The autofocus performance of the a7 V is a key area of improvement over previous generations; borrowing from the flagship camera, the a7 V now sports an AI Processing Unit and refined subject detection and tracking. The phase-detection AF system itself still comprises 759 points, which cover about 94% of the sensor area, and support focusing down to -4 EV. Subject tracking and subject detection is improved, too, specifically how the camera is 30-50% faster to recognize animals and birds compared to the a7 IV.
