Aperture > Priority AE Mode
Purpose:
Allows the user to directly control the lens aperture.
This mode is ideal for shooting landscapes with
increased depth of field, or a portrait against a
blurred background. When the desired aperture is
selected, an appropriate shutter speed is automati¬
cally set by the camera for a proper exposure.
1. Set the lens aperture ring to the desired f-
stop other than [ A ].
