Driven by Sony's AI chip, it enhances autofocus tracking and adds features like pre-capture for up to one full second before shutter actuation. While retaining 8K video capabilities capped at 60fps, it serves as an iterative refresh that updates ergonomics and subject recognition over the original model.
