SSelecting the AF PointN

AF Operation and Maximum Lens AperturesWith 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 cross-type focusing (vertical and horizontal lines detected simultaneously) is possible with the center AF point. The center AF point is about twice as sensitive as the other AF points to detect vertical and horizontal lines.

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.
