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 :wink:

On the A6400:

Sony A6400 Review

Let’s all take a close look at the focusing capability of the Sony A6400 :

Though extremely impressive as a technology concept and it's use in the high-end A9 was laudable, the experience on the lower-end A6400 wasn't quite as rosy. With considerably less processing power and a slower sensor read speed, the A6400 struggled to offer the same experience as the A9 in practice, despite the expectations set by the public Sony marketing presentation. Don't get us wrong, it's still quite good for an entry-level camera (if you consider $1000 entry-level), but it's obvious there are certain hardware requirements necessary for truly excellent implementation that are lacking in the A6400.
