The Panasonic DMW-BGG1 Battery Grip is designed to extend the battery life of your LUMIX G85 or LUMIX G95 Mirrorless Camera, while improving your control & comfort during a shoot. The DMW-BGG1 Battery Grip holds one DMW-BLC12 battery pack (included), in addition to the battery that is normally in your camera, allowing you to have twice the power. A second shutter release is also included, as well as an AF/AE lock button, dual control dials, and an exposure compensation button. The design of the battery grip is meant to create a user-friendly setup for intuitive switching from horizontal to vertical shooting.
