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.

They are very easy to use and the quality is fantastic - both build quality and image quality. I don't see any color from the CPL filter and ND filter. I think you'd really need to pixel peep to see any difference in sharpness, and even then I'm not sure there is. Being able to attach the filters to both the UV filter and the filter ring is really smart - I keep the UV on my 24-70 F4 and the filter thread ring on 16-35 F4 which makes the clip even more fast filters, no matter what lens I'm using. Since the ND is non-variable, there is no dark X and no vignetting at 16mm, unlike my set of square filters. The downsides I see so far:

I ordered this lens kit for my husband and it has been very helpful for his outdoor photoshoots. It is easy to install and the magnetic feature surprised us by how well it worked. The lens is water resistant and we haven’t had any scratches on it. This definitely helps out when you’re outdoors working. It also comes with its own case. Highly recommended.

I've had these lens filter kit for a few months now. Unfortunately, the magnetic base ring got warped probably from pressure on my bag. They replaced it without any hassle. I would suggest keeping the base ring in a non-bendable case which is what I will be doing from now on. I would definitely buy from this seller again!

trabajan super bien en mi lente , me enamore de ellos

This concept is revolutionary! The filters are of very good quality, solid, delivered with a very good quality pouch as well. Very easy to use, the ring is screwed onto the lens in 2 seconds and then the filters are magnetized. I have been able to test lots of times and never has a filter come loose! Additionally in this kit there are the 3 main filters and essential to have. I recommend

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.

First I must say that I am a Vine reviewer and I received these B08T24T25S Professional Magnetic Lens Filters Kit free as part of the Vine program. The vine program was dev eloped to generate review of new products. This kit includes A UV filter a Circular Polarizer and a Neutral Density 1000 filter as well as a magnetic adapter ring. It all comes in a nice waterproof zip filter case. This is a really nice system, I remember back in the film days there was soothing similar but not as good as this, it was an adaptor with square filters you slide in and out, it was fine except for vignetting with wider lenses. This system is just as convenient but will have no problems with vignetting. It comes with a very slim ring adaptor and the magnetic filters. You can simply keep the ring adaptor on all the time on your preferred lens. It works really well and you can change filters in seconds. In this set you get a UV for cutting down some haze and for lens protection. A CPL great for scenics, reflections etc., and a ND for long exposures, this one is ten stops. This is a great set, I highly recommend.

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.

The filters work well individually, with no noticeable colour cast on the ND filter and only a slight warming of the image with the CPL. The magnets appear to be strong enough, the CPL rotates smoothly and I wouldn't worry about them falling off.A minor issue is that the pouch hasn't been stitched properly, so it's a little bit deformed on one side. But it's still perfectly usable, and is small enough to fit comfortably in my camera bag.Overall I'm happy with the performance of the filters, but I don't seem to be able to stack the CPL and the ND without a diagonal darkening of the image. This depends on the rotation of the CPL, and it's either from top-left to bottom-right, or top-right to bottom-left. Disappointing, but it's probably rare that I'm stacking the filters.
