I always get nervous with very expensive things adhered with just magnets, but so far I've had absolutely no issues with these filters staying put on my Canon RF70-200mm. They get knocked around quite a bit in my bags or during lens swaps, and I haven't had any come dislodged in any meaningful way.
They're expensive, probably too expensive for my taste, but they're good filters and it is handy to be able to swap them out quickly. I haven't noticed any issues with image quality, which is the very least you could hope to say at this price point for this glass.

I ABSOLUTELY LOVE this filter set! It is high quality, works really well, and is also very good looking.
Pros:
- The quality of the filters is very good
- The magnets are very strong. I don't worry at all about the filters falling off of each other
- Adding and removing any of the filters is extremely easy, especially when you compare it to the traditional screw on method
- Despite all of the filters in the kit being magnetic, they also include regular filter threads so these can still be used in conjunction with normal filters
- The inclusion of a magnetic lens cap is a really nice touch
- The carrying case that these come in is well built, well designed, and includes a belt loop so you can easily carry these filters with you
Cons:
- The price will likely be a bit high for a lot of people. Do I think it is good value for money? Definitely. But $160 is still a good chunk of change
- The orange color accents might be a turn off for some

This was really nice to use. Had a little bit of vignetting though, not sure how that could happen because the filters themselves are wider than the barrel due to the magnetic adapter. good news is i think they add to the types of images and videos i capture, though i kinda want the option to do that in editing instead of baking it into the image and living with it. you can kind of correct it the other way in post too, and honestly it's really not that bad. could be my lens too. I did have some struggles with changing my CPL because it's stiff enough to start unscrewing the threads. I didn't notice any X patterns or anything like that, so i think it's pretty good. The lens cap is aluminum, and you have to use it when you use these. I love kf cases too, they're always made of cool materials, and they fold up super small to fit anywhere.

Canon introduced a new mounting system with the release of their Mirrorless cameras. However, this didn't make all those expensive lenses you already had obsolete - they just need an adapter.
A neat feature of these adapters is the ability to "slide" a filter in between the back of the lens and the sensor. Seems easier to carry, and most importantly you don't need to switch filters onto different lenses... as long as they are using the old mount.
Well when you get some of the new mount lenses in your collection, you run into a problem: those drop-in filters don't work with the new lenses. So now what?
This magnetic system provides the versatility of a drop in filter, but works on ALL your lenses. The magnetic attachment points are strong: there is no fear anything is going do fall off, regardless of your shooting angle. And it is incredibly easy to swap filters - easier than those drop ins. And, unlike the drop ins, you don't need to expose your sense to the open air- everything stays sealed up and protected.
Depending on the lenses you use, it is possible to use these same filters on different diameters. If you have some 82mm and some 77mm - just but a step-up ring and you are good to go.
Aside from.the functionality and ease of access, the filters themselves are phenomenal. From the clarity of the images you get through this glass, to the robust and smooth feeling of the rotation mechanism, these do not disappoint.
And you get all this for cheaper than a single Canon drop-in kit.
These are really nice, and they can bring efficiency to your workflow: no more screwing and unscrewing threads to get the perfect shot- just snap a different filter on!

I'm always impressed with the quality of K&F, and this is no different. These lens filters are made to the highest standards and tolerances, fit perfectly, and make for amazing photography. Comes with a high-quality case for portability. I trust this brand and they don't disappoint. This is no different.

This is a great filter kit for anyone doing portraits or people video. The CPL, ND, and black mist filters are all quick to swap out thanks to the magnents and the quality of the filters is pretty solid. I haven't noticed a detriment to my image sharpness with these but I also am not using them on a high megapixel count camera (20-24MP for me). The best two parts are the case that these come in - it opens like an accordion file making it super easy to find and grab your filter and the lens cap meaning I can leave my magnetic attachment on all the time and still have the benefits a lens cap offers when my lens isn't in use.
Nitpicks are that the ND filter requires screwing on which isn't the easiest - I definitely have scratches on the magnet base from not aligning everything just right and trying to screw it on. If you don't get it screwed on just right then the ND filter is a pain to adjust since the magnets attaching the second CPL are strong enough to turn the first CPL when it isn't screwed in.
But for the convenience of quickly adding and removing an ND filters for something like a wedding where you go from outdoor video to dark inside video in minutes make this a fantastic addition to my video kit. Well done K&F!

I’ve already had a 6-9 stop with an nd and polarizer filter, and I should have started with a 1-5 stop instead. Well this basically completes my set for 67mm lenses.
I’ve never had a magnetic set and I’m really loving it. It’s easy to swap in and out, and it’s very secure.
It does come with a storage case that’s both zippered and magnetic. It’s a bit bulky but holds it well and is secured. You can opt to use just the magnetic closure or utilize both the zipper and the magnetic closure to store things. It’s a nice feature should you want to access this on the go.
I’m an amateur photographer at best, but these lenses really rounded out my basic needs for the type of photos that I shoot. And for the price, ease of use, and versatility of this kit, I couldn’t be any happier.

I was looking for a filter system for my camera equipment that wouldn't take up too much time on the go – screw-in filters are simply a hassle in the long run. That's why I ordered the magnetic set from K&F Concept.
My first impression: very clean workmanship, the metal rings seem robust, and the glass is high quality. The adapter stays permanently attached to the lens, and the filters (CPL, ND2–ND32, Black Mist 1/4) can be attached or changed magnetically in seconds. This saves a tremendous amount of time, especially in changing lighting conditions. The CPL filter provides more vibrant colors and reduces reflections, the ND filters reliably extend the exposure time, and the Black Mist gives portraits or highlights that slightly soft, cinematic look.
In use, I noticed that the filters are color-neutral – no distracting color cast, minimal vignetting, and still unobtrusive even at 24mm. Only at very wide focal lengths is there a slight darkening visible at the edges. The magnetic lens cap is also practical, as it protects the glass at the same time.
The included case is compact, sturdy, and has enough space to keep the filters safely separated. The only minor drawback: an ND32 filter isn't always sufficient on sunny days; I would have liked to see more dense filters included in the set.
Overall, though, it's a clever and versatile system – ideal for travel and quick filter changes while filming or photographing. A worthwhile investment for anyone who doesn't want the hassle of constantly screwing filters together.
