Canon BG-E7 Battery Grip for Canon EOS 7D DSLR Cameras
The Canon BG-E7 battery grip is the official Canon battery grip for the Canon EOS 7D digital SLR and offers the user multiple power options plus vertical control. The BG-E7 will hold up to 2 Canon LP-E6 batteries to offer a greater shooting duration. As an alternative the BG-E7 grip can be used with 6 AA batteries. This not only increases shooting times but also means that the universally available AA batteries can be used in the event that your lithium ion batteries fail. The Canon BG-E7 grip also makes holding your 7D in the vertical or portrait position more comfortable. Shutter release, main dial, AF Point Selection, AF/FE Lock, Index, Aperture, Exposure Compensation Button and Reduce Button functions are all replicated on the grip, making operation of the camera more convenient when shooting in the portrait format.
