To determine how the
camera sets shutter speed
and aperture when
adjusting exposure, press
the I (Q) button and
rotate the main command
dial until the desired option
appears in the top control
panel.
A Lens Types
When using a CPU lens equipped with an aperture ring (0 387), lock
the aperture ring at the minimum aperture (highest f-number).
Type G
lenses are not equipped with an aperture ring.
Non-CPU lenses can only be used in exposure mode g (aperture-priority
auto) and h (manual).
In other modes, exposure mode g is
automatically selected when a non-CPU lens is attached (0 388).
The
exposure mode indicator (e or f) will flash in the top control panel and
g will be displayed in the viewfinder.

To preview the effects of aperture, press and
hold the Pv button.
The lens will be stopped
down to the aperture value selected by the
camera (modes e and f ) or the value chosen by
the user (modes g and h), allowing depth of field
to be previewed in the viewfinder.

This setting controls whether optional flash units such as the SB-910,
SB-900, SB-800, SB-700, and SB-600 (0 194) will emit a modeling flash
when the Pv button is pressed.
