The MB-D16 Battery Grip from Jupio is designed for the Nikon D750 DSLR Camera. It holds a single EN-EL15 battery, and this ergonomic device provides added comfort, stability, and control while shooting in both the portrait and landscape positions. A heavy-duty wheel lets you lock the unit tightly to the camera, and for added convenience and functionality, the grip features a shutter release button, main command dial, sub command dial, joystick, and AE lock button. If you don't have a charged camera battery on hand, you can use 6 x AA batteries inside the grip in an emergency.
