Programmed Auto Exposure Modes (PH, 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 fl4 P. For lenses without a CPU, exposure mode is automatically set to Aperture-Priority Auto (A). Setting the exposure mode to PH (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'snormal and high-speed programs. Follow either colored line to where it intersects a diagonal line. This shows the combination of aperture (vertical line) and shutter speed (horizontal line).
