Battery Grip BG-E11 for Canon 5D Mark III
For buying product; Battery Grip BG-E18 (For 750D, 760D)
The 5D MARK III Battery Grip is an optional battery grip with improved ergonomics designed specifically for the Canon EOS 5D Mark III. 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. This is especially useful when taking advantage of the camera’s movie mode or Live View mode – operating modes that use more power. In addition, with the included battery magazine, you can also run the camera off six AA batteries.
The BG-E11 also provides full vertical shooting controls, which can be independently turned on or off as the photographer needs to enhance camera handling, especially for shooting vertical pictures. It has a large number of operating controls as well: shutter button, Main Dial, multi-controller, AF point selection button, AE lock/FE lock button, AF start button, and multi-function button.
