Predictive Focus Tracking

In AF-C mode or when continuous-servo autofocus is selected in AF-A mode, the camera will
initiate predictive focus tracking if the subject moves toward or away from the camera while
the shutter-release button is pressed halfway.

This allows the camera to track focus while

attempting to predict where the subject will be when the shutter is released.

Getting Good Results with Autofocus

Autofocus does not perform well under the conditions listed below. The shutter release may
be disabled if the camera is unable to focus under these conditions, or the in-focus indicator
(

I) may be displayed and the camera may sound a beep, allowing the shutter to be released

even when the subject is not in focus. In these cases, focus manually (

0 99) or use focus lock

(

0 97) 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
.

Example

: Subject is the

same color as the
background.

The focus point contains
areas of sharply contrasting
brightness
.

Example

: Subject is half in

the shade.

The focus point contains
objects at different
distances from the camera
.

Example

: Subject is inside a

cage.

Background objects appear
larger than the subject.

Example

: A building is in the

frame behind the subject.

The subject is dominated by
regular geometric patterns
.

Example

: Blinds or a row of

windows in a skyscraper.

The subject contains many
fine details
.

Example

: A field of flowers

or other subjects that are
small or lack variation in
brightness.
