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 %.

Camera settings

1Set the exposure mode to Manual (M).

2 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.

3 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.
