If the Cross type sensor is so powerful, why does Canon still have out focus (跑焦) issues?
e.g. Like most people experience even using center point focus with the EF 50mm1.8.....(跑焦)
Does it mean if the system does not have out focus (跑焦) isuues, the cross type sensor is just a gimmick?
Thanks 大大 for your kind sharing in advance.

A700 的那張純粹只是表示他的中央點有兩個橫向、兩個縱向F4、一個橫向 F2.8 的 Sensor。事實上在AF Sensor 上的排列不會是這個樣子。這張圖純給人粹意會用。
Minolta Dynax7 那張就真的是 AF Sensor 上面的排列。有關 AF sensor 排列與對焦點的關係,可以參考這篇。
