User manual METZ MECABLITZ 34 AF-3 C FOR CANON

[. . . ] 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. The high energy of the flash light will burn the material or damage the screen if this is not observed!There are no components inside the flashgun that can be repaired by a layperson. [. . . ] The sync speed depends on the camera model and usually ranges between 1/30 sec. Some camera models will, when the flash unit is on, switch it to flash sync speed as soon as program mode , , P" or full-auto mode is selected. 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. camera-specific deviations ar possible (please refer to the camera's operating instructions. Blinks: Indicates that flashgun should be used or switched on (on some cameras). The flash is ready for use (on some cameras) Please refer to your camera's operating instructions to find out if this applies to your camera model. 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!E-TTL flash control is only possible with cameras featuring this function. In the E-TTL flash control mode, a pre-flash is fired to establish the reflective characteristics of the subject just before the actual shot is taken. A partial light output level is transmitted and adjusted on the flash unit as a result of this measurement. [. . . ] The camera's computer-controlled measuring system automatically selects the shutter speed, working aperture and light output in such a manner that both the main subject in the foreground as well as the background are uniformly exposed. 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.
