[. . . ] The light control range varies according to the camera setup (ISO speed, lens iris (F) and lens focal length (ZOOM)). Light intensity adjustment The flash light intensity can be adjusted between +3 and ­3. The light intensity adjustment must be set to ON in the custom setup operation (page 61). · The indicator appears in the control panel.

Turn dial B to select a light intensity adjustment value in the following steps. (This selection is also possible with dial A. ) 0 0 +0. 3 ­0. 3 +0. 7 ­0. 7 +1. 0 . . . The display shows the light intensity adjustment value except when the value is 0, in which case the display does not show the light control range. 3. When flash activation has been performed correctly, the AUTO CHECK lamp blinks for about 5 seconds after the shutter is released. Memo: Test flash activation Flash activation can be tested before actually releasing the shutter. The light control is OK when the AUTO CHECK lamp blinks for about 5 seconds after the test flash activation. If the lamp does not blink, change the lens iris (F), ISO speed, subject distance, etc. · The light check by means of test flash activation is possible only in the AUTO mode. 3. If the camera's flash adjustment mode is selected, the actual flash light intensity will be the total of the light intensity adjustment value set on the FL-50 and that set on the camera. The light intensity adjustment value displayed is that of the FL-50 only. Light intensity adjustment value [Example] Selected adjustment value FL-50 Camera +0. 3 +0. 3 Adjustment value Actual light intensity displayed on FL-50 adjustment +0. 3 +0. 6 Light intensity adjustment The flash light intensity can be adjusted between +3 and ­3. <MANUAL> In this mode, the flash is emitted according to the guide number (GN) setting. The light intensity adjustment must be set to ON in the custom setup operation (page 61). · The indicator appears in the control panel. Displayed according to the focal distance of the lens. 1. The control panel shows the current guide number (GN) together with the optimum shooting distance according to the camera setup. 1. Turn dial B to select a light intensity adjustment value in the following steps. (This selection is also possible with dial A. ) 0 0 +0. 3 ­0. 3 +0. 7 ­0. 7 +1. 0 . . . Turn dial A to set the guide number (GN). (This is also possible by turning dial B. ) Set the guide number (GN) so that the optimum shooting distance is equal to the subject distance. When the optimum shooting distance is 0. 6 m (0. 5 m in case of close-up flash) or less, the displayed figure blinks to warn that the subject is located outside the flash light emission area. The optimum shooting distance varies according to the camera setup (ISO speed, lens iris (F), lens focal distance (ZOOM), and shutter speed). Memo: Assuming that the ISO speed is 100, the optimum shooting distance can be calculated with the following formula. [. . . ] In bounce flash photography, the camera's built-in flash can also be used for catch-light photography (see page 59). Subject too close in FP MANUAL mode Change the camera's ISO speed or lens iris (F) setting. Change the guide number (GN) setting. Q Why does the electronic flash get hot after successive firing?A The batteries generate heat when flash firing is repeated successively. In this case, use the electronic flash at intervals until the flash emission section and batteries cool down. 52 Q Why can't I mount the electronic flash on the camera? [. . . ]
