If you're into action videography with your GoPro—whether it’s Hero 9, 10, 11, 12, or the latest Hero 13—this variable ND filter is a game-changer. It lets you control how much light hits your lens, so you can shoot smooth, cinematic footage even on super bright days. Just twist the ring to adjust between ND4 and ND32 (that’s 2 to 5 stops of light reduction) and get that perfect exposure without overblown highlights. Love motion blur? This filter helps you capture fluid movement in waterfalls, traffic, or sports. The attachment is super secure—it screws on tight and won’t budge during intense activities like surfing, biking, or hiking. Made with multicoated HD optical glass that resists scratches and smudges, it stays clear and easy to clean. The frame is slim and lightweight, crafted from tough CNC aluminum alloy, so it won’t weigh down your setup. Note: While the filter has a waterproof coating, remember it’s not meant for underwater use—keep your GoPro above the surface! Perfect for vloggers, adventurers, and anyone wanting pro-level video straight from their action cam.
