FP High-Speed Flash sync

% in Manual Flash ƒ mode

For F5, F100, F90X/N90s, F90-Series/N90

The SB-28 allows you to use faster shutter speeds for flash
synchronization. With FP High-Speed Flash sync

%, the flash emits light

at an extremely rapid rate, while the shutter curtains travel to expose the
film. This enables you to use a faster shutter speed as well as a wider
aperture to achieve shallower depth of field to blur the background.

• Attach the SB-28 to the camera and turn on both the SB-28 and the camera, then

set the SB-28 to FP High-Speed Flash sync

Set the exposure mode to Manual (M).

Set the aperture.

—With Nikkor lenses with a built-in CPU: Rotate the command dial on the

camera or the lens aperture ring (for F90X/N90s, F90-Series/N90
cameras) as you watch the indicator bar

¡ on the LCD panel change to

match the shooting distance.

—With Nikkor lenses without a built-in CPU: Press the

{ or } button to

change the aperture on the LCD panel. Then set the same aperture on
the lens aperture ring.

Set the shutter speed.

—Set the shutter speed between 1/250 and 1/4000 sec.
• The guide number for FP High-Speed Flash sync

% varies with the

selected shutter speed and is less than that for regular flash
synchronization. (See page 51 on

% guide numbers.)

• In the

% mode, when taking flash photographs with a shutter speed

slower than 1/250 sec., it is recommended to use normal flash operation
because the guide number is less in the

% mode.

• If you set the SB-28’s flash mode to a mode other than Manual

ƒ %

with your camera’s shutter speed set higher than 1/250 sec., the shutter
speed is automatically set to 1/250 sec.
