Sony has officially released the latest firmware for its a9 full-frame mirrorless camera, bringing with it Real-Time Eye AF for animals, interval shooting and more.

Firmware version 6.00 makes good on Sony’s promise to bring Real-Time Eye AF for animals to its flagship mirrorless camera. As detailed previously when Sony launched Animal Eye AF on its a7R III and a7 III, the new mode will be available to select alongside Human Eye AF in the autofocus menu.

Only one of the modes can be selected at once and the Animal Eye AF will be slightly slower than Human Eye AF due to the increased processing power required, but the a9 shouldn’t have any problem keeping up. Sony has a detailed documentation page to read up on all of the intricacies of the Animal Eye AF mode.

The firmware update also includes built-in Interval Shooting, a feature we previously detailed with the a7R III and a7 III update:

Now, it's easy to capture between 1 and 9999 photographs in 1 to 60 second intervals. The new feature also includes an auto exposure (AE) sensitivity setting that can be adjusted between High, Mid or Low to account for changing exposures throughout the set capture time. The resulting images can also be put together into a full video using Sony's Imaging Edge app, which will process the Raw photographs and output the final video to YouTube, PlayMemories Online and other online video services.

Another addition is the ability to select the Focus Frame Color so it’s easier to see it in various environments, the ability to make the ‘My Menu’ appear when the menu button is pressed on the camera and support for Sony's RMT-P1BT Bluetooth Remote Commander. Bugs have also been addressed to smooth out the overall stability of the a9.

Firmware version 6.0 for the a9 is available for free on Sony’s support page for macOS (direct download) and Windows (direct download).
