PREVIEWING THE DEPTH OF FIELD
Before taking a picture, you can check the depth of field in the viewfinder.

ABOUT FOCUSING
EFFECT OF APERTURE AND SHUTTER SPEED
A correct exposure is established by a combination of shutter speed and aperture setting according to the subject bright- ness. There are many correct combinations of shutter speed and aperture for a particular subject brightness. Different shutter speed and aperture settings produce different effects.

qWhile looking through the viewfind- er, press the preview button.
You can check the focused area in the viewfinder.
Memo
•The depth of field can be previewed in any exposure mode.
•The focus range display in the viewfind- er may differ slightly from the actual picture.
◆Effect of Shutter Speed
The shutter speed determines the film exposure time, or the length of time that light is allowed to strike the film. If the subject is moving, the image will be blurred when a slow shutter speed is used. It is possible to enhance the effect of motion, (The movement of a wave or waterfall) by intentionally using a slower speed. Choosing a faster shutter speed will allow the image of a moving subject to be frozen. A faster shutter speed also helps prevent camera shake.
◆Effect of Aperture
The aperture increases or reduces the amount of reflected light from an object which passes through the lens, controlling how much light strikes the film. If the aper- ture is opened up to increase the amount of light, objects in front of and behind an in- focus subject will not be focused. That is, the range of focus (depth of field) becomes small. If the aperture is closed down to reduce the amount of light, the depth of field increases. For instance, if you shoot a person against a landscape with the aper- ture open, the landscape in front of and behind the person will be blurred, making the person appear to rise out of the land- scape. By contrast, closing down the aper- ture increases the
