α9に搭載された撮像エリア全体の約93%をカバーする693点像面位相差AFセンサーを搭載。(搭載了A9使用的覆蓋攝影範圍全體93%擁有693點相位差的自動對焦Sensor)
索尼自己的官方宣傳The innovative new α7 III full-frame mirrorless camera features a level of AF performance that has been largely improved over the α7 II, including the addition of 4D FOCUS™ capabilities. The new camera has 425 contrast AF points that work with a 693-point focal-plane phase-detection AF system inherited from the acclaimed α9 model. This innovative AF system covers approximately 93% of the frame, ensuring reliable focusing and tracking for even the most difficult to capture subjects.
至於吊不吊打,實機出了才知道
目前外國先行試用的專業攝影師都有極高評價,對焦速度跟A9分別不大
A9和A7III最大分別還是連拍張數和寫入速度,A9寫RAW可以241張,連拍20張/秒,而A7III連拍只有一半,RAW只有89張;AF/AE處理在細微部份估計也有差異,但目前資訊來看分別不是特別大
對焦系統上索尼自己的宣傳口徑就是A9同級,繼承自A9(AF system inherited from the acclaimed α9 model. )
