(Panasonic DMWBGS1)

OVERVIEW

By using two batteries - one in the camera and the other in the grip* - the Panasonic DMW-BGS1 doubles the battery life for extended shooting. Charging the camera via USB simultaneously charges the battery in the grip. Exclusively designed for the LUMIX DC-S1R/ DC-S1, this accessory also makes gripping more comfortable, even in vertical angle shooting. It perfectly matches the camera, featuring the same style of buttons and intuitive joystick control. This grip boasts rugged dust- and splash-resistance and is designed for use at temperatures as low as -10 oC.**

PLEASE NOTE: No battery pack is bundled with the DMW-BGS1.

Dust and Splash Resistant does not guarantee that damage will not occur if this battery grip is subjected to direct contact with dust and water.
