When Autofocus Fails

The camera has a high-precision AF system which can focus almost all

subjects. However, it can fail to achieve focus (the in-focus indicator blinks)
the subjects listed below.

Difficult Subjects for Autofocusing

• Low-contrast subjects. Example: Blue sky. flat surface with a solid color.

• Subjects in very low light.

• Extremely backlit or reflective subjects. Example; Automobile with a

highly reflective finish.

• Overlapping near and far objects. Example: Animal behind bars in a cage.

In such cases, use one of the following methods to focus:

(1) Focus lock an object at the same distance as the subject and

recompose.

(2) Set the lens focus mode switch to <MF> or <M> and focus manually as

explained below.

0 If focus cannot be achieved even with the EOS-dedicated Speedlite's AF-assist

light, select the center focusing point instead of an off-center focusing point.

(SQ Manual Focusing

Set the lens focus mode switch to

<MF> (or <M> on older lenses).

The <C5iQ> icon will be displayed on
the LCD panel.

subject is in focus in the viewfinder.

focusing point(s) achieving focus will flash in the viewfinder and the in-focus

indicator <•> will also light.
