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.

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.

I love that this set includes UV, polarizing and ND filters all in one set. Comes with a storage pack. Very easy to attach. I love the magnetic attachment. This is so much easier than screwing on each filter. After having another brand and type of filter getting stuck on my lens, this was a welcomed change. Great innovation. Great glass quality.

Amazing quality product. The filters fit perfectly. They don't fall off even with the weight of the lens cap on them. I didn't use the adapter ring. I put the UV filter onto my lens as an everyday filter and lens protector. I then just put the polarising filter over it when I need it. The filter fits perfectly. Even with the two filters stacked I have no problems putting the lens hood on. There is also no vignette with my 24-70mm Nikon lens. I'm very happy with this filter system. Innovative!

I had been wanting to try a magnetic filter system for a while so I'm glad I got my hands on these. All the magnets work well and it's easy to screw on the adapter onto your lens. I personally only really use the ND filter, but the other 2 filters could stack on no problem and without any degrading in image quality or color.

I was able to look closely at high resolution RAW files of photos I took using the ND filter and they looked extremely clean. The little carrying case is a nice touch as well.

One suggestion is maybe adding a 6 stop ND filter to the set. There were a couple times where the 10 stop was just a little too much light blocking for me.

I would definitely recommend this to most photographers as a great and easy all around filter system

As a landscape photographer, I found this filter system really interesting. Unlike screw filters, these filters can be applied and removed in a fraction of a second, while unlike plate filters they are much less bulky, lighter and, of course, much quicker to install. The K&F Concept Nano Series magnetic filter kit is extremely practical. The case containing the filters is compact in size, which allows us to carry it in our backpacks with very little space sacrificed.
The weight is extremely light, which is really useful for long excursions where the weight of the equipment starts to be felt after several hours.
The installation and removal of the filters is lightning fast, to say the least; in a matter of seconds you can easily fit all three filters and, in just as many seconds, remove them.
The holding power of the magnets is really good and therefore there is no fear of finding yourself with filters that fall during shooting or transport.

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.

If you are looking for good quality filters that don't negatively affect your image and are very easy to carry and use, I would definitely buy magnetic ones. Carrying the square ones is sometimes a nuisance and I find the threaded ones much more uncomfortable, apart from the risk of them falling off, I'm a bit handy and it has already happened to me several times with the threaded ones. With these so far no problem and I'm very happy.

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.
