S Selecting the AF PointN

With lenses whose maximum aperture is larger than f/5.6

With the center AF point, cross-type AF (sensitive to both vertical and

horizontal lines) is possible. The remaining eight AF points are

horizontal-line sensitive or vertical-line sensitive.

With lenses whose maximum aperture is larger than f/2.8

With the center AF point, high-precision, cross-type AF sensitive to both

vertical and horizontal lines is possible. The center AF point’s sensitivity

to vertical and horizontal lines is about twice as sensitive as the other

AF points. The remaining eight AF points are horizontal-line sensitive or

vertical-line sensitive.

* Except with the EF28-80mm f/2.8-4L USM and EF50mm f/2.5 Compact Macro

lenses.

displayed like normal AF points. They function as

follows:

: Vertical-line sensitive with f/2.8 and f/5.6

lenses, as with the center AF point.
