There is a 1/4in screw hole at the bottom, which can be fixed to the tripod. 2. Long Endurance: The vertical battery grip can accommodate 1 or 2 NP FZ100 batteries, doubling the battery capacity and increasing the endurance of the camera, thus extending the shooting time and supporting high strength shooting. 3.
