PolarPro Intermediate ring 82mm filter on 72mm thread QuartzLine

The step-up ring expands the compatibility range for your filters to lenses with a smaller diameter. For example, our 67mm-77mm step-up ring would allow your 77mm QuartzLine filter to fit your preferred 67mm lens. Equipped with a deeply knurled, CNC-machined brass frame for easy mounting and durability, as well as a galvanically matte black finish to prevent unwanted reflections, our step-up ring is designed for use in production, outdoors in the elements, or in the studio.
