Firmware version v2.00 has now been released for the Sony a6400. This firmware update adds real-time Eye AF for animals (my setup guide), support for the RMT-P1BT wireless remote commander (my setup and user guide), as well as improving the overall stability of the a6400.
Sony a6400 Forum & Facebook Group
If you are looking for further help and advice on the a6400 or would simply like to share your photos and videos, then please head over to our friendly Sony a6400 Forum. If you prefer Facebook then I also run the Sony a6400 Shooters Group.
You can download firmware v2.00 from the following Sony support sites:
US: Sony a6400 Support Site
UK: Sony a6400 Support Site
Make sure you follow the install guide tips on the download page, especially for Mac computers as it’s not so simple. I’d recommend navigating to your local Sony support site if your native language is not English. Also it’s best to use the micro usb cable that came with the a6400 for the update.
If you are struggling with installing it on your Mac then Jason Vong’s YouTube Video is also helpful.
For help on using Animal Eye AF please refer to the relevant section in the a6400 online help guide.
Once you have installed the firmware update you might find my following Animal Eye AF setup guide helpful:
One small tip: To detect animal eyes, arrange the composition so that both eyes and the nose of the animal are within the angle of view. It does work sometimes with just one eye in view, but works better with two. It also works best on animals with cat and dog like faces, don’t expect it to work well on birds.
