aperture automatically to suit the subject brightness.
A fast shutter speed can freeze motion, and a slow shutter speed can
achieve a blurred effect.

●Shutter speed
The shutter speed is the length of time the camera’s shutter opens to\
expose the film to the light coming through the lens. The shutter speed
displayed on the camera’s LCD panel and in the viewfinder ranges from\
30 sec. to 1/8000 sec. and bulb.

•If the lens’ maximum aperture (smallest F-number like
f/1.4) blinks, it indicates underexposure. Turn the < >
dial to set a slower shutter speed until the aperture stops
blinking.
• If the lens’ minimum aperture (largest F-number like f/22)
blinks, it indicates overexposure. Turn the < > dial to
set a faster shutter speed until the aperture stops
blinking.

If a standard exposure cannot be obtained in the shutter speed-priority \

slower shutter speed. This feature is called safety shift.
Custom Function CF-6 enables the shutter speed to be set in full-stop or\
 half-stop
increments instead of the standard 1/3-stop increments. See page 112.CF

							2. Aperture-Priority AE (Av): Yo u   Set the Aperture
In this mode, you set the desired aperture and the camera sets the
shutter speed automatically to suit the subject brightness.
The larger the aperture (smaller F-number like f/1.4) the more blurred\
 the
background will be. This effect is suited for portraits. The smaller the\
aperture (larger F-number like f/22), the clearer the focus will be fo\
r both
near and far objects.

							●Aperture
The aperture (or F-number) indicates
the size of the aperture opening in the
lens. The aperture displayed on the
camera’s LCD panel and in the
viewfinder can range anywhere from
1.0 to 91, depending on the lens
attached to the camera. The larger the
F-number, the smaller the aperture.
And the smaller the F-number, the
larger the aperture.

•As long as the shutter speed is not

• If the shutter speed is less than the
reciprocal of the lens focal length (i.e.
1/200 for a 200mm lens), camera shake
may cause a blurred picture.

3. Depth-of-field AE (DEP): 
You Set the Depth of Field
This mode is for obtaining sharp focus between a specified point in the
foreground and one in the background. It is effective for large-group
photos and landscapes. The optimum point of focus and aperture to attain\
the depth of field are set automatically along with the shutter speed. Y\
ou
can use this mode with a manually-selected or eye-selected focusing
point.
• To use this mode, the lens focus mode switch must be set to AF.

Depth-of-field AE with a Camera-Selected Focusing Point
• The camera selects the center focusing point for depth-of-field AE. Foll\
ow the
same procedure as for “Depth-of-field AE with a Manually-Selected Foc\
using
Point” while using the center focusing point to set the DEP points.
• Be sure to complete each step within 6 seconds (before the viewfinder d\
isplay
turns off) after removing your finger from the shutter button. Otherwis\
e, the DEP
settings will be canceled and you will have to start over.
Depth-of-field AE with Eye-Selected Focusing Points
With Eye Control, you can set the DEP points by looking at the focusing
point. This is the easiest way.
