Cavision 117 to 127mm Threaded Step-Up Ring

This step-up ring allows the use of 127mm threaded filters on lenses with 117mm filter threads. The 9mm depth helps fill the gap between the lens and the back of select rod-mounted matte boxes, reducing reflections. The ring has a 130mm outside diameter for compatibility with clip-on matte boxes. It is made from lightweight aluminum alloy with a black anodized finish.
