The PG-T2I Deluxe Power Grip for the Canon T2i from Vivitar provides easy and comfortable vertical shooting. It accepts two LP-E8 lithium-ion batteries as well as six "AA" batteries. The added power gives you rapid shooting in scenarios you might not normally be able to get results in with only the standard camera battery. The unit features AF point selection, aperture control and magnify functions.
A handy 1/4 x 20 tripod mount is located on the bottom. The firm grip attaches and detaches to the camera in seconds. An additional benefit to the grip is that it gives you added heft to your DSLR by providing more surface area to hold on to.
Note! Batteries sold separately
