The Panasonic lumix G9 is compatible with the vertical shooting battery grip DMW-BGG9. By using two batteries, one in the camera and the other in the grip, the DMW-BGG9 extends the battery life for longer shooting time. It also makes handling more comfortable even in vertical angle shooting. It also provides intuitive operation with a joystick. Exclusively designed for the lumix G9, the DMW-BGG9 perfectly matches the cameras rugged, splashproof, dustproof and freezeproof design.
