Sony Alpha A7S III - Firmware Update v5.0 Released

The firmware update v5.0 for the Sony a7S III introduces significant enhancements to focus control and versatility. The most notable addition is the Spot XL focus area and the ability to create three custom focus zones, both of which are fully integrated into the camera's tracking system. This allows videographers to maintain much higher precision in complex scenes by tailoring the focus area to the subject's exact dimensions, effectively minimizing autofocus hunting during critical shots. Regarding connectivity and file management, Sony has added native USB-C streaming support, enabling high-fidelity broadcasting without the need for external capture cards. The update also improves storage monitoring by displaying the remaining capacity of both memory cards simultaneously when using simultaneous or relay recording modes. Additionally, it introduces digital signature support for movie files, a security feature designed to certify footage authenticity and prevent manipulation in professional journalism. Finally, the user experience has been refined with a more flexible and accessible interface. The menus now feature an enlarged display option for easier reading, and the on-screen shooting information automatically reorients when switching to vertical shooting, optimizing the workflow for social media content. This version also fixes a critical audio bug where sound was being recorded even when the setting was turned off, while simultaneously improving overall system stability for demanding production environments.
