This is the SONY VG-C4EM. It's a vertical grip compatible with the popular α1, α7 IV, α7RV, and the newly released α7 V on December 19th. It can hold two NP-FZ100 batteries, making it suitable for long shooting sessions. I'm selling it because I no longer need it after upgrading my camera. I didn't use it very often, so while there are some minor scratches, the condition is good as shown in the photos. The original box and instruction manual are included. Please see my profile for other important notes. Instant purchase is welcome. Product Description: Stamina Performance for Long Shooting Sessions By using two high-capacity Z series batteries continuously, you can achieve approximately twice the shooting time compared to using the camera body alone. At the same time, it maintains a compact and lightweight design that matches the camera body. Grip Shape with High Holding Performance The grip shape is the same as the camera body's grip, providing the same hold as horizontal shooting, even in vertical shooting. High Reliability and Rigidity as a System Designed with dust and moisture resistance equivalent to the camera body, ensuring high reliability as a system. Furthermore, it uses magnesium alloy to achieve high rigidity.
