What you're looking at is the Tilta 15mm to 12mm Dji Rod Adapter, a versatile and robust accessory designed to bridge the gap between your Dji Rs Focus Motor and a traditional 15mm Rod Mount. This black, 8-inch rod adapter is engineered with a 15mm diameter on one end and a 12mm diameter on the other, making it an ideal fit for 15mm rod holders commonly found on lightweight baseplates or our Single Side Rod Holders. The unique design of this Dji rod adapter ensures a secure connection, significantly reducing the risk of the focus motor detaching from the lens. This feature is particularly beneficial when working with a rigid lens or a lens adapter. Inside the 15mm end of the rod adapter, you'll find 11mm threads. This thoughtful addition allows for the extension of the rod's length, providing you with the flexibility to adapt to various shooting scenarios.
