User manual METZ MECABLITZ 34 AF-3 N FOR NIKON

[. . . ] Flash fired directly in front of the eyes of a person or animal can damage the retina and lead to severe visual disorders - even blindness!Batteries should not be exposed to excessive heat, for instance sunshine, fire and the like!In the event of flash shots with full light output observe an interval of at least 3 minutes after a series of 20 flashes. â· NEVER place material that is impervious to light in front of, or directly on, the reflector screen. [. . . ] 2 Automatic flash sync speed control Most system cameras automatically change to flash sync speed when flash readiness is reached. The flash sync shutter speeds may vary between 1/30th and 1/300th second, depending on the camera model. 4) The red correct exposure light briefly illuminates when flash exposure was correct. 4 Information displayed in the camera's viewer The following table only gives a general survey. The mecablitz receives its information exclusively from the connected TTL-controlled camera. exposure measurement in TTL mode (TTL = through-the-lens) is completed by the camera's sensor. This sensor measures the light reaching the film through the camera lens. An electronic control circuit within the camera transmits a stop signal to the flashgun as soon as the film has been exposed by the correct amount of light; the flash is then instantly cut out. The advantage of the TTL mode is that all factors influencing the exposure of the film (such as filters, change of aperture or variable aperture zooms) are taken into account. Spot , matrix or centre-weighted overall readings) offered by some cameras.  If the actual distance is shorter than the Minimum lighting distance, then this may result in overexposure. A strip of film must be loaded in the camera if tests are to be conducted in TTL flash mode. The effective flash range can only be checked by the correct-exposure display (o. ) if the flash is triggered by the camera and not with the manual release on the flashgun!Different modes of flash synchronisation are possible, depending on the camera model. Please refer to the camera's operating instructions to find out how the individual modes of synchronisation are set on the camera. With normal synchronisation, switching to the camera's flash sync shutter speed is automatic. The shutter speed may vary from 1/30th and 1/300th seconds, depending on the camera model. Flash shots at low lighting levels and fast shutter speeds (normal flash sync speed) can often result in overexposed subjects in front of a very dark back-ground. The slow-sync function allows the use of slow shutter speeds right up to 30 seconds, to significantly enhance the background as a result of the extra ambient light. [. . . ] A wide-angle diffuser is supplied with the flashgun to increase the coverage if you wish to use a 28 mm wide-angle lens. 7: Mounting and removing the attachments To remove turn the attachment beyond the retaining spring (see fig. Turn the attachment clockwise and insert the guiding edge into the case gap. Forming the flash capacitor The flash capacitor incorporated in the flashgun undergoes a physical change when the flashgun is not switched on for prolonged periods. [. . . ]
