lens as an everyday filter and lens protector. I then just put the polarising filter over it when I need it. The filter fits perfectly. Even with the two filters stacked I have no problems putting the lens hood on. There is also no vignette with my 24-70mm Nikon lens. I'm very happy with this filter system. Innovative!

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.

As a landscape photographer, I found this filter system really interesting. Unlike screw filters, these filters are applied and removed in a fraction of a second, while unlike plate filters they are much less bulky, lighter and, obviously, much quicker to install. PACKAGING AND ATTENTION TO DETAILS Filters are delivered inside a comfortable and really well made case with four compartments. The case, in the back, has a hook and loop buckle that we can use to attach it to our tripod or to our trousers and, also, a metal ring so that it can be attached to our backpack, to the tripod column or wherever we prefer. Finally, the zip closure of the case is proof against rain or water infiltration. The filters are contained and protected individually within special sachets to avoid any potential damage. CONSTRUCTION These magnetic filters from the Nano Series by K&F Concept are made of optical glass perfectly resistant to water, oil and dust. The external frame is made of slightly knurled aluminum to allow an excellent grip. They are extremely thin and, even by mounting all three filters at the same time (UV, CPL and ND1000), the thickness is extremely limited. UV FILTER In the photographs I took with the UV filter there are no color alterations, no loss of sharpness and details and no casts of any kind.POLARIZING FILTERThis polarizing filter provides a pleasant overall contrast to the image, increasing the contrast between the individual colors and saturating them without exaggerating. Furthermore, it provides a very slight warm cast which, personally, I don't mind but which is easily correctable in post-production.ND1000 FILTERThe first thing that strikes you when using this ND filter is that it produces a slight - but present - warm cast. Personally I think it is not a problem as it can be removed with one click in post-production. Finally, the overall sharpness as well as the details of the image are not altered. CPL + ND1000 FILTER. I consider the CPL + ND1000 combination very interesting. In fact, the polarization effect reduces the warm cast of the ND1000 filter and also provides a pleasant saturation and a soft contrast overall and between the colors of the final image. In terms of sharpness and details, there are no significant deteriorations. However, there is a slight vignetting. PRACTICALITY The K&F Concept Nano Series magnetic filter kit is truly extremely practical. The case that contains the filters has compact dimensions, 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 go on long excursions where the weight of the equipment, after several hours, it starts to make itself felt. The installation and removal of the filters is nothing short of lightning-fast; in a matter of seconds you can easily mount all three filters and, in just as many seconds, they can be removed. The hold of the magnets is really good and therefore there is no fear of finding yourself with filters that fall during the installation phase. shutter or transport. TO WHOM IT IS RECOMMENDED In conclusion, I would strongly recommend this filter kit with an excellent quality/price ratio to: - those looking for a first filter kit to start experimenting with creativity; - those looking for an excellent value between quality, size and weight; - those looking for maximum convenience when shooting and composing.
