Some subjects may be easier to track with the Group-area mode. This mode also provides continuous autofocusing. But rather than favoring a single focus point, the camera considers a cluster of five focus points and locks focus on the closest object that falls under one of those points. Before initiating autofocusing, use the Multi Selector to move the focus points over your subject. (Four points appear in the viewfinder; the fifth, in the center of the group, is invisible.)

Going back to the marching band scenario, you might use Group-area mode if your subject is the drum major rather than a musician. (If you aren’t a band geek like me, the drum major is the person leading the band down the street — usually wearing a tall hat shaped like Marge Simpson’s hairdo.) Assuming that you’re shooting at an angle that has the band coming towards you, the fact that Group-area mode targets the closest object should make it easy to lock focus on the drum major.

Remember, too, that if you pair Group-area mode with the AF-S Focus mode, the autofocusing system incorporates face detection into the mix. If the portion of the scene under the five-point grid contains a face, that face is used as the focusing target, regardless of whether another object is closer to the camera. Face detection usually works only when the subject is facing directly into the camera, however, and probably won’t be successful if the eyes are shaded by the brim of a Simpsonesque hat.
