1 . Set the exposure mode of the camera. to full auto program ( However, depending on the camera exposure setting may vary ). Please refer to Camera’s Instruction manual.
2. Slide the flash mode to i-TTL or TTL BL
3. Focus onto the subject.
4. Press the shutter button after the flash is charged, the Auto check ( ok ) will light up. If Auto check ( ok ) no light up, the flash power is not sufficient for that situation. Please retake the picture at a distance closer to the subject.
▆ If you use the AF camera with AF lens, the AF illuminator will turn on automatically as you focus on a subject in a dark area. However the AF illuminator will not light up if central focus area is not selected. Note: Effective distance is up to about 0.7 to 6 meter .
▆
When the flash is fully charged, the flash mark will appear in the finder. If the shutter is released before the flash is fully charged, the camera will take the picture at a slow shutter speed, with no flash.
This flash unit can be used in 4 steps of manual power , ie FULL, 1/2 , 1/4 , and 1/8.
1. Slide the Flash mode selector to FULL, 1/2, 1/4,or 1/8.
2. Focus on the subject and set the camera’s F-stop, using the exposure calculated by the formula shown below:
F-stop = Guide Number ( G.N.) ÷ Flash to Subject Distance ( m )
3. After the flash is fully charged , press he Shutter Release button to take the picture.
Guide Number will change according to the Zoom Head position, ( see «Table 1» ). Guide
Number will also change according to film speed ( ISO ),(see «Table 3 » ). In the case of non-
ISO 100 speed films, multiply the « Table 3 » number by the « Table 2 » number. For example, using ISO400 film, Zoom Head position for 50mm and the FULL mode ; multiply the « Table 3 » number “2”by the « Table 1» number “38” : 38x 2 = 72. This will be the new effective Guide
Number ( G.N.) in meters. To determine the G.N. in feet, multiply the G.N. in meters by 3.3.
EX . IF flash to subject distance is 10 meters:
F-stop = 76 ÷ 10 = 7.6 ( 8 is the F-stop to set on the camera. )
•The flash unit car adjusts the zoom head position from 24 mm to 85mm. to provide angle of coverage which matches the focal length of the lens in use .
•By pushing the zoom setting Knob ( 2 ) and will show in zoom position widow ( 4 ).
•The guide number changes when the flash coverage angle is changed.
