Sony VG-C4EM Vertical Grip. Used in mint - like new condition. Please look at photos. I forgot to take photo of bottom of the grip, but it's absolutely clean. Key Features For Select Sony Mirrorless Cameras Holds One or Two NP-FZ100 Batteries Extended Grip for Vertical Shooting Second Shutter Button and Multi-Selector USB Charging via Camera Body Weather-Sealed Magnesium Alloy Design Dedicated to the Sony Alpha 1, a7 IV, a7R IV, a7S III, and a9 II mirrorless cameras, this VG-C4EM Vertical Grip offers both extended battery and a more comfortable grip when shooting in the vertical orientation. The grip accepts either one or two NP-FZ100 batteries to increase the effective battery life for longer shooting sessions, and the batteries can be charged in the grip while attached to the camera via the body's USB port. The grip's design maintains the same layout as the camera body itself, and includes a secondary shutter button and Multi-Selector for intuitive use. The grip is built from magnesium alloy and is dust and moisture resistant to match the weather-sealing of the camera itself.
