AF Area Selection Modes

With lenses whose maximum aperture is larger than f/5.6

With all AF points, cross-type AF sensitive to both vertical and horizontal lines

is possible. With the following lenses, the peripheral AF points will be vertical-

line or horizontal-line sensitive only. (They will not work as cross-type points.)

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 18 AF points will work as cross-type points with lenses

brighter than f/5.6.

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

Lens’ Maximum Aperture and AF Sensitivity

If [8C.Fn III -12: Orientation linked AF point] is set to [1: Select

different AF points], you can set the AF area selection mode and

manually-selected AF point (or zone in the case of Zone AF) separately

for vertical and horizontal shooting (p.230).

If [8C.Fn III -10: Focus display in AI SERVO/MF] is set to [Disable],

the active AF points <S> during AI Servo AF will not be displayed.
