The Documentary Dock from Sony is an EFP/ENG-style build-up kit which enables you to expand your PMW-F5 or PMW-F55 camcorder into an EFP/ENG camcorder. This system is designed for a single operator and provides conventional EFP/ENG operation similar to that of Sony XDCAM series camcorders. The documentary dock has an ergonomic design and features an adjustable shoulder pad and front block control.
