User manual METZ MECABLITZ 34 AF-3 M FOR MINOLTA

[. . . ] Chemicals leaking out of spent batteries will damage the flashgun. Batteries should not be exposed to excessive heat, for instance sunshine, fire and the like!Protect the flashgun against excessive heat and high humidity levels!In the event of flash shots with full light output observe an interval of at least 3 minutes after a series of 20 flashes. [. . . ] 1 Flash-ready indication The green light on the mecablitz illuminates when the flash capacitor is fully primed, thereby indicating flash readiness. This means that flash can be used for the next exposure. the flash readiness signal is transmitted to the camera where it is indicated by a corresponding display in the camera's viewfinder. On some cameras (depending on the model) the shutter is automatically changed to flash sync speed when flash readiness is reached. The flash will not be fired if the shutter is released before the flash ready light illuminates with the result that the exposure may be incorrect if the camera control circuit has already changed over to flash sync speed. 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 viewfinder Camera models 8000i 1)/ 7000i 1)/ 700si 2) 9xi 2)/ 7xi 2)/ 5xi 2) Displays in viewfinder Permanently illuminated Meaning The flashgun will be triggered as soon as the release is pressed. 28 Camera models: blinks blinks slowly blinks rapidly The flashgun is primed and ready for firing The flashgun is primed and ready for firing The light output was sufficient for correct exposure 3xi / 2xi / SPxi / 5000i / 3000i The flashgun is being primed The flashgun is primed and ready for firing The light output was sufficient for correct exposure 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. You need not worry about adjustment of the light output. Spot , matrix or centreweighted overall readings) offered by some cameras. If the actual distance is shorter than the minimum lighting distance, then this may result in overexposure. The speed of films to be exposed under TTL flash control must be between ISO 25/15°* and ISO 1000/31°. Correct exposures cannot be guaranteed with other film speeds. 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! [. . . ] The mecablitz still enables the user to activate the fill-in flash function manually when the camera would shoot the picture without flash (see also page 32 , , Activating the flash manually"). Your mecablitz provides full and even illumination of normal 24 x 36 mm negatives when using lenses of 35 mm focal length and longer. A wide-angle diffuser is supplied with the flashgun to increase the coverage if you wish to use a 28 mm wide-angle lens. Turn the attachment clockwise and insert the guiding edge into the case gap.
