Taking Photographs—Exposur
e
A: Aperture-Priority Auto
In mode A, you choose the aperture while the camera controls shutter speed
for optimal exposure. Small apertures (high f/-numbers) increase depth of
fi eld, bringing both the main subject and back ground into focus. Large
apertures (low f/-num bers) soften background details and let more light into
the camera, increasing the range of the fl ash and making photographs less
susceptible to blurring. Mode A is only available with CPU lenses.
To take pho to graphs in aperture-pri or i ty auto:
1 Rotate the mode dial to A.
2 Rotate the sub-com mand dial to choose the
de sired aperture.
3 Frame a photograph, focus, and shoot.
If the fl ash-ready indicator ( ) blinks in the viewfi nder, the fl ash can be used for ad-
ditional lighting. The fl ash-ready indicator will not be displayed if Off is selected for
Custom Setting 20 (Flash sign).
Subject too dark. Choose larger aperture (smaller f/-number) or higher
sensitivity (
