Ttl- Flash Mode With Measuring Preflash - Metz MECABLITZ 58 AF-2 Leica Bedienungsanleitung

5.2 TTL- flash mode with measuring preflash

Depending on the camera model, the preflashes precede the main flash
by such a short interval that they practically cannot be distinguished
from the main flash! The preflashes do not contribute to the lighting of
the shot.

Ensure that the contre-jour light source does not shine directly into the
