I’ve been a working commercial photographer for 40+ years, and ND filters are just part of my normal workflow on DSLR and cinema glass. Using them on an action camera is the same idea: slow the shutter, control exposure, and keep footage from looking harsh or overly “video-ish” in bright light. This K&F Concept kit for the DJI Osmo Action 6 does that well.My experience after real-world shooting:Accuracy of listing: Spot on. What they promised is what showed up, and it behaves as described.What’s in the kit: ND8, ND16, ND32, ND64 — a useful spread for anything from mildly bright to very harsh daylight.Image quality: Clear optical glass with solid coatings. No strange color cast in my footage, and no noticeable softening. Footage still looks clean and sharp.Functionality / exposure control: Works exactly as ND should — lets you keep shutter speeds reasonable so motion looks more natural instead of overly crisp.Fit & installation: Secure, lightweight, and didn’t mess with the camera balance. Attaches cleanly and stayed put.Lens protection: Bonus benefit — you’re keeping fingerprints, dust, and small debris off the actual camera lens.Build quality: Feels like quality gear, not toy accessories. Coatings seem durable, and the frames are thin enough to avoid vignetting.Value for money: For four filters, the price feels fair. Cheaper than “premium brand” sets but doesn’t feel cheap.Small note: This isn’t a “dramatic transformation” accessory — it’s a tool for better control and more professional-looking footage. If you shoot a lot outdoors, it’s genuinely useful.Bottom line:If you’re running a DJI Osmo Action 6 and want reliable ND filters to tame bright light and improve motion quality, this is a good, honest kit that delivers. I’ll keep using it.
