[. . . ] Si le flash est utilisé avec un appareil photo qui transmet au flash la valeur de la distance focale de l'objectif, la tête zoom motorisée s'adapte automatiquement à cette distance focale. 1 Manual flash mode M with full light output . 2 Manual flash mode MLo with partial light output levels. 65 Guide number table for TTL and full light output M in the imperial system . [. . . ] Accordingly, shutter speeds that are slower than the flash's sync speed are automatically adjusted by the camera. Some cameras automatically activate SLOW synchronisation in connection with certain camera programs (e. No settings are made on the flash unit nor is there any display for this mode. In normal synchronisation the flash unit is triggered at the beginning of the shutter time (1st curtain synchronisation). normal synchronisation is the standard mode on all cameras , and is suitable for most flash shots. Depending upon the given mode, the camera is changed over to the camera's sync speed, the customary ones being between 1/30th sec. No settings have to be made on the flash unit, nor is there any display for this mode. The flash readiness symbol lights up on the flash unit when the flash capacitor is charged, thereby indicating that flashes can be fired for the next shot. If a picture is shot before flash readiness is signalled in the camera's viewfinder, then the flash unit will not be triggered so that the exposure may be incorrect if the camera has changed over to flash sync speed in the meantime (see 5. Symbols in viewfinder: Meaning: Flash readiness indication: Flash symbol lights constantly or flashes slowly: The flash unit is ready for firing. A flash is fired when the camera's shutter release is pressed. Correct exposure confirmation: Symbol flashes rapidly after shooting: The picture was correctly exposed. Symbol flashes: The existing shooting situation requires the use of flash. Depending upon the camera model and camera mode, the shutter speed is changed to flash sync speed when flash readiness is reached (see camera's operating instructions). Shutter speeds faster than the camera sync speed cannot be adjusted or they are automatically changed to the camera's sync speed. The actual sync speed set by the camera depends upon the camera mode, the ambient light and the focal length of the lens used.  The symbols indicated in your camera's viewfinder may deviate from Those given in the above table, since some symbols are only possible on specific cameras. For more details regarding viewfinder information please refer to the operating instructions of your camera. Shutter speeds slower than the flash sync speed can be set, depending upon the given camera model and the selected flash synchronisation (see also 4. There is no automatic flash sync speed control with the digital cameras Dimage 5, 7 and 7i. These cameras permit flash shots to be taken at all shutter speeds. Should not be used for shooting situations where full light output of the flash unit is required. [. . . ] Remove any grime and dust with a soft, dry or silicon-treated cloth. Never use detergents that could damage plastic parts. The flash capacitor incorporated in the flash unit undergoes a physical change when the flash unit is not switched on for prolonged periods of time. For this reason it is necessary to switch on the flash unit for approx. [. . . ]
