Sony has released firmware version 2.00 for its a6400 mirrorless camera, bringing with it Animal Eye AF, support for the RMT-P1BT wireless remote commander and other improvements to help with stability.
It’s been roughly two months since Sony launched firmware updates for its a7R III and a7 III, which brought with them, amongst other things, Sony’s new Animal Eye AF. Now, Sony has brought the system to its crop sensor mirrorless cameras.
As a refresher, Animal Eye AF is an autofocus mode that uses AI-trained algorithms to find and focus on the eyes of wild animals and pets. It works with AF-C focus mode and is activated when the shutter is half-pressed or when assigned to the AF-ON button.
As with the firmware updates for the a7R III and a7 III, Animal Eye AF can’t be used at the same time as Human Eye AF and, due to the extra processing power required to get the job done, it won’t be nearly as fast as the Human Eye AF. Sony has put together a full documentation page detailing the intricacies of Animal Eye AF.

Firmware version 2.00 has also added support for Sony’s RMT-P1BT wireless remote commander and a number of other bug fixes that improve the overall stability and functionality of the a6400.
Firmware version 2.00 can be downloaded from Sony UK’s website for macOS and Windows computers. Installation instructions can be found on the respective download pages.
