1. Turn the exposure mode setting dial to “ Av ”
(aperture priority AE) position.
Aperture Priority AE (Av)
Set the desired aperture, and the camera selects the optimum shutter speed
accordingly. Use the Av mode to maintain specific control over depth of field, i.e.
taking portraits or landscapes.
2. Turn the front or rear dial to set the desired
aperture.
The shutter speed value will blink when the subject is too dark or too bright for a
correct exposure. To obtain the correct aperture, adjust the aperture value until the
shutter speed value stops blinking and remains lit.
Exposure Modes (continued)
1. Increment of the aperture can be set to your preference.
Custom settings (C-01 on page 84)
2. Rotation direction of the dials to change the values can be altered.
