Anticipating A9 6.0 Firmware since January, the update comes with two important upgrades: Animal Eye AF and an in-camera interval timer.
Animal eye tracking is an addition to the AI-powered tracking autofocus. Real-time Eye AF can be used simultaneously with tracking and the photographer may choose between human or animal. The best part: it works with silent shooting.
The other major feature is the addition of an in-camera interval timer for time-lapse, like the a6400. The update also allows the use of the wireless remote commander RMT-P1BT (sold separately).
