K&F concept are a really reputable brand and this will be one of many ND filter sets I have purchased and received from them. This specific listing for the Osmo Action 6 with a CPL+ND8+ND16+ND32+ND64+Black Mist 1/4 is something that's blown me away.Each filter is expertly made and feels highly durable and tough. They fit the Osmo Action 6 perfectly. I have no comments on K&F Concept's packaging, although it does look nice so yes it's suitable to be gifted to an Osmo Action 6 owner.K&F Concept, and these items specifically, deliver excellent performance. There's none of that X-shadow that is a mainstay in cheap terrible filters. Rather these filters are made to a high standard clearly have very good quality control, and testament to that quality is the rather high price. However you can be sure that in purchasing these filters you won't have to buy another set for the lifetime of the use of your camera given that you treat them right.Currently the filter set is on offer for £48.32. That works out at just over £8 per filter. Is this set for the use of hobbyists? Yeah. Is it for amateurs? No. Is it suitable for professionals? Absolutely.I think you need a certain level of skill to be able to effectively use the different grades of ND. But again if you want to take that jump and make that rather big investment, I don't think you would regret it. It will level up the outputs of your Osmo and allow you to achieve more cinema-quality footage that the camera is capable of but needs that helping hand in tough outdoor environments.

Always trusted K&F Concept for filters, and these Snap on ones are quality! The optical glass is excellent, very clear, and they do a great job of controlling light without wrecking image quality.These are snap on filters rather than screw on, which for me makes them very easy to take on and off, especially when out riding. I can confirm they fit the DJI Action 6 perfectly. I also tested them on an Action 5 and they are too big, so they are not interchangeable across models.I use an action cam on my motorcycle, and vibration is part of life. On older snap on filters I have had the odd occasion where vibration caused one to come loose, and these feel like a similar fit. It has not happened often, but it is something worth being aware of if you ride regularly on rough roads.In use, they perform brilliantly. I often ride in bright conditions where footage can end up overexposed, and these filters sort that out straight away. ND8 or ND16 covers most UK weather perfectly. ND32 and ND64 are less commonly used for me.They are not cheap, but the build quality and optical performance match the price. For me, they feel like good value for money if you care about image quality and want filters you can rely on.

The very large case, made of a slightly too soft but very well padded, very large case comes with 6 filters, which are ideal basic equipment. With ND strengths of 8 to 64, there is already scope for experiments with long exposure, and various daylight situations are covered anyway. The CPL brings reflections under control, here it is a standalone filter and not combined with another, and it is not for nothing that the Black Mist 1/4 is one of the most popular puzzle pieces on the way to a movie look, with the softness and the beautiful aura around light sources that it creates.
Filters are in a fairly compact and robust case.

Given the number of filters, it would have been nice if the individual slots, in which they sit very securely, had been labelled in the case.

They sit perfectly on the camera and hold, even when using a cage with appropriate openings. Visually, the filters are also of a high level and give no cause for criticism. They all fulfill their purpose and have no noticeable negative side effects. The glasses are flawless, the metal frames are clean and accurate. You have to be careful with filters for action cams with your fingers, the glass is flush with the sockets at the front, there is virtually no room to avoid contact with the glass. But for these cases, there is also a cleaning cloth with

The Black Mist the best, the ND filters also serve their purpose. But even with this set, the desire to be able to combine several filters together remains unanswered.

Otherwise, you get a high-quality all-round carefree package, with which you hardly have to buy any more filters.

£55 at time of review CPL, ND8, ND16, ND32, ND64, ND256I got a DJI Osmo Action 6 a couple of months ago and looking forward to using it snowboarding next month, so ND’s will be essential to cut down the light levels. I’ve given these a quick test, but as the weather is so gloomy here currently my tests have been rather limited, as it’s not been bright enough for me to test anything above ND32 (as that’s 5 stops already), so I’ve tested the others.To CPL works well, and a bit of pop to the image overall and of course cuts out reflections on water and windows, although as soon as you tilt the camera the flections can reappear. The 8 & 16 ND’s worked well cutting down the light levels to keep my shutter speed down, there’s a tiny colour cast, but it’s really small, but noticeable if you’re really pixel peeping or colour correcting in post etc, but if you’re that particular, then you already know how to over come it)Swapping the filters over is simple too as your simply pop them over the top of the lens (you can’t stack these filters), comes with a good case too. All in all great set of filtersHope my review was helpful

I have used the Nano-X black diffusion filters on my Lumix camera and an older DJI Action 4 because it takes the edge off the digital precision of modern sensors and lenses to create a subtly more organic film-like feel.

In terms of effect, it delivers softer halation on highlights for a smoother roll-off, but most importantly without sacrificing shadows or mid-tones and avoids contamination in the bokeh. I am surprised this is not more talked about because they do this better than practically any diffusion filter out there regardless of price.When it comes to this version for the DJI Action 6, it works just as well. The 1/4 is enough to gently finesse the video and create a more natural film-like look. This is especially important for me when I need to insert a clip into a longer piece using the Lumix camera where I want to maintain a consistent cinematic look.The glass has a 28-layer coating, which makes it highly resistant to flare and makes it tough as nails, which is exactly what you want on a camera that can operate in the worst conditions. It has a knurled grip on the sides that makes handling easier, especially when you are cold and wet, then it just snaps into place.In short, these are really high-quality filters that serve a practical purpose, rather than just giving you a foggy look, so you can practically put it on there and forget it. The effect is tangible, yet relatively subtle, which is exactly what I expect from premium-quality filters like the Nano-X range.

A very good quality snap on black diffusion 1/4 lens for dji osmo action 6 camera.I like that the lens comes well protected in a good quality case , it's well protected inside and is compact enough to carry in my camera bag.The lens is a circular lens the size of the dji action camera front lens, it's a quick and easy snap on design, so it can be put on or taken off in seconds when out filming videos.The lens is thin and compact, adds little bulk or weight, I like that it comes with a small cloth to wipe the lens too.It adds a really nice cinematic effect , softens detail and light glare , I think I'll be using it for outdoor videos such as sunrises, sunsets, and nature landscapes but can be used for vlogging and general filming , it's a nice lens to have in my video equipment and works well.

I have reached that stage in my life where my face looks less like a fresh peach and more like a crumpled paper bag that has been through a wash cycle. This K&F CONCEPT black diffusion 1/4 filter is essentially digital Botox for the action camera crowd. I can just snap it on and suddenly I am living in a dreamy 1990s perfume advert rather than a harsh 4K reality. The installation is so simple that I can do it even with my clumsy thumbs. I just press it on and the little anti-slip washer keeps it from flying off into a bush when I am doing something supposedly adventurous.The glass is actually proper high-definition stuff with twenty-eight layers of nano coating, so when I inevitably get my sweaty fingerprints all over it or a bit of sea spray hits the lens it is remarkably easy to wipe clean with the provided tiny-weeny cloth - really, they ought to make these cloths a little more generous. It comes in a sturdy storage box which is brilliant because I usually treat my gear with the same care a toddler gives a cardboard box, ahem!Looking at the results I can see a massive difference. On the unfiltered side of things every stray hair and skin blemish is screaming for attention under the winter sun. Once I apply the filter the highlights get this gorgeous hazy glow. It softens the edges of the world. It is the visual equivalent of a warm hug or a soft-focus dream sequence where I am finally the hero of my own indie flick.The effect is definitely useful if I want that cinematic look without spending hours in an editing suite trying to fake it. Is it too subtle? Not for me. It hits that sweet spot where I look better but people do not immediately ask why I am filming through a layer of Vaseline. It is a specific vibe that it gives to film and photos, and in that respect, if I want to look like a rugged survivalist this might make me look a bit too much like a romantic lead in a Romcom. For vlogging though, and making the harsh sun behave itself, it is a total winner.

I picked these up for my Osmo Action 6 recently because let's be honest, the standard footage can look a bit digital and harsh sometimes. Filming in bright sunlight the shutter speed just goes through the roof, so these correct that. These K&F filters are actually a bit of a lifesaver for getting that proper cinematic look without having to mess around with complicated settings.The snap on design is the best bit for me. When you are out with the family you really do not have time to be screwing things on and off while the kids are getting restless. You just press them on and they stay put. I was a bit worried they might ping off when the camera is getting knocked about, but that anti slip washer does the job perfectly. I have used them with my usual cage and they fit fine, so no issues with compatibility there.You get a decent range in the box. The ND filters are essential for those bright Saturday mornings at the park so you can keep your motion blur looking natural rather than like a choppy home movie. The CPL is great for cutting out the glare on the water when we are at the beach, and the black mist 1/4 is a nice touch for some of the more artistic shots. It softens everything up just enough to make it look like you actually know what you are doing with a camera.For the price, the value is excellent. You get six filters that cover pretty much every lighting situation you will run into. They feel solid, the glass is clear, and they do not add any weird colour casts to the footage. If you want your holiday videos to look a bit more professional without spending a fortune, this set is a bit of a no brainer.

This filter set was used with a DJI Action 6 mainly for outdoor filming in bright daylight, including walking shots and general travel footage. The snap on design made it easy to swap filters quickly.Positives• Noticeable improvement in motion blur control when filming in bright light• Polariser helps reduce reflections and deepen skies• Snap on fit feels secure with no wobble during movement• Good image clarity with no obvious colour shiftNegatives• Filters add a little bulk to the camera• Need to be careful keeping them clean as fingerprints show easilyOverall impressionFor anyone filming outdoors with an Action 6, these filters make a real difference to footage quality. They are especially useful in sunny conditions and feel well made for the price.

I have other filters from K&F and have yet to be dissapozted, these are no exception, in fact I recently reviewed a set of 3 for this camera and didn't think I could have been happier.I was wrong.On that review I wrote the following -"They attach easily and - more importantly- come off just as easily.if it is your first time using these then you may find the factory fitted lens protector quite difficult to remove, this is put on by machine and experience tells me some are very tight indeedDon't be afraid of breaking it, just persevere and it will eventually loosen and spin off"- This set goes that one step further as they just push on over whatever lends protector you currently have on without the need to unscrew and remove it.They are child's play to mount, child's play to remove, with the usual optical and build quality I have come to expect from this company.If you are looking for a set of ND's, stop now, you have found them!
