Hi, I have a question about camera focus points. I'm interested about Wildlife and Sport photography, so if i set my camera to AI-Servo, can i tracking a subject with just 1 focus point? When im uses all focus point area, focus points are tracking the subject. With just 1 focus point can i do this? This only one focus stay unmoved on screen, points arent tracking? I need to press half camera shutter button and recompose and "track" with the camera like recomposing? Great respect, and im waiting for answers!
