The Nikon MB-D10 is a vertical grip and battery holder for the Nikon D300, D300s, and D700. It accommodates an extra EN-EL3e battery, an EN-EL4a, or 6 AA batteries. This MB-D10 is in very good cosmetic condition, with minor wear from normal use and handling; it includes the standard tray, one Nikon EN-EL3e battery, the BL-3 chamber cover, and the MS-D10 AA battery tray. Also included: a Really Right Stuff L-bracket with Arca-type mounting surfaces.
