The Targus TG-BGD200 Vertical Battery Grip for the Nikon D200 digital camera functions as both a high-capacity battery pack and a vertical grip. It holds 2 EN-EL3e battery packs, thereby doubling the shooting time of the camera, and allows for the use of six AA batteries in the supplied battery magazine.
It also features a vertical shutter release that makes shooting with the camera in a vertical position just as comfortable as shooting horizontally.
Additionally, it supports features such as AE lock and AF lock with access to the Index/Reduce button, main dial, AF-Frame Select button, and Aperture/Exposure Compensation Button.
