Takes two EN-EL15 batteries
Doubles the camera’s battery life
Vertical shutter button
Phottix BG-D7100 Battery Grip for Nikon D7100 digital cameras doubles the length of shooting time and eliminate the need for frequent battery changes by using two EN-EL15 batteries or six AA size batteries before running out of charge. An additional shutter-button allows the shutter to be triggered more comfortably when the camera is used in portrait orientation.
This grip is compatible with Phottix or Nikon EN-EL15 batteries.
