This camera uses Real-time Eye AF when recording videos, and the new "anti-flicker" mode auto-adjusts for the presence of artificial lights. Plus, it's slightly bigger with a deeper grip like the Sony a7R IV compared to its predecessor. It has an additional USB Type-C port. The battery life is sufficient for 690 shots. The Wi-Fi supports a faster 5 GHz ac band.
