In aperture-priority auto, you choose the aperture while the camera automatically 
selects the shutter speed that will produce the optimal exposure. Large apertures 
(low f-numbers) reduce depth of field, blurring objects behind and in front of the 
main subject. Small apertures (high f-numbers) increase depth of field, bringing out 
details in the background and foreground. Short field depths are generally used in 
portraits to blur background details, long field depths in landscape photographs to 
bring the foreground and background into focus.

To take photographs in aperture-priority auto:

While the exposure meters are on, rotate the 
sub-command dial to choose the desired 
aperture from values between the minimum 
and maximum for the lens.

Use the lens aperture ring to adjust aperture. If the maximum 
aperture of the lens has been specified using the Non-CPU lens 
data item in setup menu (

0 159) when a non-CPU lens is attached, 

the current f-number will be displayed in the viewfinder and 
control panel, rounded to the nearest full stop. Otherwise the 
aperture displays will show only the number of stops (

F, with 

maximum aperture displayed as

read from the lens aperture ring.
