The Step-Up Ring expands the compatibility range for your filters to fit smaller diameter camera lenses. For example, our 67mm-77mm Step-Up Ring would allow your 77mm Quartz Line filter to fit your favorite 67mm lens. Featuring a deep knurled, CNC machined brass frame for easy mounting and durability, plus an electroplated matte black finish to block unwanted reflections, our Step-Up Ring is designed for production-grade use, out in the elements or in the studio. Each Step-Up Ring includes a protective hard case.

Backed by our PolarPro lifetime warranty. Aggressively knurled edges provide plenty of grip, while also giving peace of mind in case of the occasional jamming or binding of filters. Matte black electroplated surface helps eliminate reflections. CNC machined brass frame.
