The walimex pro battery handle extends the battery life of your camera and omits cumbersome battery changes. The battery compartment offers the option to use an additional EN-EL 15E battery or 6 AA batteries in addition to the camera powerpack. For easy operation of the camera during portrait orientation photographs, the handle is equipped with an ergonomically shaped, rubber coated portrait orientation trigger. Aperture and shutter settings can be adjusted with two dials. In addition, the battery handle is equipped with a button and a joystick for activating and selecting the AF measuring fields and with an infrared remote control for wireless triggering. Of course the battery handle also features a ¼ inch tripod connection for mounting on a tripod during longer shootings.
