The update also added support for continuous shooting at approximately 120 fps with the Sony α9 III under specific focus-mode conditions: AF-S, DMF or MF.

These improvements are retained as part of the lens’s firmware history, making it worthwhile for users with older firmware to update to the latest available version.
