|The Canon battery grip BG-E6 can be operated with one or two LP-E6 battery packs installed. With two packs the power capacity available to your EOS camera is doubled compared to using a single LP-E6 pack in-camera. Alternatively the grip and camera can be powered using six AA batteries via the supplied holder BGM-E6. For extended use of Movie Mode or Live View the BG-E6 is the ideal accessory. The BG-E6 also provides full vertical shooting controls, which can be independently turned on or off as you desire. Many users find the battery grip can enhance camera handling, especially when shooting vertical pictures.
Fits the following EOS models:
EOS 5D Mark II
