It's true that I misread, or wanted to believe too strongly that the magnetic KF cap was included, well no. At the price of the item, I believed that,,, well no. At €25 per end and after already buying 2 filters from KF, I will do without the cap. Too bad, rather than providing a ring if it duplicates the UV filter (which makes a magnetic adapter, I would have preferred a cap! KF , an opinion? A small discount voucher for my cap?? Otherwise the storage pouch is very well thought out, the lenses are very good, on A4r IV + obj 28/75 2.8 vignetting absent up to 28mm. The hygrophobic coating is great !This is not my first KF product, and generally the quality/price ratio is excellent.

This magnetic lens filter kit is great for quick access to helpful filters. Simply screw on the magnetic ring to the lens and the filters will stick to the ring.The MCUV was clear and clean, the polarizer proved useful for reflections when shooting on location, and the ND filter was great on bright days to help keep exposure in check. Be aware that the ND filter is quite intense, which is great for sunny days but sometimes too dark for overcast or evening shoots on certain settings.You can easily clip the bag to a camera bag or belt when shooting light.

Color-neutral, very easy to use, a significant advance compared to screw-in filters or the large 100x150 insert filters. The included bag is excellent, practical, and fits anywhere. The polarizer seems better in terms of color neutrality than expensive branded products from Nisi. The filters fit onto the holder of the Kase filters without any problems. So far I don't see any difference in the pictures. Unfortunately there was no round graduated filter at K&F

The filters are of excellent quality, leaving the adapter ring mounted, when needed they can be inserted in a second. The filter case is also excellent. I will also purchase the ND64 filter not present in the kit, but I am waiting for a discount.

As a photographer, I use filters, but it's not always easy to put on or take off depending on the situation. But with this system, it becomes so simple that it's almost instantaneous. The product is of very good construction quality and it comes with a very well-made 4-pocket pouch that is resistant to possible knocks. It can be attached to the belt using a Velcro strap. The kit is made up of two screw-in rings, one UV and one empty on which the CPL filter or the ND1000 can be attached. I really 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 nothing short of astonishing. Here are the renderings with the CPL filter on the left and the CPL + ND 1000 on the right. With the filters, there is no loss of sharpness, and color drift is almost zero. The CPL filter polarizes perfectly and the ND 1000 filter is very astonishing in its performance, it is very fine which limits vignetting, a plus. When using the two together, it is better to avoid ultra wide angle focal lengths, but from 16mm, no problem, they can be added together. In addition, they are compatible with my sun visor, I was able to put them on and take them off without having to remove it very easily because the magnetic force is perfectly balanced. Really very satisfied with this first outing, I hope that others Intermediate magnetic filters with this system will be released soon to complete the offer. If there were magnetic lens caps, that would be great. It's a very good investment and the price is more than fair given the quality and results obtained .

Have bought me in addition to square filters now also the inexpensive magnetic filter holder set. I can only say: top. However, I miss the possibility of getting ND 8 and ND 64 (magnetic), because only ND 1000 and polarizing filters are available. A second glass-filled filter holder is included, which can be kept permanently with an adapter ring for a second lens size and still! fits into the super handy case. For the time being, this inexpensive set with magnetic holder is enough for me; if I have further requirements, I will probably switch to the "big" filter holder system from another manufacturer (approx. 400 euros with three ND filters). Which photographer doesn't know this "want to have?". In short: Riko Best's contribution on YT convinced me. Would I recommend it? Yes, to anyone who wants to work with grey filters now and then.

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.

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.
