Mode Description

aperture for optimal exposure. Recommended for snapshots
and in other situations in which there is little time to adjust
camera settings.
S
Shutter-priority auto (0 74): User chooses shutter speed; camera
selects aperture for best results. Use to freeze or blur motion.
A
Aperture-priority auto (0 75): User chooses aperture; camera
selects shutter speed for best results. Use to blur background
or bring both foreground and background into focus.
M
Manual (0 76): User controls both shutter speed and aperture.
Set shutter speed to Bulb (A) or Time (%) for long time-
exposures.
A Lens Types
When using a CPU lens equipped with an aperture ring (0 280), lock
the aperture ring at the minimum aperture (highest f-number). Type G
and E lenses are not equipped with an aperture ring.
Non-CPU lenses can only be used in mode M (manual), when aperture
can only be adjusted using the lens aperture ring. Selecting any other
mode disables the shutter release. For more information, see
“Compatible Lenses” (0 279).
