I recently tried the K&F Concept 4-Pack CPL ND8 ND16 ND32 Filters designed for my Insta360 GO Ultra, and they are a fantastic upgrade for anyone looking to elevate their footage. This set includes a CPL (Circular Polariser) and three neutral density filters (ND8, ND16, ND32), gives you a number of options to control exposure and reduce unwanted reflections. - like sunglasses for your camera... wear your sunglasses and look at the clouds and see the difference, this is how they change your footage and make them just... chiefs kiss.Over all performance:The CPL filter works wonders for cutting glare on reflective surfaces like water or windows, making colours appear richer and more vibrant.The ND filters allow for more cinematic motion blur by slowing down the shutter speed without overexposing the image, even in bright daylight.The combination of these filters makes footage look smoother, with improved contrast and a professional finish - check your shutter speed if you are in Manuel mode for smoother footage.Build Quality:The filters are lightweight yet feel sturdy, perfectly balanced for the Insta360 GO Ultra.They attach securely and do not disrupt stabilisation or introduce vignetting. Easy to fit.Overall Impression:These filters are a must-have for creators who want to achieve more polished and dynamic shots. Whether filming landscapes, action footage, or urban scenes, they give a noticeable boost in image quality and creative flexibility.
