The Insta360 GO 3S ND Filter Set provides a versatile range of neutral density filters designed specifically for the compact GO 3S camera. This kit includes four different strengths—ND8, ND16, ND32, and ND64—which allow you to control the amount of light reaching the sensor to achieve cinematic motion blur or capture long exposure shots in bright conditions. Each filter is crafted from a combination of glass and aluminum alloy, with a silicone element to ensure a secure fit. Measuring 20.7 mm in diameter and 4.1 mm in thickness, these accessories are incredibly lightweight at just 1.5 g per piece, meaning they won't add bulk or weight to your small camera setup during active shoots.
