Sony has announced that a firmware update is now available for the a6400 mirrorless camera.


Firmware update version 2.00 offers the following improvments:

  • Adds real-time Eye AF for animals *
  • Allows the operation with the wireless remote commander RMT-P1BT (sold separately)
  • Improves the overall stability of the camera

*It is not possible to detect simultaneously human and animal eyes. Eye detection may not be possible depending on the environment, animal type or the movement of the animal. Please see the Support site for details.

The Eye AF for animals mode utilises Sony’s latest algorithm including Artificial Intelligence based object recognition and processes colour, subject distance (depth), pattern (brightness) as spatial information to ensure that all subjects can be captured with excellent accuracy.

Plus, when photographing or videoing humans, face and eye position information is recognised by AI and the subjects eye is monitored in real time with extremely high tracking precision. This can be activated by a simple half press of the shutter button, or can be assigned to a custom function as well.

The update is available for Windows PCs from the Sony website
