Custom Function Settings

Remarks

Even if the exposure settings you have set are not suitable, the camera will automatically alter the settings to obtain a standard exposure. This feature is convenient when the scene’s brightness changes suddenly.

This setting is suited for subjects whose focusing distance changes irregularly.

The focusing point selection range expands by one point all around the manually-selected focusing point. This setting is effective when the manually-selected focusing point is unable to focus track a subject moving irregularly.

As shown in the table below, the camera sets the focusing point selection range automatically to suit the lens focal length, AF mode, and subject movement during predictive AF. This feature is useful when the subject movement is unpredictable.
