Read out the subject distance from the focus ring on the lens. Then adjust the aperture ring on the lens

until the distance indicated on the LCD panel of the flash and the subject distance become about equal.

When using with cameras other than the above

Read-out the subject distance from the focus ring on the lens. Either change the flash power level or

the flash’s F-stop. Please refer following on how to change the flash’s F-stop.

1. Press the SEL button several times to make the F-stop indicator blink.

2. Press the + or – button and set the F-stop.

3. Press the SEL button and make the indicator of F-stop stop blinking.

Please set the distance indicated on the LCD panel of the flash and the actual subject distance so that they

are about equal.

Then set that F-stop on the lens aperture ring.

* You can calculate the correct exposure by using this formula:

Guide Number “GN” / Flash to Subject Distance = F-stop

This flash unit will calculate and indicate the Subject Distance by following the above formula.

(Please refer to table 1 on the last page)

BOUNCE FLASH

When you take a photo with flash in a room, sometimes a strong shadow will appear behind the

subject If you point the flash head upwards or sideways to reflect the light off the ceiling, wall etc, the

subject will be illuminated softly. Press the lock button and adjust the flash head to set the bounce

angle.

UP: 0°, 60°, 75°, 90° DOWN: 0°,7°

RIGHT: 0°, 60°, 75°, 90

°

LEFT: 0°, 60°, 75°,90°, 120°, 150°, 180°

When the bounce flash mode is activated, a bounce indicator

will appear on the LCD panel.

Choose a white surface for bouncing the flash, otherwise the

image’s colour may be incorrect. Depending on the reflecting

surface, the subject distance and other factors, the effective

distance range for the TTL AUTO may change. Please check for

correct exposure confirmation (TTL BL or TTL mark on the LCD

panel) after releasing the shutter.

CLOSE-UP EXPOSURES

Bounce flash can be tilted 7° downward for close-ups. The Flash will be effective only for the subjects

0.5 meter to 2 meters. When the flash head is tilted 7°

will blink.

CATCH LIGHT PANEL

This flash is equipped with a built-in catch

light panel, which can create a catch light in

the eyes of the subject when the bounce

flash mode is activated. Slide out the wide

panel and catch light panel, and then put

wide panel back in its place. (Be careful to

slide the panels out smoothly.)

◆ To create a catch light effectively, tilt the flash head upward 90 degrees and take pictures at a close

distance.
