aperture
The variable diameter opening in a camera lens that lets you control the intensity of light reaching the
film or CCD. A camera's aperture and shutter speed determine a photo’s exposure. Aperture diameters are
expressed in f-numbers
−
the larger the f-number, the smaller the lens opening. Dividing the focal length
of a lens by a specific f-number gives its aperture diameter. See also “CCD” on page 116,“f-number” on
page 117, and “focal length” on page 117.
Aperture Priority (Av) exposure mode
The exposure mode setting in the Photo Assist menu that lets you select an aperture, and the camera
automatically selects the shutter speed. See also “aperture” on page 115, “exposure modes” on page 116,
“shutter” on page 121, and “Shutter Priority (Tv) exposure mode” on page 121.
Auto exposure mode
The exposure mode setting in the Photo Assist menu where all settings are at their defaults and cannot be
changed. See also “exposure modes” on page 116.
Auto Focus mode
The default focus mode of the camera that automatically focuses the camera lens on a picture subject.
You can change the focus mode to Manual Focus in the Photo Assist menu. See also “Manual Focus mode”
on page 119.
auto focus range
This focus range is set by pressing a status LCD button on top of the camera and determines whether
the focus is set for infinity (picture of a distant subject), for macro (a close-up picture of a subject), or for
normal focus range.
auto focus range button
A status LCD button on the top of the camera that you press to set the auto focus range.
auto focus range icon
An icon that appears in the status LCD and shows the camera’s current auto focus range.
automatic exposure (AE)
The camera feature that calculates the necessary shutter speed, aperture, and ISO speed to get the best
possible exposure.
automatic shutoff
A feature that automatically shuts off the camera after a certain period in order to preserve battery power.
Av
See “Aperture Priority (Av) exposure mode” on page 115.
battery status
The amount of power that remains in the battery.
