The ingenious design of the grip lets you hold the camera firmly. The Vertical Grip allows you to shoot photos easily and enjoyably regardless of whether you hold the camera horizontally or vertically, making it easier to concentrate on the subject and composition. Batteries in the vertical grip can be recharged via the camera’s USB port, without detaching the grip from the camera. For extended shooting sessions, extra power can be supplied direct to the camera via the camera’s USB port¹ using a mobile battery or AC adaptor to supplement battery power
