The EG-E7 Battery Grip is Dedicated strictly to the EOS 7D, and permits one or two LP-E6 battery packs to be installed. With two packs, the battery life is doubled, compared to using a single LP-E6 pack in-camera. Especially for extended use of the EOS 7D?s movie mode or Live View, the BG-E7 is an outstanding accessory. The BG-E7 provides full vertical shooting controls, which can be independently turned on or off as the photographer desires.
