Congratulations on purchasing our flash 28 AF-3 digital and thank you for the confidence in our products. The following pages give useful instructions for proper operation of the flash unit and a survey of all its sophisticated functions. Please read these operating instructions carefully, even if one or the other point may not appear to be very insteresting at first sight. [. . . ] When the shutter release is pressed the picture will be exposed with the previously determined light output. Due to system-inherent reasons any changes in the light situation after the FE test flash has been fired will not be taken into account when the picture is shot. Some cameras do not support FE flash exposure storage in the "green" full auto mode or programmed image control modes (see camera's operating instructions). Prior to shooting, the reflection of the subject is measured with a preflash. The camera evaluates the reflected preflash light so that the subsequent flash exposure is optimally adapted to the prevailing photographic situation (see operating instructions of your camera). In this mode the camera additionally takes into account the data relating to the subject's distance (see operating instructions of the camera).  These flash modes are only available with When shooting a picture, several weakly visible preflashes are fired by the flash unit prior to exposure. The camera then evaluates the reflected preflash light so that the subsequent flash exposure is optimally adapted to the prevailing photographic situation (see operating instructions of the camera). I-TTL-BL flash mode With this setting in i-TTL flash mode, the camera additionally takes into account data relating to the subject's distance (see above). In this mode, the reflector status (operation with or without wideangle diffuser or telephoto attachment) must be adjusted correctly. For i-TTL-BL flash mode, both the camera and the lens must support the evaluation of distances (see operating instructions of the camera and the specifications for the given lens). 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. Shutter speeds slower than the flash sync speed can be used, depending upon the camera mode and the selected flash synchronisation (see also 5. " correct exposure confirmation only appears for about 3 s in the flash unit's LC display if the shot was correctly exposed in TTL flash mode or the corresponding advanced variant of TTL flash mode. If "ok" is not displayed then this means that the shot was underexposed. The shot will then have to be repeated with the next smaller f-number (e. Depending on the type of camera used, the flash unit transmits the correct exposure confirmation signal to the camera for corresponding indication in the viewfinder or on the camera's display panel (for system-inherent reasons, this does not apply to Canon and Olympus cameras).  Various digital cameras are equipped with a between-the-lens shutter. Such cameras permit the use of flash at all shutter speeds, however there is no automatic flash sync 95 If you need the full light output of the flash unit you should not set shutter speeds faster than 1/300 sec. Display and match it to the given correction value (depends upon the camera model)!Exposure correction by changing the lens diaphragm is not possible because the camera's automatic exposure system will automatically regard the changed diaphragm as the normal working aperture. [. . . ] Accordingly, no flash is triggered when the camera's shutter release is pressed. On various cameras, the triggering control only works in the Full Auto Mode or Program "P", or it must be activated on the camera (see operating instructions of the camera). The AF measuring beam of the flash units 28 AF-3 C, 28 AF-3 M und 28 AF-3 N can be deactivated if this is required: · Keep the "MODE" key and the manual firing button depressed.  On some cameras, the preflash function only Supports the camera's internal flash unit or an illuminator incorporated in the camera body (see operating instructions of the camera).
