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. 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 α7R IV body. As a result, the function, location and operational "feel", of the controls simulates those on the camera body, when the camera is held vertically. 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. 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.
