F: Aperture-Priority Ae - Canon GP series Owner's Manual

f: Aperture-Priority AE

In this mode, you set the desired aperture and the camera sets the shutter
speed automatically to obtain the standard exposure suiting the subject
brightness. This is called aperture-priority AE. A higher f/number (smaller
aperture hole) will make more of the foreground and background fall within
acceptable focus. On the other hand, a lower f/number (larger aperture hole)
will make less of the foreground and background fall within acceptable focus.
* <f> stands for Aperture value (aperture opening).
Blurred background
(With a low aperture f/number: f/5.6)
