請教各位師兄：
相機已設定為3D 51點追蹤對焦、連續對焦、動態 AF。發現打雀時對焦點不斷移動 (對焦點並非全落於主體上)，而主體實際上並未移動。曾嘗試先選對焦點才半按快門，但情況都是一樣。
謝謝！

The background color might be too similar to the subject color that's why the 3D autofocus will encounter problem locking on the bird... this is one reason i could think of....

請安主(af L)試試

First of all, the AF delay time must be set to 0 (default time is 6s) then the focus mode is set to continuous mode plus 3D 51 points AF mode. The focus point is tracing the subject at the nearest point.

When you shoot a subject, you must press the shutter bottom down until the shooting is finished.

Thank you CHing, rick999999 & Iireskii. I will try in this week again.
