Changing the Focusing Method
Shooting conditions that make focusing difficult
Low-contrast subjects such as the blue sky, solid-color flat surfaces or
when highlights or shadow details are lost.
Extremely bright or dark subjects.
Stripes and other patterns where there is contrast only in the horizontal
direction.
Subjects with repetitive patterns (skyscraper windows, computer
keyboards, etc.).
Fine lines and subject outlines.
Under a light source whose brightness, color, or pattern keeps changing.
Night scenes or points of light.
When the image flickers under fluorescent or LED light sources.
Extremely small subjects.
Subjects at the edge of the picture.
Subjects strongly reflecting light.
The AF point covers both a near and faraway subject (such as an animal in
a cage).
Subjects that keep moving within the AF point and cannot keep still due to
camera shake or subject blur.
Autofocusing while the subject is very far out of focus.
Soft focus effect is applied with a soft focus lens.
A special effect filter is used.
In the above cases, if the camera cannot focus automatically, focus manually.
With some EF lenses (Mount Adapter EF-EOS M required), it may take longer
to achieve focus or correct focus may not be achieved. For the latest
information, visit your local Canon Web site.
