| The Vivitar Battery Grip for the Nikon D3100 & D5100 uses EN-EL-14 battery packs, thereby doubling the shooting time of the camera. Features a vertical shutter release that makes shooting with the camera in a vertical position just as comfortable as shooting horizontally. Supports features such as AE and FE lock, with access to the Index/Reduce button, main dial, AF-Frame Select button, and Aperture/Exposure Compensation Button. Improves stability, and includes an integrated tripod mount. |
