Fotodiox WonderPana Go 77mm Step Up Ring
Pro WonderPana Go 77mm Step-Up Ring – GoTough Filter Adapter Step Up Ring für 77mm Standard Filter
Don’t let anyone tell you it’s impossible to mount filters on a GoPro camera. We took our professional WonderPana filter system, and miniaturized it to fit everyone’s favorite sports camera; the GoPro HERO3. And with these step-up rings from Fotodiox, you can now fit a wide variety of existing standard filters onto your GoPro camera using the GoTough WonderPana Go*.
*Must already have the GoTough WonderPana Go filter system for HERO3+/4 for the Step-Up Ring to work.
