Let’s talk about Sony’s new Real-Time Tracking Autofocus: A Breakthrough?
...Sony is going to keep iterating on this technology and improving it, as evidenced by what they did with Eye-AF to make it as good as it is today. From what we saw on the A9, which was in a very early beta version of the firmware, this is an extremely impressive first shot at "AI" autofocus from Sony, and strongly positions them as one of the early innovators, along with Olympus' first shot in the E-M1X. No one asked for this feature, but watch it become as popular and as demanded of a feature as Eye-AF has become as the years go by...
Sure, Sony has it for years
