The Nikon MB-D14 Multi Battery Power Pack gives you a firm, steady grip on the D600 that you'll appreciate with longer lenses or low shutter speeds. The grip also gives you greater control when in the vertical or portrait position. Instead of grappling for control on the camera body, the grip provides an easily accessed vertical shutter release button, AAE/AF lock and dual command dials.
Optional Nikon MS-D14 AA Holder allows you to use Ni-MH, Alkaline or Lithium AAs, as well as a MS-D14EN Battery Holder for use with EN-EL15 battery. 6 AA Alkaline batteries will give you about 450 shots while the optional EN-EL15 battery will give you an impressive 1,800 shots.
The AA battery Cartridge will not be included in the rental unless specified in the special instructions section.
The rental is for the grip only and does not include a battery.
