Nikon D80 Benutzerhandbuch

When using a CPU lens equipped with an aperture ring (

 117), lock the aperture ring at the minimum aper-

ture (highest f/-number).  Type G lenses are not equipped with an aperture ring.

Non-CPU lenses can only be used in exposure mode M, when aperture can be adjusted manually using 
the lens aperture ring (in other modes, the shutter-release will be disabled). The camera exposure me-
ter, ISO Auto, and variety of other features can not be used (

 117).

Use Custom Setting 7 (ISO auto; 

 88) to enable auto ISO sensitivity control in P, S, A, and M modes.  

Custom Setting 10 (EV step; 

 89) determines the size of the increments used for exposure control.  

Custom Setting 15 (Command Dials; 

 91) determines the roles played by the main and sub-com-

mand dials in setting shutter speed and aperture.

P, S, A, and M modes off er control over a variety of advanced settings, including exposure (   
52), white balance, and image optimization.  Each of these modes off ers a diff erent degree 
of control over shutter speed and aperture: 

Programmed auto 
(

 47)

Camera sets shutter speed and aperture for optimal exposure.  Recom-
mended for snapshots and in other situations in which there is little 
time to adjust camera settings.

Shutter-priority auto 
(

 48)

User chooses shutter speed; camera selects aperture for best results.  
Use to freeze or blur motion.

Aperture-priority auto 
(

 49)

User chooses aperture; camera selects shutter speed for best results.  
Use to blur background or bring both foreground and background into 
focus.

M Manual (

 50)

User controls both shutter speed and aperture.  Set shutter speed to 
“bulb” or “--” for long time-exposures.
