BAT TERY GRIP
Designed for the
Sony Alpha a7 II Series
Mirrorless Cameras

Introduction
The Vello BG-S3-2 battery grip offers extended shooting
time and comfort when shooting in a vertical (portrait)
orientation. The grip is compatible with the Sony Alpha
a7 II series mirrorless cameras and accepts up to two Sony
NP-FW50 rechargeable batteries. It offers an alternate
shutter release button, AF/MF/AEL button, three custom
buttons, and front and rear dials, making the grip ideal for
shooting portrait photography. There is also a convenient
control-lock switch to prevent unwanted triggering of the
grip’s controls. And for connectivity, there is a mount on
the bottom for standard tripods, and a mount on the top
for hand straps.
