User manual METZ MECABLITZ 54 MZ-4I

[. . . ] En jouant sur l'ouverture du diaphragme ou sur le niveau de puissance, la distance affichée pourra être ramenée à la valeur de la distance réelle de prise de vue. Lorsque le mecablitz est utilisé avec un adaptateur SCA 3xx2 sur un appareil photo qui transmet automatiquement la distance focale de l'objectif au mecablitz, la position de la tête zoom motorisée du mecablitz est asservie automatiquement à la distance focale de l'objectif. Il se peut que l'adaptation automatique à la distance focale (AUTO-ZOOM; CZ) soit désactivée sur le mecablitz et que l'on ait choisi sur le réflecteur une distance focale qui est supérieure à celle de l'objectif. Exemple : distance focale de l'objectif 70 mm, distance focale du réflecteur 85 mm. [. . . ] A test flash cannot be fired in TTL mode. The test flash can be triggered with the manual firing button (Fig. 1) provided that this button has not been programmed for , , Modelling Light" (see Chapter 12. 1) remains dark after the test flash was fired, then adjust the next lower f-number, or diminish the distance to the reflecting surface or subject, and repeat the test flash. The f-stop established in this manner must also be set on the camera.  To trigger a test flash , hold the camera and flash unit in the same manner as for the actual shot!This facility can also be used with TTL mode without having to produce test exposures. The flash unit is adjusted to automatic mode, and the correct aperture is then determined with a test flash in the previously described manner. 2) can only be activated by autofocus cameras that support the AF measuring beam of the flash unit!Some autofocus cameras only support their own built-in AF illuminator (refer to the operating instructions for the given camera). The mecablitz must be fitted with an SCA 3xx2 adapter! Please note when selecting the camera's autofocus mode that most cameras only support the AF measuring beam in the , , Single AF" or , , One-Shot AF" mode (see operating instructions for the camera)!The AF measuring beam is activated by the camera electronics when the ambient lighting conditions are insufficient for automatic focusing. The AF beam projects a striped pattern on to the subject, and the camera uses this pattern to focus automatically.  Some autofocus cameras have several AF metering fields in addition to the central AF metering area in the camera's viewfinder. the striped pattern of the AF measuring beam only supports the camera's central AF sensor. Consequently it may be necessary to adjust the central AF sensor manually on the camera (see the operating instructions for the given camera and the SCA adapter). The special functions of the mecablitz can be called, one after the other, by depressing the Select button (Fig. 1), and they can be set, switched off and stored with the setting disk (Fig. It enables the photographer to concentrate fully on the subject without being distracted by the need to observe additional visual status displays!) uninterrupted bleep signal immediately after shooting indicates that exposure was correct and that flash readiness continues. If there is no bleep signal immediately after shooting the picture was underexposed. [. . . ] Automatic focal length adaptation (AUTO-ZOOM, CZ) may have been deactivated on the mecablitz, and a reflector focal length has been selected that is longer than the focal length of the lens. Remedy: Activate automatic focal length adaptation on the mecablitz (AUTO-ZOOM or CZ) or ensure that the reflector focal length is identical with, or shorter than, the focal length of the lens. (Pe) The power zoom reflector of the mecablitz automatically assumes the 35 mm position, even though a lens with a different focal length is being used. A non-AF lens, or a lens that does not transmit focal length data to the camera, is being used. [. . . ]
