• For details on the manual flash, see page 32. GB26 Test-flash Test-flash Press the TEST button when the TEST button lights up in amber. • The light level of the test-flash depends on the light level which set in the LEVEL setup. TEST button The TEST button is turned on as follows according to the current state of the flash unit. • Amber: Flash ready • Green: Proper exposure • Red: Overheating* * Overheating is a function which flash suspends operation automatically, when the temperature of this unit rises at the time of continuous flash use or use in a high temperature environment. • The TEST button blinks in red at intervals of 1 second when overheating is detected. • The flash operation is suspended until the temperature of the unit falls. • Stop use of the flash unit for 10 minutes to allow the temperature of the unit to cool down. Appl ications 27GB Bounce flash Bounce flash Bounce flash Normal flash Rotate the flash unit upwards or to the left and right while pressing the bounce lock-release button. GB28 • Upwards: 45°, 60°, 75°, 90° • Right: 30°, 45°, 60°, 75°, 90°, 120°, 150°, 180° • Left: 30°, 45°, 60°, 75°, 90° • The bounce lock engages at the 0° position. When the flash unit is returned to the original position, the lock-release button needs not to be pressed. • When the flash is rotated upwards or to the left and right, the High-speed sync (page 34) is also cancelled. • Use a white ceiling or wall to reflect the flash. A colored surface may color the light. High ceilings or glass are not recommended. Applications 29GB Adjusting bounce angle Adjusting bounce angle Correct Incorrect When the flash is bounced upwards Determine the angle in relation to the following table. Focal length of lens Bounce angle 70 mm minimum 45° 28 - 70 mm 60° 28 mm maximum 75°, 90° Bouncing to Left and Right Rotating the flash by 90° to bounce light sideways is recommended. If an angle of less than 90° is used, care should be taken to ensure that direct light from the flash unit does not illuminate the subject. GB30 AF illuminator AF illuminator • The AF illuminator operates even when the Flash-OFF lamp [ ] is lit. • The camera AF illuminator does not operate while the flash AF illuminator is operating. • The AF illuminator does not operate while Continuous AF is used in focusing mode (when continually focusing on a moving subject). • The AF illuminator may not operate if the focal length of the lens is greater than 300 mm. The flash unit will not operate when removed from the camera. Applications 31GB Manual flash (M) Manual flash (M) • Manual flash can only be used when the camera is in the M mode. In other modes, TTL measuring is automatically selected. • As manual flash is not affected by the reflectivity of the subject, it is convenient for use with subjects with extremely high or low reflectivity. TTL flash metering Manual flash metering 1 Select the M mode on the camera. 2 Press the MODE button to display the Flash-ON lamp [ ] on the display panel. GB32 3 3 • The power level is changed in following order. 1/1 t 1/2 t 1/4 t 1/8 t 1/16 t 1/32 t 1/1 t . . . • For details on setting the power level, refer to page 49. • The flash range check indication of the TEST button (blinks in green) does not work after a photo is taken with the manual flash. • Using custom functions, manual flash may be selected without setting the camera in the M mode (page 44). TTL flash Manual flash provides a fixed flash intensity irrespective of the brightness of the subject and the camera setting. TTL* flash measures the light from the subject that is reflected through the lens. Some cameras enable P-TTL metering, which adds pre-flash to TTL metering, and ADI metering, which adds distance data to the P-TTL metering. This flash unit defines all P-TTL and ADI metering as TTL flash and the LEVEL lamp [AUTO] on the display panel lights up. *TTL = through the lens • ADI metering is possible in combination with a lens with a built-in distance encoder. Before using the ADI metering function, check whether your lens has a built-in distance encoder by referring to the specifications in the operating instructions supplied with your lens. Appl ications 33GB High-speed sync (HSS) High-speed sync (HSS) High-speed sync Normal flash High-speed sync eliminates the restrictions of flash sync speed and enables the flash to be used through the entire shutter speed range of the camera. The increased selectable aperture range allows flash photography with a wide aperture, leaving the background out of focus and accentuating the front subject. Even when photographing at a wide f-stop in the A mode or M mode of the camera, when the background is very bright and the shot will normally be over-exposed, you can adjust the exposure by using the high-speed shutter. Press the HSS button. • The high-speed-sync lamp lights up. GB34 • • • If you press HSS button again, high-speed sync is cancelled. When high-speed sync is cancelled, the shutter speed cannot be set faste...
