When AI Servo AF mode is set with 65-point automatic selection AF,
Large Zone AF (manual selection of zone), or Zone AF (manual selection
of zone), the active AF point <S> will keep switching to track the
subject. However, under certain shooting conditions (such as when the
subject is small), it may not be able to track the subject. Also, in low
temperatures, the tracking response may become slower.
With Single-point Spot AF (manual selection), focusing with the
Speedlite’s AF-assist beam may be difficult.
If a peripheral AF point or a wide-angle lens is used, achieving focus may
be difficult with an EOS-dedicated, external Speedlite’s AF-assist beam.
In such a case, use an AF point closer to the center.
When the AF point(s) light up, part or all of the viewfinder may light up in
red. This is a characteristic of AF point display (using liquid crystal).
In low temperatures, the AF point’s display may be difficult to see. This is
a characteristic of AF point display (using liquid crystal).
With [24: Orientation linked AF point], you can set the AF area
selection mode + AF point (or only the AF point) separately for the
horizontal and vertical orientations (p.125).
With [24: Selectable AF point], you can change the number of
manually selectable AF points (p.123).
