Canon BG-E6 Battery Grip for Canon 5D Mark II Digital SLR - Reta

Canon Branded Retail Package
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 IIs movie mode or Live View, the BG-E6 is an outstanding accessory.
Many users find the battery grip can enhance camera handling, especially for shooting vertical pictures.
