Metz 34 AF-3 P Autofocus measuring flash, Flash in the individual camera modes, AF red-light beam

6. Flash in the individual camera modes

If the mecablitz is switched on and ready for firing, a flash will be fired each time the camera's shutter is released. The amount of light is controlled by TTL.

Triggering lock (only SF1 and SFx)

On the Pentax SFx and SF1 cameras, the flash will not be fired when the prevailing light is sufficient for an exposure in normal mode. The exposure is then completed with the shutter speed indicated in the display field.

If you intend to take a shot with a shutter speed faster than e.g. 1/250 sec. (depending on the camera model) you must switch off the flashgun.

Refer to the camera's operating instructions for details.

7. Autofocus measuring flash

AF red-light beam

Fig. 5: AF red-light beam

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 shutter release is lightly tou- ched.. The camera’s autofocus system then focu- ses the picture by this striped pattern.
