Comments about Chrosziel AC-450-22 Flex-Ring Flexible Step-Down Ring (110:50-85mm):
This step down ring (aka "doughnut") keeps light from reflecting off filters and back into the lens; it works with the AC-450 matte box and with lenses that have 50-85mm diameter fronts. It threads into the matte box's 110mm ring; the rubber ring stretches to fit around the lens front. It is especially good for lenses that expand and contract a bit as you focus or zoom them.
