It can be used both for vertical shots and to extend the shooting time compared to using the camera battery alone. It can also compensate for the weight of telephoto lenses. The controls for vertical shooting include the shutter release button, main dial and front dial, AF-ON button, sub-selector and function buttons (Fn). With two EN- EL15c batteries in the handle, you get up to 1.9 times longer operating time and can replace the batteries during operation if necessary. You can also charge two batteries in succession via a USB-C port on the handle when the handle is not attached to the camera: perfect for overnight charging.
