Set the aperture value for controlling the depth of field. The depth of field
is deeper and the front and back of the focused object is clear when the
aperture is set to a large value, small lens opening. The depth of field is
shallower and the front and back of the focused object is blurred when the
aperture is set to a small value, large lens opening.
The shutter speed is automatically set to the proper exposure depending
on the aperture value.

Exposure Warning
If the subject is too bright or too dark,
the aperture value will blink on the
status screen and LCD panel and in
the viewfinder. If the subject is too bright, choose a faster shutter
speed. If it is too dark, choose a slower shutter speed. When the
aperture value indication stops blinking, you can take a picture with
proper exposure.
Use a commercially available ND (Neutral Density) Filter if the subject
is too bright. Use a flash if it is too dark.
