The Flashpoint Professional Camera Grip for the Nikon D750 is a multi-power vertical battery grip that is an optional but essential accessory with excellent ergonomics designed specifically for the Nikon D750. The grip features intelligent links to camera functions, matching the design and feel of your camera. In addition, with the included battery magazine, you can also run the camera off six AA alkaline, Ni-MH or lithium batteries. The non-slip rubberized grip offers perfect balance in any direction with full vertical shooting controls, which can be independently turned on or off as the photographer needs to enhance camera handling, especially for shooting vertical pictures - not videos, please. The grip has generous operating controls as well: shutter button, Main Dial, multi-controller, AE lock/FE lock button, AF start button, and multi-function button. The base of the grip has a standard 1/4-20 tripod socket. Your camera's original battery door fits snugly in a protective hidden slot for instant retrieval. Get a grip.
