82mm Magnetic Filter Kit CPL + ND2-32 + Black Mist 1/4 Filter Set + Magnetic Adapter Ring & Lens Cap,28-Layer Coated HD Optical Glass for Camera Lens - Nano-X Series (Compatible with 86mm magnetic cap)

K&F for the win! I’ve owned a few K&F filters and accessories, and they’ve always delivered solid quality without breaking the bank. This kit is a little pricier, but honestly, the value you get makes it well worth it.

First off, the case deserves its own spotlight. It feels super premium...soft padding inside, dividers to keep everything organized, and a smooth zipper with a magnetic flap for extra protection. I also love the little details: the loop for clipping it on and the Velcro belt loop so you can keep your filters handy for quick swaps.

Setup is simple: thread on the base magnetic ring, and from there you can snap on the CPL, VND, or black diffusion filter. You can even stack them in any combo you want. The magnetic system is a game-changer, for swapping filters.. literally takes a second with no threading struggles; just pop one off and click the next one on.

The filters themselves are solidly built from lightweight metal. They feel durable enough to survive a drop or two and don’t add unnecessary weight. Image quality is clean too, with no artifacts and no weird color shifts. The CPL and VND are smooth and give crisp results, while the black diffusion adds a nice cinematic glow. Bonus points for the magnetic lens cap that sticks right on. My only small gripe? It would’ve been nice to have a back cap included, but it’s not a dealbreaker.

Overall, this kit is compact, easy to use, and makes shooting way less of a hassle. Whether you’re a pro or just love creating, this setup is a smart pickup. K&F nailed it again with a product that’s both practical and high-quality.

Got this filter set for my R6 to use for a variety of things. First off, I lost my lens cap a long time ago and have been wanting to try a magnetic one for a long while. Fortunately, one of the options in this kit IS a lens cap, which is super convenient.

I run a 35mm prime lens for like 80% of the stuff I shoot, and so I already had a lens ring adapter that I used for my VND filter, so slapping that on, and then screwing in the base magnetic mount, I was able to easily get a lens cap!

A far as the quality of everything, it is all top tier. K&F is generally pretty respected in this space, and all of the lens kits are of high quality. The threads are smooth, motions are smooth, and the magnetic fitment between the lenses is really nice. I would say with a lens stack up like this, you are definitely more likely to get dust stuck between the outer filter and your real lens, but nothing a blower can't fix.

The image quality coming out of these is great, as you'd expect and hope for filters at this price, so I was happy with that. I don't think I'll use the black diffusion filter much, but both the CPL and the ND filter are quite useful. I'm happy to see they did not include a useless UV filter, like some other kits, and instead have a set of very useful filters. Granted, the ND32 isn't a lot of light filtering, but it can be helpful if you just need a slight tweak to get your frame rate or aperture right.

Overall, its very expensive, but I really like the kit, and it comes with a really nice organizer for them. Lens cap is awesome, and the magnets make me never want to go back to threaded filters again.

I taught photography for a number of years, so this is not my first time out with ND (Neutral Density) filters. These filters are high quality photo equipment that is easy to use. The system is a little different, in that they are magnetic vs pure screw-on. The look is distinctive.

There are two filters in the kit. There is a an open screw-on ring to which the magnetic filters attach. There is a lens cap, and a storage pouch with separate, padded, compartments.

The filters appear to be good quality. The metal rings are not particularly heavy, but feel sturdy enough to support the filter.

In reviewing photos, there are no filter artifacts in the photos caused by the filters.

I like the quick change/magnetic feature of this system. I would buy more filters of this style because it saves time, and the filters are sufficiently secure. Also, the snap together feature means I do not risk getting my fingers on the glass and making a print.

One thing to note is that the open, no glass, ring screws on first. The magnetic filter snaps to that. When using this system, other filters need to be the same system if added to the camera lens past the ND filter, or else they need to be screwed. in first and the magnetic filters attached next. For instance, if using a polarizing filter in addition to the ND, the polaroid would be attached first.

This is a system I really like, and a brand that appears to produce very good quality.

Another thing to note: There are no how-to-use-an-ND-filter instructions. But ND (Neutral Density) is easy.

It works like sunglasses for a camera by reducing the amount of light the camera receives.

The slide ring on the ND 2-32 ring? You spin that and the depth of the darkness changes, altering your f-stop without requiring a change of aperture. Like being able to use a wide aperture or low f-stop in brighter light than usual.
So then the camera has a shallower depth of field = more bokeh in more environments if that’s what you need to blur or soften out a background.

As a professional video producer, I like to have tools that are durable, practical, and save space in my camera bag. This K&F set was just what I was looking for. Mine is for my 82mm Sigma Art 24-70 lens, which is my primary documentary lens.

You get:
- A screw-on magnetic filter holder. Attach this to your lens, and the other pieces magnetically snap into place without threading.
- A combination ND and polarizing filter. You can use the attached screw to lock the polarizer into position once you've spun it to where you want it, leaving the ND portion free to spin and adjust. When I'm shooting outside I like to keep my aperture, shutter speed and ISO locked, and adjust exposure with the variable ND filter. So the combo ND/polarizer filter is the way to go.
- a 1/4 black diffusion, great for a subtle softening effect for interviews
- a magnetic lens cap. I like this so I don't have to remove the magnetic filter holder to replace my stock lens cap. The K&F cap is metal and feels very secure and protective. It's also quite thin, which is a bonus.
- a well-designed carrying case with individual soft pockets for each piece, with a secure zipper and a magnetic flap. If you're like me and leave the mounting ring and the lens cap on your lens most of the time, you might not need this larger case and can downsize to one or two smaller cases to save space.

If you are experienced with filters of this type, as I am, you'll be fine. Otherwise you'll have to do a little research on proper use. There is no documentation regarding how to use a variable ND in the kit, just a great set of filters. Even the box doesn't really tell you anything. But as with most things in photography, a little personal experience is probably the best teacher.

K&F Concept makes solid gear, and I’ve used a few of their more budget-friendly filters before. This new Nano-X series definitely feels like a step up in quality.

The kit comes with a premium case (holds four filters), a CPL + VND 2–32, a 1/4 black diffusion filter, a magnetic base ring, and a magnetic lens cap. Just note that only two of these are actual filters — the other pieces are for mounting and protection.

This is my first fully magnetic filter set, and I’m impressed with how secure the magnets are. The filters themselves feel heavy and well-made, with no cheapness to them at all. The CPL/VND combo works great and saves me from stacking, and the 1/4 black diffusion strength feels perfect — subtle, but noticeable enough to soften highlights without overdoing it.

At around $125, it’s definitely on the pricier side, but the convenience, build quality, and the premium case make it worth it if you use these types of filters regularly. For me, the magnetic system is the biggest win — swapping filters on location is way faster and smoother than screwing them on and off.

Overall, this is a high-quality kit that feels premium in every way. If you need a solid CPL/VND and diffusion filter setup with the bonus of magnetic speed, it’s well worth a look.

This filter set is nicely made and machined. It feels good to hold and doesn't feel cheap or low quality.
It has a main magnetic ring that mounts on the camera lens, a circular polarizer + ND filter, a 1/4 black diffuser, and a magnetic lens cap. It all fits nicely in a handy carrying case that also protect the filters in their own individual slots.
It's all easy to use, mounts smoothly, clips to each other securely and well, and is quite handy if you need those filters.
The circular polarizer turns smoothly and darkens/ lightens depending on how you turn it. It is well dampened and won't turn on its own. The filters can be stacked to create different effects. They all click together well and are just the right amount of difficult to pull apart- they won't fall off on their own.
Pretty handy set, price is high but you do get several filters and if they're useful then this is a good value set.

The K&F filters come in a practical waterproof case for storage and transport. Thanks to the magnetic adapter ring, the filters are very easy to attach and remove. A matching lens cap is included so the adapter ring doesn't have to be unscrewed every time. This is also the only drawback: when the adapter ring is screwed on, the lens's original lens hood and cap no longer fit. If you don't use the lens hood, this isn't a problem. The filters themselves make a high-quality impression and can improve image quality. For normal use and lens protection, the CPL filter should suffice. Further tests with the various filters stacked on top of each other are unfortunately still pending. However, they definitely deserve all five stars.

As a bit of a self confessed camera guy, I’m always trying to make my shoots easier without compromising quality, and this lens kit has been a proper help. I’ve been using it for a few weeks on both outdoor and indoor shoots, and it’s definitely made switching filters much quicker and less fiddly.

The first thing that stood out was the magnetic system. Honestly, it’s a little satisfying when the filters click into place. No more screwing filters on and off while I’m juggling a camera and tripod. I was on a quick outdoor shoot last weekend, hopping between different angles and lighting, and being able to just pop the filter on or off in a couple of seconds saved me so much time.

The kit comes with three filters: a CPL, an ND, and a black diffusion filter. For anyone who might just be starting out and not too familiar, the CPL reduces reflections and glare from surfaces like water or glass, and it really makes colours pop. I used it on a landscape shoot by a lake, and the sky looked richer while the glare off the water was gone — it actually made the shot look like something out of a magazine.

The ND filter is great for shooting in bright sunlight. Basically, it blocks some light so I can still get that nice cinematic blur or shallow depth of field without everything getting overexposed. On a sunny afternoon shoot, I kept it on my lens most of the time — it made a noticeable difference and saved me from fiddling with shutter speeds constantly.

The black diffusion filter has been surprisingly useful too. I used it for a quick interview setup indoors, and it softened the highlights in a way that made everything look more polished. It’s subtle, but it gives your footage a cinematic touch that you notice without feeling overdone.

Build quality is solid. The filters feel sturdy without adding weight to my lens, and the slim frames make them easy to carry around. I’ve thrown them in my bag a couple of times without worrying about scratches, and they’ve survived just fine. Optical clarity is excellent too — no weird colour casts or vignetting on most lenses.

That said, there are a couple of really minor things. On longer focal lengths, the ND filter can be a touch soft. I only noticed it when I was zoomed in a lot, so it’s not a dealbreaker for me, but it’s worth keeping in mind. Also, the magnetic mount means my regular lens cap doesn’t fit unless I remove it, which can be a tiny pain when I’m rushing between shots.

Even with those little quirks, this filter kit has made my life on shoots much easier. Switching between filters is fast, the case keeps everything organised, and I’ve been able to adapt to changing light conditions without slowing down. I’ve already used it on several trips and small shoots, and I can see it becoming a permanent part of my kit.

Overall, I’d still recommend it. It’s convenient, versatile, and really improves footage without much extra effort. The minor softness on some ND filters and the lens cap issue mean it’s not perfect, but for the price and how much easier it makes shooting, it’s a solid kit.

I hope this review helps someone out.

Better quality than the standard K&F. Magnet is quick, thin enough for all of them on with no vignette. The black mist is a little hard to see in that strength if you have the CPL/ND on, but it’s pretty good without. ND is much nicer than the cheaper one without the little lever/lock mechanism. Only complaint with magnet design in general is that adjusting the ND spins the whole thing unless you hold it still. Lens cap is awesome, but same deal. Pulls all the filters with it if you don’t hold it in place. There’s a time and place for the magnet vs screw in if you have both basically. Great for hot swapping and the pouch is awesome. Definitely recommend, but the functionality could be a bit smoother. Works as advertised and good for the price though.

Having used and been annoyed by screw-on filters for years, I was excited to try this magnetic filter system by K&F. I'm kind of a fan of their products, they often seem to find the right balance between quality components and yet still being a good value.

I came back to edit this review because initially I found myself disappointed in the design of the circular polarizer/variable neutral density filter. The way they arrived in the box, the ND filter was stacked under the circular polarizer. Turning one would force the other to turn and both filters could easily be bumped off of the lens.

Reversing these, which is how they are supposed to be, means the CPL goes directly on the lens/magnetic adapter, and next the ND. Yes, the CPL and the ND filters can be separated. You can adjust the CPL to where you need it, and then there is a small tightening knob to prevent if from turning. There is a groove on the CPL where the ND magnetically sits, keeping it secure, and also creating hard stops when you turn the ND from minimum to maximum. This way, both filters stay magnetically secure, the CPL stays put where you've adjusted it, and the ND filter can easily be adjusted as needed. It works very well.
There is some other good news, the magnetic lens cap and the black mist filter do seem to hang on tight to the magnetic adapter ring.

The included case is nice, holds all the included filters, has a bright orange interior so you can actually see what's inside.
The filters have a bright orange band and clear lettering to let you know which one is which.

If there are any criticisms, I do kind of wish there was a simple clear magnetic UV filter included as well, for the other 95% of the time l'm not using a filter for general photos. I also wish that the magnetic adapter ring had front threads so that a regular screw on filter could be used when not using the magnetic filters. I would also like that the different filters were colored differently, rather than all being orange, to make it easier to identify which is which more easily when looking in a camera bag or the filter case. I also don't like that the adapter ring is a bit larger than the 67mm threads; the ring is a bit larger in diameter than the lens diameter. It screws in properly, but it looks a little wonky, That's being nit picky though.

I don't see any obvious color cast with any of the filters but I didn't test them scientifically. If it is there, it is not obvious to my eyes. I also have not had the opportunity to test the variable ND on a wide-angle lens, so I can't comment on vignetting or if any cross pattern is generated with the variable ND. I will come back to edit this review once I have had a chance to test on a wide angle lens.

As far as value, these are well-designed, good quality filters, so the value is there. This can be a starter set for adding additional magnetic filters from their line.
