really like the concept of this filter set. I'm not the most coordinated person and switching filters on the spot requires some coordination, so I just used a single filter - and it shows up in my photos. I really like that this set really requires very little coordination. I was able to quickly and easily change filters when the lighting changed. The set comes in a nice padded fabric case with individual pockets and a Velcro strap for attaching to a belt. The set contains three magnetic filters and an adapter ring. The lightest filter is a UV filter that looks completely clear. Like the adapter ring, this filter is threaded. It is the only filter that is threaded and is also the only filter that appears a bit loose when attaching the adapter. The other filters fit much better but fit the UV filter just as well, so I decided to skip the adapter ring and just thread the UV filter onto my lens and attach the other filters to it. It obviously means an extra layer of glass when set up this way. Anyway, I like this set and would recommend it.

These are so easy to use and the quality is fantastic - both the build quality and the picture quality. I can't see any colour cast whatsoever from both the CPL & ND filter. I think you would really need to pixel peep to see any sharpness difference, and even then I'm not sure there is.Being able to attach the filters to both the UV filter and filter ring is really clever - I keep the UV on my 24-70 F4 and the filter thread ring on 16-35 F4 so it makes it even faster to clip on the filters no matter what lens I use.Since the ND isn't variable, there's no dark X. And no vignetting at 16mm, unlike when I use my square filter set.The downsides that I see at the moment:- You can't replace the filter thread on its own, so if you break or lose it, you have to buy a new set. I contacted support but was asked to pay $16 for delivery of a new thread....- The range of NDs isn't as big as a square filter system (yet) and again I'm not sure if you can buy them as singles or whether it's just part of these kits

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.

The magnetic attraction of the MRC UV filter (72mm) leaves a lot to be desired! The filter wobbles around on the adapter ring and threatens to fall off every time the camera moves, so it is not safe from loss when used outdoors. The other two filters have a solid hold on the adapter ring.

Sure the price is high, but they are very comfortable

own some K&F Concept Products. They offer quality products without the high price that we are used to in the world of photography. Let's talk about the filters individually first. All 3 filters are of the highest quality, at least at this price point/level, as we have come to expect from K&F Concept products: - The CPL filter has no color shift and works as expected. -Same for the ND1000, although I don't often use 10-stop filters during my testing (my most used filter is a VND Nano from K&F Concept) it worked well, no cross present even when step-up -Rings were used. -The UV filter has no color shift and the main purpose of the UV filter nowadays is to protect the lens surface BUT where this kit has VERY MINOR problem: The magnetic ring holder. The magnetic ring holder works great with the ND and the CPL, just not so well with the UV filter, but it is by no means bad or I would call it unsafe, at least not on the 82mm filter size version, your mileage may vary Size of the kit will vary as the magnetic finish may be different on your version, only the grip doesn't feel as tight as the other two filters and there is a SMALL bit of play but not enough to justify a star over it lost, I mean if you shake the camera with full force you might drop them, but with regular use I don't see them just falling off the ring holder. As a sum of all parts I would say this was almost perfect. This kit complements my VND ND2-400 and includes everything I need to cover all my filters along my step up rings. The UV filter thing doesn't make it lose a star but maybe half so I'd say 4.5 but since there's no option for that if I had to choose between 4 or 5 stars I'll go with 5.

I shoot in various elements and destinations where the lighting is different and filters are needed to achieve optimal results. I use the traditional screw-on filters but find it very time consuming especially the way it has to be perfectly aligned with your lens which takes up to a few minutes for each one when I could miss the opportunity of my shot. I find this set of K&F filters to be a great choice for me. I am by no means a professional and I take pictures for fun with my Nikon D850 and these filters have worked great for me. The magnetic adapter ring is easy to screw onto the lens and the lenses stick to it well. These glasses work great in the rain and are not only waterproof, but also water beading. I had no problems with fogging between the lens and the filter. They are packaged in a hard case, each in its own slot. I find this to be excellent value for all the different lenses offered in this set and I am extremely happy with it.

really like the convenience of this magnetic filter system. All you have to do is thread onto the base ring and magnets do the rest. Makes it less likely to damage your lens' threads if you don't have to put on and remove a filter every time you need to use it. I use this with a full frame 24-105mm lens and the base ring works with the lens cap and hood, although you'll probably have to remove the hood to snap the filter or your fingers will get in the way. Each of the filters themselves are slightly heavier than the bolt on K&F versions, probably because they have to make the filter ring out of a magnetic steel instead of aluminium. Whatever the reason, they feel a lot more premium than the regular K&F version. In terms of performance, it's a bit of a mixed bag. I don't have tremendous experience with CPL and ND filters (this is my first set) so I don't know what would be considered good performance in a given price range. Let's start with the ND: it seems close if not a full 10 stops, which is great; the previous K&F screw 10 stop ND which I returned with only about 8 stops in practice. The ND has a noticeable color cast (see: in-camera photos of the sea). The ND image that brought the raw files into Lightroom had 26 more dots of magenta tint and was 1000K warmer than the unfiltered image. This cast was relatively easy to correct, although the colors weren't exactly the same. Less correctable was the 24mm vignette, which needs to be cropped out. With my lens at least, a quick crop test indicated I lose about 1mm of focal length to the vignette. Note that because the filter is magnetic, there is a small amount of float between the filter and the lens, so the vignette is not always symmetrical or consistent from use to next. In aggregate, the CPL filter (photos looking out the window) has a similar vignette to the ND filter at 24mm, but seems to reduce some reflections in my windows. Not much for me to point out ours here, it seems to do the job. The set comes with a UV filter, but I don't plan on using it unless I'm in a rainy/dusty environment where my lens needs a bit more protection, so I haven't tested it yet. For both the ND and CPL filters, I didn't notice any noticeable decrease in sharpness caused by using the filters. However, due to the burst of color with the ND filter, I recommend either shooting in RAW or setting your white balance before putting on the filter. For the price ($110), I think the performance of these filters is acceptable. I'm a little disappointed with the vignette, but I've heard of much more expensive filters that have similar issues, so I don't want to be too harsh on this set. All in all, for someone like me who does this for fun, I think it's a great system to learn the basics until I can justify upgrading to something premium. If you're a pro and making money from your photos, then maybe look into something more upscale like Freewell, or invest the time to create a preset to fix the color cast.

I am absolutely satisfied with the overall package price performance is definitely right here the magnet is sufficiently strong, the bag offers good protection and can be fastened well with the double Velcro fastener and the eyelet for a hook I would buy the magnetic filter set again at any time

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!
