The Nikon MB-D15 Battery Grip improves function and battery life of your D7100. It offers a second grip for vertical (portrait) orientation and is equipped with a shutter-release button, AAE/AF lock, directional keypad selector, and front and back command dials. This allows you to control all right hand functions on the camera without moving your hand from the groip.
The battery grip allows you to use a second EN-EL15 rechargeable battery, or can accept six AA batteries (Alkaline, Ni-MH or Lithium). Two battery holders are included, the MS-D14 for use with AA batteries and the MS-D14EN for use with EN-EL15 batteries.
