The power level range (e.g. 1/1 t1/2) corresponds to the aperture range (e.g. F4 t5.6). Applications 45 Multiple flash (MULTI) The flash is triggered a number of times while the shutter is open (multiple flash). Multiple flash allows motion of the subject to be captured in a photograph for later analysis. • The camera must be set to the M mode for multiple flash photography. Multiple flash can only be used if the camera supports the M mode. 1 Set the camera to the M mode. 2 Press the mode button to display of the data panel. 3 Press the select button to blink “Hz.” • The current multiple flash frequency (flashes per second) is displayed on the data panel. 4 Press the + or – button to select the flash frequency. • The flash frequency may be selected from the following. 100, 50, 40, 30, 20, 10, 9, 8, 7, 6, 5, 4, 3, 2, 1 • Keep the + or – button pressed down to repeatedly change the value. Applications Continued on the next page 47 5 Press the select button to blink “TIMES.” • The current number of flashes for multiple flash is displayed on the data panel. 6 Press the + or – button to select the number of flashes. • The number of flashes may be selected from the following. - -, 40, 35, 30, 25, 20, 15, 10, 9, 8, 7, 6, 5, 4, 3, 2 • Keep the + or – button pressed down to repeatedly change the value. • When “--” is selected, flashes continue at the set frequency while the shutter is open. 7 Press the select button to blink “LEVEL” on the data panel. • The current power level is displayed. 8 Press the + or – button to select the power level to set. • The power level may be selected from the following. 1/8, 1/16, 1/32 9 Press the select button. 10Set the shutter speed and aperture. • The shutter speed is calculated as follows to suit the selected flash frequency and number of flashes. Number of flashes (TIME) . Flash frequency (Hz) . Shutter speed For example, when ten flashes and 5 Hz are selected, 10 . 5 = 2 requires a shutter speed of longer than two seconds. 11 When the flash is fully charged, press the shutter button to take the photo. • The distance at which the proper exposure is obtained with a single flash is displayed on the data panel. • To prevent shaking, the use of a tripod is recommended during multiple flash photography. • Test flash will flash at the selected frequency/number/level while the test-flash button is being pressed if the selection switch is at or HOLD. • The use of custom settings allows the camera to be set up for manual flash photography without selecting the M mode (p. 54). Applications Continued on the next page 49 Maximum number of continuous flashes The maximum number of continuous flashes during multiple flash photography is limited by the charge in the battery. Use the following values as a guide.

If the external battery adaptor FA-EB1AM (optional) is used, the maximum number of flashes increases beyond the values given above. Reset to default settings Press the + and - buttons together for three seconds. Most flash functions return to default settings.
