This Wooden Camera V-Mount Plate allows you to connect V-mount batteries to your Sony A7, A7r, or A7s. It connects to the camera via a dummy battery, which extends out from the side on a 16" cable, and an integrated regulator ensures that the correct voltage is delivered to the camera. The plate also features two P-Tap accessory ports providing 12V-16V of power (depending on your battery).
This plate is designed to be mounted on your rig using Wooden Camera's Battery Slide mounting adapter, sold separately, but it can also be mounted in any of the other ways that standard V-mount plates can be mounted.
