Sony has just released the firmware update for the Sony a6400 adding real-time Eye AF for animals. Sony’s Eye AF for animals feature has already been added for the Sony A7 III, A7R III in the latest firmware update back in April. This feature has still not yet been added to the A9 but is due in the 6.0 release in Summer 2019.
Currently, it works with cats & dogs, but Sony is working on adding more animal recognition including birds in flight. While it may seem like a trivial thing right now, once they have added birds in flight, it should be a popular choice for wildlife & bird photographers. Especially for those wanting to use the newly announced 600mm super-telephoto lenses, as it is already difficult enough to track a bird, yet keep the focus on the eyes.
You can download the firmware update from the Sony website and requires the camera to be connected to a computer to install.
The Sony a6400 retails for USD $898.
