Made from a tough magnesium alloy the BG-D800M for the Nikon D800 is the pro’s choice – the ultimate battery grip. This battery grip can hold one EN-EL15 or eight AA size batteries to offer double-length shooting time. It is also equipped with a vertical-grip shutter button, dual control dials, multi-function controller and an AF-ON button to make shooting with the camera in a vertical position just as comfortable as shooting horizontally.
