Programmed Auto exposure mode
(¡)
With the F5’s microcomputer choosing
the combination of shutter speed and
aperture automatically, you can concen-
trate on picture composition without
worrying about exposure.
Note that programmed auto exposure
modes operate only with Nikon lenses
that have a built-in CPU (AF Nikkor and
AI-P Nikkor lenses).
Programmed Auto exposure mode is
used for most common picture-taking
situations.
In Programmed Auto exposure mode,
you can use the Flexible Program function
to temporarily shift an automatically
selected shutter speed/aperture combi-
nation and obtain the desired shutter
speed/aperture while retaining the same
or a consistent exposure (see pages 68
and 69).
Program chart
To check shutter speed and aperture values, follow the red line to where it intersects
the diagonal line. This shows the combination of aperture (vertical line) and shutter
speed (horizontal line).
