In April of this year, the Animal Eye AF feature was added to the firmware update in the a7R III and a7 III cameras. She uses artificial intelligence algorithms to find and monitor wild and pet eyes in the frame.

The function is available in the AF-C focus mode and activated when the shutter button is pressed halfway, or the AF focus is programmed on the AF-ON button, and it is pressed. It can be used simultaneously with Human Eye AF, and due to the additional computing power required to perform the job, it works a bit slower than Human Eye AF.

Also, the update adds support for the RMT-P1BT wireless remote control and other improvements, in particular, "enhanced stability of the device."
