The Sensei 37-46mm Step-Up Ring allows you to use regular 46mm threaded filters on lenses with 37mm filter threads, such as the Olympus 14-42mm zoom lens and the 45mm prime lens.

If you have either of these lenses, this Step-Up Ring lets you use any filter that already fits the standard DJI lens - no need to buy another set of filters.

The Step-Up Ring features a lightweight (4gm), aluminum-alloy construction that has a corrosion-resistant, black anodized finish for durability.

It's the easiest and cheapest way to use any X5 filter on any lens with the smaller 37mm filter thread.
