The 37mm Phone Filter Mount attaches any standard 37mm filter over a single lens on your camera phone using the Moment Drop-in Mount on your Moment Case. We offer an M-Series version and a T-Series version of this mount, both securely attaching a 37mm filter to your phone. A 37mm is a sniper’s approach to mounting a filter over just one of your camera phone’s lenses. Made of aerospace-grade stainless steel, this mount is designed with the same rugged construction used on our indestructible camera filters. If you want to attach a filter over all three lenses on your phone, you need the Moment 67mm Phone Filter Mount. If you want to attach filters to your Moment Lenses, you’ll need our 67mm Lens Filter Mount.
