Sony XDCA-FX9 Extension Unit PXW-FX9 Camera

The Sony XDCA-FX9 Extension Unit is a dedicated accessory module designed to expand the capabilities of Sony's PXW-FX9 full-frame camcorder. Its headline feature is 16-bit RAW output, which allows the FX9 to send uncompressed RAW video data to compatible external recorders such as the AXS-R7. This gives cinematographers and colorists maximum latitude in post-production, preserving the full dynamic range and color depth captured by the FX9's full-frame sensor. For productions that demand the highest image quality—feature films, commercials, and premium episodic content—this RAW capability elevates the FX9 from a versatile documentary camera to a viable cinema production tool.

Beyond RAW output, the XDCA-FX9 addresses practical production needs. The V-shoe battery mount accepts industry-standard V-mount batteries, providing substantially longer runtimes than the camera's built-in battery system and enabling all-day shooting without interruption. D-Tap and 4-pin Hirose power outputs allow operators to run monitors, wireless video transmitters, and other accessories directly from the V-mount battery. The integrated slot-in bay accepts Sony DWX and UWP wireless audio receiver modules, eliminating the need for externally mounted wireless receivers and reducing cable clutter on the camera rig. A wired LAN interface and two USB ports round out the connectivity options, supporting remote camera control and high-speed data transfer. At 6.19 × 5.37 × 6.98 inches and 4.49 pounds, the unit adds noticeable size and weight to the FX9 but integrates cleanly with the camera body's design.
