dpreview原文：
10:32AM: a6400 has the a9's Bionz X processor and has all of the real-time AF tracking that the a9 will receive in its firmware upgrade. The top burst rate with continuous AF is 11 fps.
也就是说最新的对焦系统Speed x AI.目前来看只有A6400和之后会升级的A9会有。
这个系统视频中也很好用！
用过A63/6500的朋友知道现在的视频AF水平吧……
10:22AM: Works in video, too. Eye AF always on. You can select left/right or automatic Eye AF.
900刀比A6300首发便宜100刀，还是很香的，不过估计我会买A7000
