A
DVANCED RECORDING
Aperture priority is set with the
exposure-mode dial (p. 50).
The photographer selects the
aperture and the camera sets
the appropriate shutter speed
to ensure the correct
exposure. When A mode is
selected, the aperture display
on the monitors turns blue.
APERTURE PRIORITY - A
Turn either the front or rear control dial to change the aperture. Press the shutter-release
button partway down to activate the exposure system; the corresponding shutter speed
is displayed.
The aperture values can be changed by 0.3Ev or 1/3 stop increments between f/2.8 and
f/11 at the lens’ wide-angle position and f/3.5 to f/11 at the lens’ telephoto position. If the
aperture value is beyond the shutter-speed range, the shutter-speed display will blink on
the data panel and turn red on the monitors.
With the camera sensitivity (ISO) set to auto (p. 74), the shutter speed may not change
when the aperture is adjusted because the shutter speeds can be adjusted in fine steps.
When photographing scenes with very bright objects such as the sun at large apertures (f/2.8 or
f/3.5), streaking may be apparent in the image. Black areas caused by a loss of data may result.
In these situations, stop down the aperture or use neutral density filters to minimize the effect.
Do not point the camera toward the sun for prolonged periods of time. The intensity of the sun
could damage the CCD. Between exposures, turn off the camera or cover the lens.
