72 Although this is the same as Single-point AF, the selected AF point covers a smaller area to focus. Effective for pinpoint focusing of overlapping subjects such as an animal in a cage. Since Spot AF covers a very small area, focusing may be difficult during han d-held shooting or for a moving subject. Select one AF point < S> to be used for focusing. The manually-selected AF point < S> and adjacent AF points < w> (above, below, on the left and on the right) are used to focus. Effective when it...

73 AF Area Selection Modes The manually-selected AF point and adjacent AF points < w> are used to focus. The AF point expans ion is larger than with AF point expansion (Manual selection ), so the focusing is executed over a wider area. Effective when it is difficult to track a moving subject with just one AF point. AI Servo AF and One-Shot AF work in the same way as with AF point expansion (Manual selection ) mode (p.72). The 61 AF points are divided into nine zones for focusing. All the AF...
