The Battery Grip for Lumix GH3 and GH4 Digital Cameras from Panasonic is designed for the Panasonic GH3 and GH4 digital mirrorless camera and accepts one Lithium-Ion battery in addition to the battery in the camera body. With two batteries installed, your shooting time is effectively doubled.
The design of a battery grip offers a comfortable and secure way in which to hold your camera, especially in the vertical position. This battery grip features an alternate shutter release button and additional control buttons and command dials to facilitate shooting when the camera is held in the portrait orientation. In addition, it is designed with anti-slip rubber grip to further improve handling, a tripod socket to mount your camera directly to a tripod and a holder for the camera's contact cover so as not to lose it when the battery grip is installed. The grip is weather-sealed to match the durability of the GH3 and GH4.
