Canon BG-13 Digital camera battery grip Black

The Canon BG-E13 Battery Grip is an optional battery grip with improved ergonomics designed specifically for the Canon EOS 6D. It allows users to load a choice of one, or two LP-E6 battery packs. With two packs, the already-impressive battery life is doubled, compared to using a single LP-E6 pack in-camera. In addition, with the included battery magazine, you can also run the camera off six AA batteries. With a large number of operating controls including shutter button, Main Dial, multi-controller, AF point selection button, AE lock/FE lock button, AF start button, and multi-function button, the BG-E13 is ideal for high volume and easy vertical shooting.
