Polar Pro Quartzline 67mm to 77mm Step-Up Ring
Excellent product.!
A little expensive but well worth the money. The build quality is exceptional, just as expected from PolarPro.
The Step-Up Ring expands the compatibility range for your filters to fit smaller diameter camera lenses. For example, the 67mm-77mm Step-Up Ring would allow your 77mm QuartzLine 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.
