Extend the battery life of select Lumix Micro Four Thirds cameras while also improving ergonomics during vertical shooting with this DMW-BGG1 Battery Grip from Panasonic. It holds one DMW-BLC12 battery pack, in addition to the battery in the camera, for twice the power and provides a second shutter release button, an AF/AE lock button, an exposure compensation button, and dual control dials. This setup mirrors the design of the camera body for intuitive switching from horizontal to vertical orientation. One DMW-BLC12 battery pack is included with the grip.
