3 Customizing AF FunctionsN Selectable AF point You can change the number of manually selectable AF points. If 61point automatic selection AF is set, the Area AF frame (entire AF area) will be used for AF regardless of the setting below. : 61 points All AF points will be manually selectable. : Only cross-type AF points Only cross-type AF points will be manually selectable. The number of selectable cross-type AF points will differ depending on the lens. : 15 points Fifteen major AF points will be manually selectable. : 9 points Nine major AF points will be manually selectable. With a lens from Groups F to H (p.103-104), the number of manually selectable AF points will be fewer. Even with settings other than [61 points], AF point expansion (manual selection ), AF point expansion (manual selection, surrounding points) and Zone AF (manual selection of zone) are still possible. When you press the button, the AF points which are not manually selectable will not be displayed in the viewfinder. 124
