, S, A, and M modes offer different degrees of control over shutter 

speed and aperture.

A

When using a CPU lens equipped with an aperture ring (

0 287), lock the aperture ring at the 

minimum aperture (highest f-number). Type G and E lenses are not equipped with an 
aperture ring.

Non-CPU lenses can only be used in modes A (aperture-priority auto) and M (manual), when 
aperture can only be adjusted using the lens aperture ring. Selecting any other mode 
disables the shutter release.

A

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 (

0 172) 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 

FA) and the f-number must be 

read from the lens aperture ring.
