F6: 11-area Wide-Area AF with 9 cross-type sensors (Multi-CAM2000 AF module)
1V: Each of the 45 focusing points within the Area AF is composed of horizontal line detection sensors. These sensors operate with EF lenses having a maximum aperture of f/5.6 or larger. They are particularly well-suited to focusing on moving subjects. The central seven points of the Area AF sensor also incorporate vertical line detection sensors, six of which operate with EF lenses with maximum apertures of f/2.8 or larger and theoretically provide focusing precision three times as high as the vertical sensors.
市面上所有廠牌的全部DSLR機種, 能比的上這兩台"傳統單眼"對焦系統的, 屈指可數咧~

註1: 以上資訊摘自兩家的美國官方網站. 英文總比日文好懂一些~

註2: 另一部傳統單眼的旗艦 Leica R9.....嗯, 啊, 手動對焦體會萊卡工藝, 無處不是對焦點
