The two-part top plate includes ¼-20 and 3/8-16 threaded holes for accessory attachment. It is designed to provide easy access to the camera's sensors' reference pin. It's lightweight (70 g) and made of CNC aluminum. Another feature of the top plate is that it can be installed on one side only if required, as it comes in two separate parts, and as such, it is perfect for drone and gimbal applications. The top plate system was designed with a lightweight system for mounting any standard 15 mm accessories. A top plate viewfinder solution with rods and a Sony screen mount adaptor can be installed on the top plate (FS5TPKIT).
