Extended battery life
By using two batteries - one in the camera and the other in the grip*, the DMW-BGS1 doubles the battery life for extended shooting.
*A battery pack is not included in the DMW-BGS1.
Rugged design
Robust construction and a sealing for every joint, dial, and button make the DMW-BGS1 not only dust resistant and splash resistant* but also operates down to -10 degrees Centigrade.
