Get exactly the look you’re going for with these neutral density filters. Reduce ‘jello’ effects as well as gain a pleasing motion blur in bright conditions. Use them with the built in filter socket inside your Ribcage modified Hero4 camera. Perfect for drone users that want to use a filter with their small M12 lenses. 0.3, 0.6 and 0.9 optical densities included (ND2, ND4, ND8 filter factor). Note: For Hero4 and Yi 4K/4K+ Ribcage Mods only.
