Nikon F4S - Programmed Auto Exposure Modes

l ate
Programmed Auto Exposure Modes (Pu, P)
Programmed auto operation is ideal for quick operation and is
the simplest method for exposure control. Together with Matrix
Metering, it is very reliable.
Programmed Auto Exposure modes can only be used with
lenses having a built-in CPU such as AF-Nikkor lenses and the
Nikkor 500mm f/4 P. For lenses without a CPU, exposure mode
is automatically set to Aperture-Priority Auto (A). Setting the
exposure mode to Px (high-speed program) or P (normal
program) lets you choose normal or high-speed program. For
a higher shutter speed, such as when using a telephoto lens,
or for shooting a fast-moving subject, Ph is recommended.
Dual Program Chart (e.g., 50mm f/1.4, ISO 100)
The EV (Exposure Value) chart demonstrates the difference
between the F4's normal and high-speed programs. Follow
either colored fine to where it intersects a diagonal line. This
shows the combination of aperture (vertical line) and shutter
speed (horizontal! tine).
