There really isn't much to say. Very clear purchase recommendation. Great pictures, great value for money.

Not try yet! But I will give my opinion on the articles later!

I already own a backpack and an adapter for my Fuji XT-3 from this brand and have not been disappointed once. The adapter fitted perfectly and so did these ND filters here. My buddy and I are getting a little into the image film area at the moment and are trying out a lot in that regard. So far, we always had the problem with the Fuji that the sky was totally overexposed and I had to adjust the aperture. This problem is now off the table.

In a nutshell about the product itself: the supplied bag is great and by no means just a cheap prop, but a high-quality and sensible storage option for the filters. The filters themselves are of very high quality, fit my Fujinon XF 18-55 very precisely and do exactly what they are supposed to do without any compromises.

That pictures say more than 1000 words, even if it may sound trite, I've attached a small sequence from our last shoot, where you can finally see the sky. In this case only the ND8. A lot more should be possible with the ND64, even on very bright days. The price-performance ratio is clearly great here. My recommendation!

I ordered this filter for my Nikon lens. I must say I am satisfied, the filter fits wonderfully and I have not noticed so far that there are any edges.

I like how they are easy to use and saves me time and frustration from having to switch lenses.I do wish that I could use my K&F 150x100 square filter holder with this kit.It’s unfortunate that K&F did not create this kit with the thought of using it with the square filter kit though.I do use a UV and CPL circular filter with my square filter system at times and not to be able to connect my K&F 82mm filter holder ring with this is a bummer.I’m surprised it doesn’t work with it or that it’s not able to screw onto the magnet filters in this kit.K&F please fix that in the future.

Love it. First ND1000. Now I can work on my skills

I am very pleased with this system and the quality of the filter lenses. It is wonderful for very quick changing of filters. Unfortunately I accidentally lost the ND filter the first time I went out and did not realise it until I was back home. My friend had zipped the bag they come in, and I, thinking it was still open and more concentrated on trying the one on the camera. unzipped it. So during my wanderings, the ND fell out. I did eventually manage to replace it, and received a magnetic lens protective cover as part of the order. I am made up now. I do recommend this system and it has the filters that I use, perfect.

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.

The filter is packed in a practical box to protect it during transport. And this filter works very well.

For the price of one, I now have a well-made variable ND filter for all of my lenses - I'm very happy!
