Tether Tools Relay Camera Coupler CRSFW50 for Sony Battery NP-FW50

The optional Blackmagic Pocket Battery Grip lets you replace the camera’s standard LP‑E6 battery with two L‑series batteries so you can shoot for over 2 hours on a single charge! That’s a massive battery life, in a design that integrates with the camera itself and can be used as a single unit. Featuring a unique carbon fiber design, non‑slip hand grips, and a slide out tray that holds 2 L‑series batteries, the Pocket Battery Grip also makes it easier to hold the camera on longer shoots because it increases the grip area of the handle. You can also charge the batteries in the grip via the camera’s 12V DC power connection in between takes!
