The battery grip for Sony Alpha 1 / 7S III / 7R V / 7R IV / 7 IV / 9 II cameras with E mount offers operational controls almost the same as those on the camera body. Position, size and shape of the buttons are optimized using the same body material as the α9 II and α7R IV. As a result, when you hold the camera vertically, function, position and operational “feel” of the controls mimic those of the camera body. can hold one or two NP-FZ100 batteries. When you use two batteries, the camera can operate up to twice as long as when you use only one. You can recharge the batteries in the vertical grip via the USB port on the camera itself, without detaching the grip. For extended shooting sessions, you can directly provide extra power to the camera via the camera’s USB port by using a portable battery or AC adapter to supplement battery power.
