Delighted with my 55mm magnetic filter kit. It consists of 4 components, an adapter, a UV filter, a polarizer filter and a ND1000 filter. Both the polarizer and the UV filter are threaded, so they can be screwed on the front of the lens, but they also have a magnetized part, so the rest of the filters can be magnetically attached to them. I have several types of filters, threaded, square and these. Without a doubt, the magnetic ones are my favourite filters, I am very happy with them as they are very comfortable to use, especially for that reason, for the comfort 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's instantaneous to put on or take off any of the others. I always use the UV, which also has a thread on the outside so I can put the cap on, the thread is fine, but the cap stays on and doesn't fall off. This way, I always have the camera ready to attach any of the other filters quickly and easily.

Many voices will say, such cheap filters simply can't reach the quality of a brand filter and also I was someone who would have affirmed this immediately until now, so convinced was I of my B&W, Rodenstock, Haida and Co. filters. But now the surprise: the K&F filters do not show any conspicuities. No unnatural colour shifts, no clear loss of sharpness, hardly any flare or ghosting, 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.

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!

►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

I needed a more travel friendly set of filters to take with me on my hikes that would be too cumbersome to use my square ones. Having these filters in it's own soft pouch was perfect and it didn't take up much room in my camera cube. The magnets were strong as they held on while I was setting up my composition - sometimes in the rain and while on uneven ground.UPDATE 10/26/21: After over a month, I've already lost a CPL filter. Make sure the filter is flush in either the UV adapter or adapter ring. I was busily setting up my camera on a cliffside when I accidentally bumped my tripod and the CPL filter fell off.

Typical of my experience with K&F products, these are excellent filters. They are every bit as good as a couple of other, higher priced, popular and similar products. No color casts, well manufactured, and simply work as described. Save your money and buy these over the more hyped brand names.

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 shoot in various elements and destinations where lighting is different and filters are needed for optimal results. I have been using the traditional screw on filters but I find it time consuming especially how it needs to be aligned perfectly on your lens, taking up to a few minutes for each one when I could miss the opportunity of my shot. I find this K&F filter set to be a great choice for me. I am no professional by any means and take photos for fun with my Nikon d850 and these filters have worked great for me. The magnetic adapter ring is easy to screw on the lens and the lenses stick to it well. These lenses work great in the rain and are not only waterproof but the water beads off of them. I have not had any issue of fogging between the lens and filter.The come packaged nice in a hard case, each in its own slot. I find this to be a great value for all of the different lenses offered in this set and I am extremely happy with them.

This is a solution for one of my pet peeves, taking filters off and on in the field. I always carry a CPL filter with me when doing a shoot, but it is difficult to take them off and on in the back of a Range Rover on the move. This one is protecting my Olympus 300mm f4.0 lens (UV) and allows me to quickly switch to the CPL when I need it. I ordered another set for my 72mm lenses. Great packaging, good carrying case and I'll be able to cover all my field lenses with the two sets. Extremely impressed with the ease of rotating the CPL filter. My lens cap stays on with no problem and can be either on the CPL or the bare magnetic mount. The magnet is very strong, the filters stay where you want them until you want them off.
