FP FLASH
(Except SA-300)
When you take a picture with an ordinary flash, you cannot use a shutter speed faster than the
camera’s synchronized speed because the flash must fire when the shutter curtain is fully open. The
FP flash keeps firing, while the shutter curtain is running. Thus you can use a shutter speed faster than
the synchronized speed.
1. Set the camera’s exposure mode to M mode.
2. Press the MODE button on the flash unit, to select the M.
3. Press the + or – button and make the indicate
indicator appear on the LCD panel.
4. Set the shutter speed.
5. Read-out the subject distance from the focus ring on the lens.
Then, adjust the aperture value until the distance indicated on the LCD panel of the flash matches
the subject distance on the lens as closely as possible.
6. When the Ready Light of the flash is illuminated, the unit is ready for use.
■ Depending on the shutter speed, the Guide Number will be changed.(Please refer to table2 on the
last page)
■ When you use the FP flash, do not use the Wide Panel.
■ You cannot set the Second Curtain Synchronization while the flash unit is set on FP Flash
■ If you want to cancel the FP Flash mode, please follow the FP flash procedure to make the
indicator display from the LCD panel.
SECOND CURTAIN SYNCHRONIZATION
When you photograph a moving subject with slow synchronization, usually the furrow of the subject
will be exposed in front of the subject. The ordinary flash light will fire when the first shutter curtain is
fully opened, thus the subject will be exposed from the time flash is fired to the time the shutter is
closed (This is called First Curtain Synchronization). When you use second curtain synchronization,
the flash will fire just before the second curtain begins to close and and the subject will be exposed by
ambient light from the time the shutter opens until the flash fires. The furrow of the subject will
therefore be exposed behind the subject. This is a more natural effect.
1. Set the desired picture-taking mode of the camera.
2. Select the Mode of the flash. (TTL, M modes. SD9, SD10 SD14
and SD15 can be used in M mode only)
3. Press + or – button mark will be displayed on the LCD
panel.
4. Adjust the focus and take the picture after confirming the ready
light is lit.
■ First curtain synchronization will be set if
mark is not displayed.
■ In the Full Auto Mode “ ” of SA-300, SA-300N, SA-5 cameras, this function cannot be used.
■ To cancel second curtain synchronization, turn off the mark on the LCD panel.
RED-EYE REDUCTION
When you take a picture with flash, sometimes the person’s eyes reflect the flashlight and will exhibit
“red-eye” in the picture. If you use the function of “Red-eye reduction”, the flash will blink
approximately 1 second before the shutter is released, and reduce the “red-eye”.
1. Press the MODE Select the mode of the flash(TTL, M modes)
2. Press + or – , button and make mark displayed on the
LCD panel.
3. Adjust the focus, and take the picture after confirming the ready
light is lit.
■ To cancel the “Red-eye reduction” turn of the mark.
■ In the Full Auto Mode “ ” of SA-300, SA-300N, SA-5 cameras,
this function cannot be used.
