The Sony XDCA-FS7 is a professional extension unit designed to expand the capabilities of the Sony PXW-FS7 and PXW-FS7 II cinema cameras. It adds advanced features such as 12-bit 4K and 2K RAW output, allowing filmmakers to capture higher-quality footage for demanding post-production workflows. The unit supports Apple ProRes 422 recording directly to the camera's XQD media, providing a convenient alternative to XAVC recording. Built-in Genlock and Timecode connections make it ideal for multi-camera productions, live events, and broadcast environments where precise synchronization is required. An integrated V-Mount battery plate and additional power outputs enable longer shooting times and support for professional accessories. By enhancing recording formats, power options, and connectivity, the XDCA-FS7 transforms the FS7 into a more versatile tool for cinema, television, and documentary production.
