The Battery Grip for Sony A7/A7R/A7S series (model BG-S7) is a professional-grade battery grip accessory engineered to extend your Sony mirrorless camera’s performance and shooting comfort. Accepting two NP-FZ100 rechargeable batteries simultaneously, it effectively doubles your battery life — keeping you shooting longer during weddings, events, or extended outdoor sessions with compatible bodies including the Sony a1, a9 II, a7S III, a7R V, a7R IV, and a7 IV.
Designed for serious photographers who shoot in portrait orientation, this grip features a full secondary control set — including a dedicated shutter release, front and rear dials, C1 and C2 function buttons, AF-ON, AEL, and a Multi-Selector Joystick — so you never lose access to critical camera functions when composing vertically. A rubberized nonslip grip, a base-mounted 1/4″-20 tripod socket, and an integrated strap mount round out this essential Sony accessory.
