1. Safety instructions • NEVER fire a flash in the immediate vicinity of the eyes! 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! • Spent batteries should be immediately remo- ved. Chemicals leaking out of spent batteries will damage the flashgun. ?[...]

4 2. Preparing the mecablitz for use 2.1 Power supply The flashgun can only be operated with 2 CR2-type lithi- um batteries. This type of battery can be stored for many years with practically no loss of energy, thus making it ideal for occasional amateur flash photography. Batteries have become discharged or spent when recycling takes more than 6[...]

2. Preparing the mecablitz for use 5 When loading the batteries ensure correct pola- rity. Incorrectly loaded batteries can destroy the flashgun! All batteries must be of the same make and have the same charge level. Exhau- sted batteries must not be thrown into the dustbin! Contribute to the protection of the environment and discard exhausted bat[...]

6 3. Setting the mecablitz into operation 3.1 Preconditions The mecablitz must only be used with TTL flash controlled cameras! The sensor of TTL flash controlled cameras measures the light reaching the film through the camera lens and instantly cuts out the flash when the film has been correctly expo- sed. Please refer to the camera’s operat[...]

4. Flashgun instructions to the camera The mecablitz transmits different signals and messages to the camera when it is connected to the camera and is switched on. 4.1 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 [...]

5. TTL flash control The mecablitz receives its information exclusively from the connected TTL-controlled camera. Exposure measurement in TTL mode (TTL = t hrough- t he- l ens) 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 [...]

6. Flash synchronisation Different modes of flash synchronisation are pos- sible, 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. 6.1 Normal synchronisation This mode is available with all TTL cameras, and it is suitable for most ?[...]

6. Flash synchronisation 6.3 Second curtain synchronisation (REAR) Some cameras offer the facility of second shutter curtain synchronisation. With normal synchronisation, the flash is fired pre- cisely after the opening of the first shutter curtain. When using slow shutter speeds, and with moving objects, this would result in an unnatural rendit[...]

7. Flash in the individual camera modes Auto program mode with flash (P-function) In this mode, the camera automatically activates the flash function when the ambient light level is too low, it automatically adjusts the aperture and shutter speed, and triggers the flash when the shutter release is pressed. The flashgun is not triggered in the c[...]

8. Autofocus measuring flash The integrated AF red-light beam of the mecablitz supports the automatic focusing of autofocus TTL cameras. When the prevailing light is insufficient for automatic focusing, the mecablitz will project a pattern of red vertical stripes onto the subject as soon as the camera’s release is lightly touched (or is activate[...]

14 9. Flash techniques and flash functions 9.1 Fill-in flash Normally, the automatic flash function (P-function) will automatically fire the flash in daylight when shooting against the light. However, the camera may well measure sufficient ambient light so that the flash firing circuit is not activated (see page 32). The mecablitz still enab[...]

15 10. Lighting and attachments Your mecablitz provides full and even illumination of normal 24 x 36 mm negatives when using len- ses of 35 mm focal length and longer. A wide-angle diffuser is supplied with the flash- gun to increase the coverage if you wish to use a 28 mm wide-angle lens. A telephoto attachment (identified with a „T“) is inc[...]

16 11. Care and maintenance - T roubleshooting Remove grime and dust with a soft, dry cloth. Do not use cleaning agents as these could damage the plastic parts. 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. For this reason it i[...]
