The Sony VG-C4EM Battery Grip is a vertical battery grip for Sony's a7R IV and a9 II mirrorless cameras.

Easy operation in vertical orientation

The VG-C4EM provides operational controls nearly the same as those of the camera body. The location, size, and shape of buttons are optimised, using the same material used on the α9 II and α7R IV bodies. As a result, the function, location and operational "feel", of the controls simulates those on the camera body, when the camera is held vertically.

Firm and secure grip

The ingenious design of the grip lets you hold the camera firmly. The Vertical Grip allows you to shoot photos easily and enjoyably regardless of whether you hold the camera horizontally or vertically, making it easier to concentrate on the subject and composition.

Effective operating duration doubled

The VG-C4EM can hold one or two NP-FZ100 batteries. When using two batteries, the camera will operate for nearly twice as long as when using one battery. Remaining battery power is indicated on the LCD screen, in 1% increments. When one battery expires, the camera automatically switches to the other, allowing continuous operation.

Reliable dust/moisture-resistance

The camera-grip attachment features the same sealing material used on the camera body, to keep out dust and moisture. This improves the overall reliability of the camera system.

Recharge batteries or supply power via USB

Batteries in the vertical grip can be recharged via the camera’s USB port, without detaching the grip from the camera. For extended shooting sessions, extra power can be supplied direct to the camera via the camera’s USB port using a mobile battery or AC adaptor to supplement battery power.

Light yet durable magnesium alloy body

The exterior of the VG-C4EM is made of the same magnesium alloy that is used in the α9 II and α7R IV bodies, to provide the same rigidity as the cameras themselves yet keep the overall weight and bulk to a minimum.
