Firmware Friday: Sony A6400 gets real-time animal eye AF and more


posted Friday, June 14, 2019 at 10:00 PM EDT


This week's Firmware Friday roundup is uncommonly brief, with just one new firmware update appearing on the scene in the past seven days. It's Sony which sails to the rescue with a significant firmware update for its A6400 mirrorless camera, at least if you're a pet owner or like to take pictures of animals.

As of the newly-released firmware version 2.00 (download here for Windows or here for Mac), the A6400 becomes the fourth Sony model after the A7 III, A7R III and A9 to get the company's Real-time Eye AF for Animals feature. The company doesn't say which specific animals that the system can detect, even in the newly-updated online product manual, but has shown domestic cats, dogs and other related species such as lions and foxes in promotional materials for the feature, such as the video below.

As well as adding the Animal Eye AF feature, which incidentally cannot function at the same time as human face / eye-detection, Sony has also gifted the A6400 with support for the separately-available RMT-P1BT wireless remote commander. And Sony says it has improved overall stability of the camera too, although it doesn't specify in what respect(s) these improvements were made.

And that's all for this week. Be sure to check back next time for more firmware news!
