The K&F CONCEPT ND Filter Kit comes with four screw‑on lenses (ND8, ND16, ND32, ND64). You do need to remove the original lens to use them, which can be a bit annoying, but it’s quick to do—and honestly, the picture quality is better this way since you avoid stacking double lenses and possible fingerprints. The filters seem quality‑built and feel solid in hand. Used properly, they really enhance video quality and help prevent overexposure by controlling the amount of light entering the camera—without affecting colors. Different filters work best at different times of the day, so the set gives you flexibility depending on lighting conditions.Overall, they do exactly what they’re supposed to do. A reliable, well‑made kit that makes a noticeable difference in footage quality. Definitely worth it if you want more control over exposure and smoother results in bright environments.

£40 at time of review CPL+ND8+ND16+ND32I 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 the ND32 (as that’s 5 stops), 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 slight colour cast, but it’s really small, but noticeable if you’re really pixel peepingSwapping the filters over is simple too as your simply remove the built in filter and swap it for any of these (you can’t stack filters), comes with a good case too. All in all great set of filtersHope my review was helpful

I picked up this K&F Concept ND filter set to go with the Action 6 and it’s exactly what I was hoping for. Everything feels solid and well finished, which is reassuring when you’re swapping lenses on a small action camera.Fitting them is straightforward. The screw-on design matches the original lens cover, so they go on smoothly and sit securely once in place. I much prefer this style over clip-on filters, especially for outdoor use, as there’s no worry about them shifting or coming loose mid-shoot. They also work fine with cases and accessories, which is a big plus.In use, the different strengths give plenty of flexibility depending on light conditions. Bright scenes are much easier to manage, highlights stay under control, and footage looks more natural overall. Image quality has stayed sharp, with no odd colour shifts or softness that I can see. The glass also seems to resist water and dust well, which makes them practical for real-world shooting rather than just ideal conditions.The set covers all the essentials and feels built for regular use.

This kit has just about everything you need to prescribe to the 180 rule which requires setting your shutter speed to double your frame rate. This ensures you can maintain more natural motion blur than what is normally experienced with action cameras. In addition to the the ND filters that work as sunglasses for your camera you get a CPL which aids in minimizing reflections off glass and water surfaces. Bear in mind that these are screw in filters so you have to remove the protective lens from the OA6 before you put them on. This will add time to swap, leaves the lens on your OA6 exposed to dirt/dust but from my perspective is a better option in that there is less glass between your subject and the interior lens on the OA6. i would also recommend these over the slip on version for those who really are using their camera in an action setup, these have no chance of just popping off during strenuous activity. Many other filter options for the OA6 slide on which may be quicker but save time and eliminate the risk of dirt/dust lodging on the interior lens. K&F is certainly my first choice in filters for all of my cameras and they offer product at different price points. They provide some of the best value when it comes to filters IMO.

tre range from 8-64 is perfect and the thread-system feels really secure. I like them a lot!

The K&F CONCEPT ND and PL filter kit is designed for use with the DJI Osmo Action 6, providing users with four different neutral density options (ND8, ND16, ND32, and ND64) combined with polarising functionality. This combination allows for greater control over exposure and reduces glare from reflective surfaces, making it particularly useful for outdoor photography and videography.The build quality of the filters is impressive, featuring HD optical glass that feels durable yet lightweight. The 28-layer nano-coating enhances performance, reducing flare and improving clarity. In practical use, these filters allow for smoother motion in video footage and lend a professional touch to still images. The ease of screw-on application simplifies switching between filters depending on lighting conditions.However, there are a few considerations to bear in mind. While the quality is commendable, some users may find the filters slightly heavy on the camera, potentially affecting balance. Additionally, the price point, while reasonable for the quality, may still be a consideration for those on a tighter budget.In summary, this filter kit is a robust choice for filmmakers and photographers seeking to enhance their work with versatile options for light control.Pros:- High-quality HD optical glass- 28-layer nano-coating reduces glare and flare- Variety of ND and polarising options availableCons:- Not the best in low light conditions, but that's not what these are made for- Price may be a consideration for budget-conscious users

Come in a very nice box and fit the camera well. I haven't tried all of the lenses out yet but I am happy with these.

Very good quality and fully compatible with my Osmo Action 6. Essential to be able to have good shots when there is a lot of natural light. Recommended.

I’ve used the Osmo Action for a few months now, mainly for the kids football matches and the odd mountain bike trail. While the camera is top notch, bright days can make the footage look a bit amateur and blown out. I picked up this ND/PL set to try and get a more professional look, and they have barely left my camera since.I think the build quality is great for what you pay. The filters use the same screw mechanism as the original lens cover, so they feel solid and won't fly off. The glass is easy to clean with the supplied soft cloth.Functionally, having the ND and polarizer in one is a massive time saver. You get four filters ranging from ND8 to ND64, which covers everything from a typical grey afternoon to a rare blast of bright sunshine. The lower ones are great for getting that smooth motion blur on the kids running about, while the stronger ones are brilliant for cutting glare off the water during trips to the coast.In terms of value, it is a bit of a no-brainer for any dad wanting better family videos. They are waterproof, fit in my existing case, and cost the same as a couple of pizzas. If you want your holiday clips to look more cinematic by lowering the camera shutter speed without a load of messing around, these are definitely worth a shout.

This is a nice set of neutral density filters that covers all the common light reduction levels: ND8, ND16, ND32, and ND64.These filters are attached by removing the lens protection glass from the camera and screwing a filter on instead. Installation is a bit more tedious than the push-on style filters, but the screw on type is also much better for use in wet weather, and since I live in the soggy Northwest, that's important to me.The quality feels very good with optical glass and metal construction. The glass is flush with the outer metal edge, making it easy to give the glass a quick wipe with the included cloth. All four filters thread onto my camera smoothly. They come in a padded plastic storage case to keep them safe and clean.Overall, this is a nice set of filters and are a lot of fun to experiment with to get different effects like motion blur, or just for help reducing over exposure on very bright days.
