If the camera can't detect a face, the autofocus system operates as it does when FlexiZone-Single mode is active. You also can press the Set button to display the FlexiZone-Single focus frame at any time. On occasion, you may need to set initial focus using the focus frame before the camera can detect a face. (This scenario can occur if the subject is seriously out of focus when you switch to the face-detection autofocusing mode.)

Quick mode autofocusing

As its name implies, Quick mode offers the fastest autofocusing during Live View or movie shooting — not so much in terms of the time it takes you to set things up, but in terms of how fast the camera can lock onto a focus target. In fact, Canon recommends that you use this mode when shooting with certain EF lenses; the list of affected lenses is provided in the camera manual. With those lenses, the other autofocus modes can be problematic.

In addition, this mode has one other benefit: It's based on the same nine-point focusing grid used for viewfinder photography, so it may feel more familiar to you than the other Live View and Movie mode AF methods. I labeled two of the nine focus points in the left screen in Figure 5-13. (The large rectangle in the center of the frame is not a focus point in this case; instead, it's used to magnify a portion of the subject to check focus. See the section “Zooming in for a focus check,” later in this chapter, for details.)

FIGURE 5-13: Quick AF Method offers nine focus points (left); to select which one you want to use, first activate the Quick Control screen and highlight the AF Quick option (right).
