3 Customizing AF Functions : Select separate AF points The AF area selection mode and manually-selected AF point (or Zone) can be set separately for each camera orientation (1. Horizontal, 2. Vertical with the camera grip at the top, 3. Vertical with the camera grip at the bottom). Convenient when, for instance, you want to keep using the right AF point during all camera orientations. When you manually select the AF area selection mode and AF point (or Zone with Zone AF) for each of the three camera orientations, they will be set for the respective orientation. Whenever you change the camera orientation, the camera will switch to the AF area selection mode and manually-selected AF point (or Zone) set for that orientation. If you clear the camera settings to their defaults (p.58), the setting will be [Same for both vert/horiz]. Also, your settings for the three camera orientations will be cleared and all settings will revert to Single-point AF (Manual selection) with the center AF point selected. 25 Manual AF point selection pattern During manual AF point selection, the selection can either stop at the outer edge of the area AF frame or it can move to the opposite AF point. This function works in AF area selection modes other than 61-point automatic selection AF and Zone AF. (It takes effect in 61-point automatic selection AF only with AI Servo AF.) : Stops at AF area edges Convenient if you often use an AF point along the edge. : Continuous Instead of stopping at the outer edge, the selected AF point continues to the opposite side of the area AF frame. 100
