Focusing Depth of Field and Focus Tracking Your camera is equipped with autofocus where focusing is automatically executed. Basics of the relationship between focus, depth of field, and Focus Tracking are explained in this section. Depth of Field When focusing, depth of field should be considered. Depth of field is the zone of sharpest focus in front of and behind the subject on which the lens is focused. Depth of field varies according to shooting distance, focal length, and especially aperture. Smaller apertures (larger f-numbers) produce a deeper depth of field where the background and foreground become sharper. Larger apertures (smaller f-numbers) produce a shallower depth of field where the background becomes blurred. Similarly, shorter shooting distance or longer focal length produce a shallower depth of field, and longer shooting distance or shorter focal length produce a deeper depth of field. Note that depth of field tends to be shallower in front of the subject in focus and deeper behind the subject. NOTE: You can confirm the depth of field with the Depth of Field Preview button (see page 2-20). Focus Tracking Your camera automatically switches to focus tracking when a moving subject is detected under the following conditions: • The Focus Mode selector is set to Single Servo AF (S) or Continuous Servo AF (C) and you lightly press the Shutter Release button. • You lightly press the Shutter Release button or press and hold when the AE--L/AF-L Button Custom Setting is set to Start (see page 5-2). Focus tracking lets the camera analyze the speed of the moving subject and obtain correct focus by anticipating the subject's position and driving the lens to that position at the exact moment of exposure. In Single Servo AF, Focus Tracking is activated with a subject that has been moving before the focus detection. Focus locks when the subject stops moving and the focus mode indicator appears in the viewfinder. In Continuous Servo AF, the camera continues to track the subject and focus is not locked. Tracking occurs even if a subject starts moving in the middle of focus detection. 8-10 April 29, 2004

Focusing

Depth of Field and Focus Tracking

Your camera is equipped with autofocus where focusing is automatically

executed. Basics of the relationship between focus, depth of field, and

Focus Tracking are explained in this section.

Depth of Field

When focusing, depth of field should be considered. Depth of field is the

zone of sharpest focus in front of and behind the subject on which the lens

is focused. Depth of field varies according to shooting distance, focal

length, and especially aperture.

Smaller apertures (larger f-numbers) produce a deeper depth of field

where the background and foreground become sharper. Larger apertures

(smaller f-numbers) produce a shallower depth of field where the

background becomes blurred.

Similarly, shorter shooting distance or longer focal length produce a

shallower depth of field, and longer shooting distance or shorter focal

length produce a deeper depth of field. Note that depth of field tends to be

shallower in front of the subject in focus and deeper behind the subject.

NOTE:

You can confirm the depth of field with the Depth of Field Preview

button (see

page 2-20

Focus Tracking

Your camera automatically switches to focus tracking when a moving

subject is detected under the following conditions:

•

The Focus Mode selector is set to Single Servo AF (

) or Continuous

Servo AF (

) and you lightly press the Shutter Release button.

•

You lightly press the Shutter Release button or press and hold

when the AE--L/AF-L Button Custom Setting is set to Start (see

page 5-2

Focus tracking lets the camera analyze the speed of the moving subject and

obtain correct focus by anticipating the subject’s position and driving the

lens to that position at the exact moment of exposure.

In Single Servo AF, Focus Tracking is activated with a subject that has been

moving before the focus detection. Focus locks when the subject stops

moving and the focus mode indicator

appears in the viewfinder.

In Continuous Servo AF, the camera continues to track the subject and

focus is not locked. Tracking occurs even if a subject starts moving in the

middle of focus detection.
