2" (M48) to 31mm Unmounted Filter Adapter for Starizona Filter Slider (Filter Drawer)
This filter step ring is made specifically with the Starizona Filter Slider system in mind. It steps the M48 threads of a standard 2" filter down to a 31mm unmounted filter holder. There are nylon retaining screws to hold the filter in place. The step ring has a 2" outside diameter, so it can also be used in many other applications in addition to the Filter Slider.
Images are for demonstration only. Only one step down ring is included.
