On March 30 2022 Sony released the version 1.01 firmware for the A7IV full frame camera. The benefits of the firmware release are listed as "Improves the accuracy of the Eye AF feature", "Fixes an issue where you may not be able to take photos when using a SEL2860 lens", and the obligatory "Improves the operational stability of the camera".
As an owner of the Sony A7IV since the very first day of public availability, my experience has been nothing less than amazing when using this camera in a wide range of critically demanding professional photography and video environments.
In this video, I give a basic comparison and demonstration of situations using the Eye AF feature with Human, Animal, and Bird subject selection, with both the original v1.00 firmware, and the new v1.01 firmware.
