This is an excellent quality set of ND filters from K&F Concept designed specifically for the Osmo Nano. The set includes four filters with different levels of darkness, and what I appreciate most is that you can fine tune the density directly on the lens once it is installed. This is a noticeable upgrade from other ND filters I have used that only offer a fixed setting. Having adjustable control gives you a lot more flexibility when you are shooting in bright environments or when you want to achieve smoother motion blur for video.Installation takes a little extra effort. You do have to remove the original lens cover and lift off the protective case before these filters can be screwed in. Because of that, it is not the fastest option if you plan to switch between different lighting scenarios quickly. However, once attached, the filters feel secure and well made, and they deliver a clean and consistent image.In actual use, the filters create a strong anti glare effect and help maintain proper exposure without blowing out highlights. They work especially well for outdoor footage where lighting can shift throughout the day. If you film a lot with the Osmo Nano and want more creative control over your shutter speed and exposure, this set is a great addition to your kit. It offers strong clarity, smooth adjustment, and reliable build quality at a very good value.

Love K&F Concept and all of their camera products. This is another quality product. More than enough ND stood for all situations. Not sure when I’ll use ND256 unless I’m shooting something on the sun but it is nice to have. The filters thread on nicely and sounds like they are made of metal. They also all have gaskets to ensure water doesn’t enter the lens. Really happy with the product. Included plastic case makes it easy to keep the filters organized and protected. I wish top of the plastic storage case also had a thin protective layer. I just lay one of the included microfiber cloth flat on top of the filters before closing the case but it is pretty inconvenient to do it every time or when you are on the go.

Typical K&F quality filters and packaging.So I've used the ND16 PL and the ND32 PL during a overcast day and a partly sunny day at the beach nearby.The filters provide a nice depth of field and have the benefit of cutting down on glare due to the multi layer coating each of these filters have.Easy to install and remove.One thing to note. The Polarizer feature of these filters is on the "light" side for the effect.They are not as strong as a stand alone Polarizer so be aware, they do provide a small amount of polarization to cut down glare off the water, but if you need a strong PL filter effect, you are best served by using a stand alone PL filter.These fit nice and snug on the Osmo Nano's lens and they rotate smoothly to adjust the PL filter to match your lens/camera orientation.Super easy to use and I have to stress again, the coatings are lab quality with no uneven or wavy sections.So if you need effective light control but do not need strong polarization control, I'd recommend you pick up a set of these filters as they are a great price for an excellent quality filter set.

These filters give you better exposure control on the Osmo Nano. The hybrid ND and PL design helps manage bright light and cuts reflections, which makes outdoor shots look cleaner.The glass stays sharp, and the coating protects against scratches and smudges. A solid add-on if you want more control over your footage.

The K&F Concept ND/CPL Filter Set for the DJI Osmo Nano is a fantastic upgrade for anyone serious about elevating their video quality. The 4-pack set (ND8, ND16, ND32, CPL) gives you all the essentials for handling bright outdoor conditions, motion shots, and reflective surfaces. The filters lock in securely, fit perfectly, and feel well-built—not flimsy like cheaper alternatives. The multicoated HD optical glass noticeably improves clarity and reduces glare without distorting color. Whether you're shooting travel vlogs, action clips, or cinematic scenes, these filters deliver consistent, professional-looking results. Compact, lightweight, and easy to switch out on the go—this set is a must-have for Osmo Nano creators.

Great compatible filters.

The optical quality is excellent for the price—sharp, with good contrast, and minimal loss of detail even at the strongest ND filters. The inclusion of six filters (ND8, ND16, ND32, ND64, ND256, and CPL) ensures that I’m covered from everyday daylight to brutal noon sun or snow without ever needing to switch to a different brand or strength.I was able to take a smooth timelapse in a birght day(SS 1/2", ISO 100, 2 sec interval).While the filters are great, a small carrying case or pouch would have been a welcome addition. Currently, they only come in a bulky plastic case. There is some color shift, but it’s acceptable considering the consumer price point.

Must have for anyone who wants to take their footage from ordinary to awesome. The assortment gives you every filter you need for any type of light. Sun, city, water, you’re covered.

PROS-good fit (they stay firmly attached because they are screwed in and not pressed on, which is good as I tend to use my Nano hand-held or on a stick and it does get bumped around a lot)-good knurls, makes it a lot easier to screw them on/off-they are robust (I didn’t try to scratch them, but I’m glad they are resistant, as that is my main problem with attachable filters)-I see no reduction in sharpness (though i tend to edit down to 1080 anyways)-decent value for this set at £39.99CONS-slight image colour shift as you move up the various strengths (not an issue if you set white balance properly)-photo number 3 in this listing shows a fundamental lack of understanding of what ND filters are for (they are for slowing down shutter speed, or allowing for use of wider apertures in bright conditions, neither of which are demonstrated by the images in photo 3)NOTES-it’s always nice that I can set my exposure to a more “cinematic” look, even though few seem to consider that a desirable look when working with action camsMY STAR RATINGS:1* substandard, mostly cons2** barely acceptable, cons outweigh the pros3*** meets the basic requirements, cons balance the pros4**** good product, pros outweigh the cons5***** exceptional, all (or almost all) pros

The quality of these filters is spectacular, this brand never disappoints.
