P, S, A, and M Modes

P, S, A, and M modes offer control over a variety of advanced settings, including exposure (

45), white balance, and image optimization. Each of these modes offers a different degree

of control over shutter speed and aperture:

Mode Description

Programmed auto

( 40)

Camera sets shutter speed and aperture for optimal exposure. Recom-

mended for snapshots and in other situations in which there is little time to

adjust camera settings.

Shutter-priority

auto ( 41)

User chooses shutter speed; camera selects aperture for best results. Use to

freeze or blur motion.

Aperture-priority

auto ( 42)

User chooses aperture; camera selects shutter speed for best results. Use to

blur background or bring both foreground and background into focus.

M Manual ( 43)

User controls both shutter speed and aperture. Set shutter speed to “bulb”

or “--” for long time-exposures.

Lens Aperture Ring

When using a CPU lens equipped with an aperture ring, lock the aperture ring at the minimum aperture

(highest f/-number). Type G lenses are not equipped with an aperture ring.

Non-CPU lenses can only be used in exposure mode M, when aperture can be adjusted manually using

the lens aperture ring (in other modes, the shutter-release will be disabled). The camera exposure

meter and a variety of other features can not be used ( 97).

10—ISO Auto ( 76)

Use this option to enable auto ISO sensitivity control in P, S, A, and M modes.

Shutter Speed and Aperture

The same exposure can be achieved with different combinations of shutter speed and aperture,

allowing you to freeze or blur motion and control depth of field. The following figure shows how

shutter speed and aperture affect exposure.

Shutter speed Aperture

Fast shutter speed Small aperture (large f-/number)

Slow shutter speed Large aperture (small f/-number)

1 2 ... 41 42 43 44 45 46 47 48 49 50 51 ... 138 139
