If you’re a filmmaker or a content creator, you’ll appreciate the dynamic range and color depth this camera offers.
Advanced Autofocus System
Sony has equipped the A7S IV with an advanced autofocus system that’s both fast and reliable. With 759 phase-detection AF points covering 92% of the frame, focusing is incredibly accurate, even in low-light scenarios. The real-time Eye AF works for both humans and animals, ensuring sharp focus on subjects in motion. This feature alone is a game-changer for wildlife and portrait photographers.
