The VG-C2EM Battery Grip from Jupio is designed for the Sony Alpha a7 II, a7R II, and a7S II Cameras. It holds up to two NP-FW50 battery packs, effectively doubling your shooting time, while providing increased comfort, stability, and control when shooting in vertical and landscape positions. A heavy-duty wheel lets you lock the unit tightly to the camera, and this ergonomically-designed grip also features a shutter release button.
