More power, better balance & vertical shooting.
The Vivitar MB-D12 Series Multi-Power Battery Grip allows the D800, D800E & D810 to be powered by two EN-EL15 batteries -- one in the camera body and one in the MB-D12 -- effectively doubling your shooting capacity. The MB-D12 also provides a comfortable vertical grip with an additional shutter release and scroll wheel for easy access to the camera functions when shooting in the vertical orientation.
With the included AA battery holder, users can also power the camera with 8 AA batteries.
