Nikon MB-D12 Multi Battery Power Pack for D800 & D810
Dedicated to the Nikon D810, D810a, D800, and D800E DSLRs, the MB-D12 Multi Power Battery Pack offers both enhanced handling capabilities as well as extended battery life while shooting. It accepts one additional EN-EL15 lithium-ion battery pack to increase the camera's battery life or, alternatively, eight AA batteries can be used in conjunction with the included MS-D12 AA Battery Holder. The design of the grip improves shooting in the vertical orientation and also provides an overall more ergonomic structure for holding the camera. An additional shutter release button, AE/AF lock button, multi selector, and main- and sub-command dials are all incorporated into the grip's design to benefit more natural and intuitive handling.
