Vivitar PG-T2I Deluxe Power Grip for Canon T2i

The Vivitar Deluxe Power Grip holds 2 LP-E8 batteries, providing twice the power. It also includes an adapter that allows you to place 6 AA batteries for extended shooting time. The Power Grip provides a Vertical shutter release button, and easy power on/off switch.

This option makes shooting with the camera in a vertical position just as comfortable as shooting horizontally. The Power Grip attaches through the tripod mount on the bottom of the camera to further improve stability. A Vivitar three year limited warranty is included.
