A new firmware update has arrived for the Sony A7 IV, adding new features and quality-of-life improvements.

Of course, with Sony's last two firmware updates (one for the FX30 and the other for the A7R V) having to be suspended due to potential issues, there may be some hesitation among users about installing this new release right away.

Still, if you're feeling brave, firmware Ver. 4.00 offers some worthwhile functionality. The full release notes are as follows:
