Vivitar Battery Grip for Canon Eos Rebel Xsi

The Vivitar Deluxe Power Grip [VIV-PG-XSI] provides the power you need for the Canon EOS Rebel XSi and TS1 SLR digital cameras. It adds to the power by using 2 LP-E5 rechargeable, high-capacity batteries, or use 6 AA batteries. In addition, the battery pack provides a vertical shutter release, that makes holding the camera in the vertical orientation as easy and secure as in the horizontal position.
