PolarPro Step Up Ring 72-77mm Filter Adapter This practical adapter increases filter compatibility so you can use it with smaller lenses. This gives you even more options for recording original footage. For example, the Step Up Ring 72-77mm by PolarPro will allow you to mount a 77mm filter on a 72mm lens. The knurled brass frame makes the accessory easier to mount and more durable. What's more, the matte black electroplated surface eliminates unwanted reflections. All this makes the Step Up Ring perfect for recording both in the studio and outdoors.
