This black Vertical Battery Grip from Sony allows for long-term, comfortable shooting in the vertical orientation with your Alpha a7/a7R/a7S digital camera. It accepts 1-2 NP-FW50 batteries, which are available separately, to extend and possibly even double your shooting time. The grip uses a battery with lower power first, then automatically switches to the one with greater power when the first runs out. Remaining battery power is displayed as a percentage on your camera’s LCD monitor.
The grip offers an extra shutter button, located at the low position, as well as front/back control dials and Auto Exposure Lock. All controls are placed appropriately for easy, comfortable access. A strap hole allows you to attach the optional STP-GB1AM Grip Belt. The buttons, dials, battery cover and connecting terminal on the grip are securely sealed for dust and moisture protection.
