The Nikon MB-D16 is a multi-power battery pack designed specifically for the Nikon D750 DSLR, offering extended battery life and improved handling. This professional-grade grip accepts either one EN-EL15 lithium-ion rechargeable battery or six AA batteries (via the included MS-D14 AA Battery Holder) to significantly extend your shooting time. The ergonomic design provides a more comfortable and stable grip, particularly when shooting in portrait orientation, with integrated controls including a shutter-release button, AE/AF lock button, multi-selector, and main- and sub-command dials for intuitive vertical shooting. Constructed from durable magnesium alloy, the MB-D16 combines enhanced functionality with professional-grade build quality for demanding photographers.
