Repetitive patterns
Example: Skyscraper windows, computer keyboards, etc.
In such cases, do one of the following:

(2)Set the lens focus mode switch to <MF> and focus manually.
If an Extender (sold separately) is attached and the maximum aperture of the lens is f/5.6 or smaller (larger f/number), AF will not be possible (except Live mode AF). For details, see the Extender’s instruction manual.
For the cases AF can fail to achieve focus with Live mode AF, see page 106.
