operating instructions for the camera)!

The AF measuring beam is activated by the camera elec- tronics when the ambient lighting conditions are insuffi- cient for automatic focusing. The AF beam projects a striped pattern on to the subject, and the camera uses this pattern to focus automatically. The AF beam has a range of 9 m (with a 50 mm f/1.7 standard lens). Low- speed zoom lenses can significantly curtail the range of the AF measuring beam.

☞Some autofocus cameras have several AF mete- ring fields in addition to the central AF metering area in the camera’s viewfinder. The striped pat- tern of the AF measuring beam only supports the camera’s central AF sensor. Consequently it may be necessary to adjust the central AF sen- sor manually on the camera (see the operating instructions for the given camera and the SCA adapter).

12. Special functions

The special functions of the mecablitz can be called, one after the other, by depressing the Select button, and they can be set, switched off and stored with the setting disk.

12.1Bleep function (acoustic alarm) (Fig. 13)

The bleep function is used to acoustically indicate certain mecablitz functions. It enables the photographer to concentrate fully on the subject without being distrac- ted by the need to observe additional visual status dis- plays!

The bleep function acoustically indicates the following:

•Flash readiness

•Correct flash exposure

•Automatic shut-off of the flash

•Incorrect operation

Acoustic signal after the mecablitz has been switched on:

•A brief (approx. 2 sec.) uninterrupted bleep signal after the mecablitz has been switched on indicates flash readiness.

Bleep signals after exposure:

•A brief (approx. 3 sec.) uninterrupted bleep signal immediately after shooting indicates that exposure was correct and that flash readiness continues. If there is no bleep signal immediately after shooting the pictu- re was underexposed.

•An intermittent bleep signal immediately after shooting confirms correct flash exposure, but flash readiness
