Product description
At a glance
If you’re shooting with the DJI Osmo Nano and you want more creative control over reflections and motion blur, this K&F CONCEPT CPL plus ND set is built to do exactly that. It’s a multi-filter kit rather than a single “one size fits all” accessory, so you can adapt to bright days, glarey scenes and everyday outdoor filming.
On paper, the pitch is simple: CPL helps cut reflections and enhance colour saturation, while the ND filters (ND8, ND16 and ND32) tone down incoming light so you can achieve smoother blur effects. The other side of the story is protection and practicality: it’s designed for a specific Osmo Nano setup, uses multi-coated optical glass, and is meant to handle wet conditions.
Before you buy, though, it’s worth being realistic about the trade-offs. An ND kit doesn’t automatically make footage look cinematic in every situation—it mainly gives you the option to slow things down with the right shutter/creative settings. If you mostly film indoors or in consistently dim light, you may not use all three NDs.
Key features
What stands out most here is the combination of creative filters and lens-cover style convenience.
- CPL (polarising filter): positioned for reducing reflections and improving colour saturation. This is particularly useful when you’re filming outdoors around water, windows, glossy surfaces or anything that tends to glare.
- ND8, ND16, ND32 (neutral density filters): these are intended to control light levels for smoother motion blur. In practice, that means you can keep exposure in check on brighter days and still create a more fluid look for moving subjects.
- 28-layer nano coating on HD optical glass: described as reducing reflections, repelling water and dust, and providing scratch resistance for clearer results over time.
- Waterproof design with sealed thread: aimed at wet-adventure shooting, such as rain/snow or activities like surfing and kayaking.
- Easy screw-on installation: designed to install in seconds and swap quickly, using a screw-on action said to match the original lens cover style.
What you’ll notice day to day
The “feel” of this set is largely about speed and consistency. A screw-on mechanism that’s meant to be identical to the original lens cover approach matters because filter swaps are something you end up doing repeatedly when light conditions change.
In a typical scenario, say you’re filming a coastal walk: you might start with the CPL when the sea and rocks are throwing back glare. Later, when you want a smoother look to waves and moving water, you’d switch to one of the ND options. When the weather turns, the waterproof/sealed-thread approach is there to help you keep shooting rather than babying the setup.
It’s not perfect in every sense: if you expect hassle-free use without thinking about exposure at all, ND filters still require you to choose the right ND level for the light you’re working with. Also, the kit’s wet-shooting positioning is helpful, but you’ll still want to handle the filters carefully in real conditions.

Who it’s for (and who should skip it)
This makes the most sense if you regularly film outdoors or in changing light, and you’re the kind of person who actively wants to adjust look and feel rather than sticking to a default image.
It’s especially worth considering if you: - shoot scenes where reflections are a nuisance (water, windows, glossy surfaces) - want smoother motion blur options without constantly changing your workflow - care about practical lens protection and coatings that help with water/dust and reduced reflections
It may not be the best choice if: - you mainly film indoors or in low-light where ND filters are unlikely to be useful - you rarely swap filters or never intentionally chase a different motion look - you want something that’s purely “set and forget” with no need to choose between CPL and different ND strengths
Also, it’s built around the DJI Osmo Nano fit. If your setup is different (or you’re unsure whether your case/accessory setup matches what this is aimed at), it’s worth double-checking compatibility details before committing.
Is it worth it?
Worth buying if you’re using the DJI Osmo Nano often, you shoot daylight outdoor content, and you’ll actually use both the CPL for glare control and the ND8/ND16/ND32 range for smoother motion effects. The screw-on swap design and the coated, waterproof-leaning construction are the kind of “every shoot day” details that can make a real difference.
Better avoided if you mostly film indoors, you rarely deal with bright glare, or you’d rather not think about which ND level fits the current conditions. In those cases, a smaller, simpler accessory approach usually saves you money and avoids unused filters.
Quick FAQ
What does the CPL filter do on this kit?
The CPL is intended to eliminate reflections and enhance colour saturation, which can be useful when filming bright outdoor scenes with glare.
What are ND8, ND16 and ND32 used for?
They’re neutral density filters designed to control light levels so you can aim for smoother motion blur effects.
Is it easy to swap filters while shooting?
The set is described as featuring easy screw-on installation intended for quick swaps, using a mechanism comparable to the original lens cover style.
Can it handle wet conditions?
It’s described as waterproof with a sealed thread design, positioned for rain/snow and water activities such as surfing and kayaking.
Will the filters fit with cases and accessories?
The description says it works with most cases and accessories without the need for removal, but it’s still a good idea to double-check your specific setup if you use a particular case or accessory.
