Double the capacity and operation time with space for two long lasting NP-FZ100 batteries. A lightweight, compact magnesium alloy design matches the dust and moisture-resistant durability of the Alpha 7R IV. This ensures excellent performance while allowing the user to continue shooting in prolonged photo sessions, with no interruption. This Vertical Grip from Sony makes it easy to hold the camera and operate controls with nearly the same feel as when holding the camera horizontally. Space for two high-capacity NP-FZ100 batteries in the grip supply additional power that doubles the effective operating time, compared with the camera alone.
