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.

Typical of my experience with K&F products, these are excellent filters. They are just as good as a few other more expensive, popular and similar products. No color casts, well made and just works as described. Save your money and buy them from the most popular brands.

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 .

I needed a more travel-friendly set of filters to take with me on my hikes that would be too bulky to use my square filters. Having these filters in its own soft pouch was perfect and didn't take up much room in my camera cube. The magnets were strong as they held while I prepared my composition - sometimes in the rain and on uneven ground.

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.

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.
