With a silicone inner lining, the Ulanzi ND32 Filter safely attaches directly to the HERO9 lens tool-free. It allows you to reduce the amount of light hitting the camera sensor in bright outdoor environments, so the sun doesn’t wash out your shot and you can capture more accurate images. With an ND filter attached, you can have proper control over exposure and shutter speed, which otherwise would have to be adjusted to extremes to match the sun’s brightness. The filter is designed with optical glass with multiple layers of waterproof and oil-resistant anti-reflection coating.
