NEEWER CPL + ND Filter Set FL-B100 for DJI Osmo Action 6 (4 Pack: ND8/16/32 + CPL)

The essentials

If you shoot with a DJI Osmo Action 6 and want more control over light and reflections, this NEEWER CPL + ND Filter Set (FL-B100) is built for that exact job. It’s a 4-pack including ND8, ND16 and ND32 neutral density filters plus an adjustable circular polarising (CPL) filter, so you can dial in exposure and tame glare when conditions get bright or reflective.

On paper, it’s the kind of “creator essential” accessory that makes a noticeable difference when you film fast-moving POV action, not just static scenes. Where it shines is simple: reducing light when you need calmer, balanced exposure, and using polarisation to cut reflections off glass, water and other non-metallic surfaces.

Key points

The set is designed specifically for the Osmo Action 6, using a screw-on approach once you remove the original lens. That makes it straightforward to swap filters between outings—handy when your lighting changes from indoor to bright outdoor, or from clear skies to more reflective surfaces.

The CPL filter is adjustable, which matters because glare doesn’t always come from the same angle. Turn it to reduce reflections and help saturation and contrast look more convincing, especially on water or glossy surfaces.

Just remember: this is an “in-use control” set, not a magic fix for difficult lighting. If you’re already coping with very low light, ND filters will still reduce light further—so it’s not a match for every situation.

What matters in real filming

ND8, ND16 and ND32 are there to reduce light and help you keep exposure under control across different environments. In practice, that’s useful when you’re capturing movement in daylight and want to avoid overexposed highlights. The larger the ND value, the more aggressive the light reduction, so you’ll tend to use higher values (like ND32) when the sun is strong.

You can also use ND filters creatively to achieve motion blur effects. That can turn a bright bike ride, run, or skate session into footage with a more cinematic look—assuming your shooting approach suits that style.

And when the scene is reflective, the adjustable CPL filter becomes the practical lever. Think of filming over a lake in summer, or capturing action near windows and shiny surfaces—this set is aimed at minimising reflection and glare while improving the punch of colours and contrast.

Key features and build

This filter set uses HD optical glass with multicoated surfaces on both sides. The coatings are intended to help with image clarity, while also offering protection against water, scratches and fingerprints.

The attachment is screw-on, and the set is meant to lock into place once fitted. That’s a sensible choice for intense sports like skiing, skydiving, skateboarding, running and cycling, where you don’t want accessories wobbling around.

Still, there’s one limitation worth noting: it’s only compatible with DJI Osmo Action 6. If you own a different action camera model or plan to use the filters on another body, you’ll need to look elsewhere.

Usage tips

A typical workflow is to start with ND8 on bright days, then step up to ND16 or ND32 if highlights start to blow out. If you’re near water or glass, consider using the CPL filter and adjust it until the glare reduces—often you’ll notice the change immediately.

If you’re filming outdoors sports, it can help to pre-plan based on where you’ll shoot most. On a sunny training session, you’ll likely rely on the ND filters more, whereas for a reflective location (coastlines, rivers, urban glass), the CPL filter can become your go-to.

Also, because the filters are screw-on, handle them carefully during quick changes—especially if you’re swapping them between runs. It’s the sort of accessory where small handling habits matter.

Tech specs

• Compatibility: DJI Osmo Action 6 only
• Included filters: ND8, ND16, ND32, adjustable circular polarising (CPL)
• Filter pack: 4 filters total
• Attachment method: Screw-on (remove the original camera lens and lock the filter in place)
• Glass: HD optical glass with multiple protective coatings on both sides

Who it suits (and who should skip it)

It makes sense if you regularly shoot bright outdoor action with the Osmo Action 6 and you want practical control over exposure and reflections. Content creators and influencers working with POV footage will likely appreciate having ND options and a CPL filter in one pack.

It might not be the best match if you mostly film in low light, because ND filters reduce light further. It’s also not for you if you’re using a different camera than the Osmo Action 6, since compatibility is limited.

Worth considering if your filming locations include water, glassy surfaces, or places with strong reflections—those are exactly the moments where polarisation helps most.

Is it worth it?

Buy this NEEWER CPL + ND Filter Set if you’re shooting with DJI Osmo Action 6 and want a set that helps manage bright conditions, reduce glare, and keep footage looking more balanced and punchy. The screw-on design and protective coated HD optical glass are a sensible pairing for active use.

Avoid it if your plans are mainly low-light, or if you’re not using the Osmo Action 6 specifically. In those cases, the value drops because ND filters won’t help and the compatibility won’t cover your camera setup.
