Sony Releases Animal Eye AF Firmware Update for a6400 Camera

Sony has announced the release of a new firmware update for its a6400 Mirrorless Digital Camera. The Version 2.00 upgrade adds support for Animal Eye AF and compatibility with the RMT-P1BT wireless remote commander, along with general stability improvements.

The Animal Eye AF feature -- which we reviewed in full right HERE -- enables AI-driven animal eye detection via advanced subject recognition, allowing the camera to detect and track animal eyes. Dogs and cats are currently supported, but Sony plans to optimize the feature for more animals and add improvements to the mode's tracking performance in future updates. Animal Eye AF was also recently added to the company's a7 III and a7R III mirrorless cameras.

Here's a full rundown of Version 2.00 Firmware release notes and features per Sony:

  • Adds real-time Eye AF for animals
  • Detecting human and animal eyes simultaneously is not supported
  • Depending on the environment, animal type, and the movement of the animal, eye detection may not be possible
  • Refer to the Help Guide for additional information on updated functions
  • Adds support for the RMT-P1BT wireless remote commander (sold separately)
  • Improves the overall stability of the camera
