看完這篇,大概就可冷靜一下! 7D test Continuous focus using Zone AF, nine points in the centre, AI Servo and the EF 200mm f/2L IS, tracking a running dog in fading light, the results were terrible. Over about 80 frames the camera got almost nothing usably in focus. If this result is representative of Zone AF, then Zone AF will be the way wrong choice for fast-moving subjects. We had better luck tracking the dog with Spot AF.
