Vega R3 also introduces innovative functions like 'Best Face', voice recognition, continuous recording, and trackingfocus so that it can reliably substitute a regular digital camera.
It has improved focustracking, so if you're autofocusing something that's moving, all of the sensors can concert with one another and track the subject better.
With Canon's Hybrid CMOS AF System and Movie Servo AF, the camera provides continuous AF for focustracking of moving subjects by helping to reduce the camera's need to "hunt", resulting in a quick and smooth continuous AF.
