[. . . ] La distance d'éclairage minimale est d'environ 10 % de la distance maximale · Si la distance au sujet est inférieure à la portée affichée, vous pouvez choisir un niveau de puissance partielle pour adapter la portée de l'éclair à la distance flash-sujet. Congratulations on purchasing this METZ flashgun, and thank you for your confidence in METZ equipment. It is only natural that you should want to use your flashgun straight away. However, it will be well worth your while to study these Operating Instructions carefully beforehand to ensure that you can operate the flashgun effectively and without any problems. [. . . ] The flashgun must be fitted with a corresponding SCA adapter for this purpose. Exposure corrections may be necessary with pronounced differences in Contrast, for instance dark objects in snow (see Ch. The maximum flash range for the given camera aperture can be read off the setting dial on the reflector opposite the camera's f-number. To check the range, the flash can only be fired by the camera and not by way of the manual firing button on the flashgun (where possible the camera should be adjustet to multiple exposure. A continuous audible sound is generated after a flash has been fired and both the exposure o. 3) and flash ready indicator light up - correct exposure and flash readiness. A continuous audible sound is generated after a flash has been fired and only the exposure o. There is no audible sound after a flash has been fired, and the exposure o. (only with SCA adapter) Perfect flash exposures can be shot in a simple manner in TTL mode. The exposure readings in TTL mode are made by the sensor built into the camera (fig. This sensor measures the light reaching the film through the camera lens. As soon as the film has been exposed by the correct amount of light, an electronic control circuit within the camera transmits a stop signal to the adapter (optional accessory), and the flash is instantly cut out. The advantage of this flash mode is that all factors influencing the exposure of the film (filters, change of aperture and focal length with zoom lenses, In the automatic flash mode the photosensor measures the light reflected from the subject. The flash is cut off as soon as sufficient light has been emitted for correct exposure. In this manner there is no need to calculate and set a new aperture when the distance is changed, provided that the subject remains within the indicated automatic flash range. The photosensor of the flashgun must be directed at the subject, regardless of the direction at which the main reflector is pointing. 25°, and it only measures the actual amount of light emitted by the flashgun. A flash-to-subject distance of 5 m allows for the auto working apertures of f/11 - f/8 - f/5. For group shots where there can be several rows of people behind each other, we recommend an aperture of f/11. The subject should be within the middle third of the distance range. This gives the electronic control sufficient scope for compensation should this be necessary. There is a certain measure of overlap between the individual automatic apertures. [. . . ] Please observe the corresponding explanations in the Operating Instructions for the camera. Here, exposure correction by changing the aperture on the lens is not possible. This is because the camera's automatic exposure system will regard the changed f­stop as a normal working aperture. The wide-angle diffuser widens the horizontal lighting angle from 62° to 65°, and the vertical lighting angle from 42° to 60°. [. . . ]
