S Selecting the AF PointN AF Operation and Maximum Lens Apertures With maximum apertures up to f/5.6: Cross-type focusing (vertical and horizontal lines detected simultaneously) is possible with all AF points. With certain lenses (see below), the off-center AF points will detect only vertical or horizontal lines (no cross-type focusing). With maximum apertures up to f/2.8: High-precision AF* with vertical and horizontal lines detection is possible with the center AF point, in addition to the cross-type focusing (vertical and horizontal lines detected simultaneously). The remaining eight AF points enable cross-type focusing in the same way as when using lenses with maximum apertures up to f/5.6. * Except with the EF28-80mm f/2.8-4L USM and EF50mm f/2.5 Compact Macro. If you use an Extender (sold separately) and the maximum aperture becomes smaller than f/5.6, AF shooting will not be possible (except in [u+Tracking], [FlexiZone - Multi], and [FlexiZone - Single] during Live View shooting). For details, refer to the Extender's instruction manual. Lenses not Enabling Cross-Type Focusing with all AF Points The following lenses enable only horizontal-line sensitive focusing with the three AF points on the left and the three AF points on the right and only vertical-line sensitive focusing with the top and bottom AF points. Cross-type focusing is possible only with the center AF point.
