Canon BG-E8 Battery Grip for Canon EOS 550D
The Canon BG-E8 is the battery/vertical control grip for the Canon EOS 550D digital SLR Camera. It allows two BP-E8 batteries to be used simultaneously to allow for longer shooting times. The Canon BG-E8 also provides a more comfortable grip when using the EOS 550D in the vertical/portrait orientation as key controls such as the shutter release button are duplicated on the grip to provide easier use when the camera is rotated through 90 degrees.
