Getting Good Results with Autofocus

Autofocus does not perform well under the conditions listed below. If the camera is unable to focus

using autofocus, use manual focus (

32) or use focus lock ( 31) to focus on another subject at the

same distance and then recompose the photograph.

There is little or no contrast

between the subject and the

background

The focus area contains ob-

jects at diﬀ erent distances

from the camera

Example: Subject is the same color as the back-

ground.

Example: Subject is inside a cage.

The subject is dominated by

regular geometric patterns

The focus area contains areas

of sharply contrasting bright-

ness

Example: A row of windows in a skyscraper. Example: Subject is half in the shade.

The subject appears smaller

than the focus area

The subject many contains

ﬁ ne details

Example: Focus area contains both foreground

subject and distant buildings.

Example: A ﬁ eld of ﬂ owers or other subjects that

are small or lack variation in brightness.
