Canon BG-E6 Battery Grip

Manufacturer Description

The BG-E6 is dedicated strictly to the new EOS 5D Mark II, and permits up to two LP-E6 battery packs to be installed.  With two packs, the already-impressive battery life is doubled, compared to using a single LP-E6 pack in-camera. Especially for extended use of the EOS 5D Mark II's movie mode or Live View, the BG-E6 is an outstanding accessory.  Like previous Canon battery grips, the BG-E6 provides full vertical shooting controls, which can be independently turned on or off as the photographer desires.
