The BG-S7 Battery Grip for Sony a1, a9 II, a7 S III, a7R V, a7R IV, and a7 IV Series Cameras from Vello can be installed directly into the camera's battery chamber, just remove the camera's battery door, and store it conveniently inside grip's stem. Align the grip stem inside the camera battery chamber to ensure power is being supplied to the camera, then secure the grip to the body using the thumbscrew into the camera's 1/4"-20 tripod socket.

The BG-S7 includes a dual battery tray that accepts two NP-FZ100 rechargeable batteries, doubling the camera's battery life and shooting time. The grip offers a comfortable, extended, rubberized, nonslip grip, and an alternate shutter release button for vertical use. It also incorporates a secondary control set with front and rear dials, C1 and C2 function buttons, AF-ON and AEL buttons, and a Multi-Selector Joystick, so full camera functions are maintained while shooting vertically.

The grip includes a threaded 1/4"-20 socket on the base, making it compatible with tripods, quick release plates, L-brackets, and other accessories. The integrated strap mount allows a hand grip strap or shoulder strap to be securely attached.
