5.7 TTL flash mode
The mecablitz
The TTL flash mode is a very simple way to achieve excellent flash shots. In this mode exposure readings are taken by a sensor built into the camera which measures the light reach- ing the film through the camera lens (TTL). The electronic control circuit within the camera transmits a stop signal to the mecablitz as soon as the film has been exposed by the cor- rect amount of light, thereby instantly interrupting the flash. The advantage of this flash mode is that all factors in- fluencing correct exposure of the film (filters, change of aper- ture and focal length with zoom lenses, extensions for close- ups, etc.) are automatically taken into account. You need not worry about setting the flash, the camera’s electronic system automatically determines the correct amount of flash light required.
If flash exposure was correct, the “o.k.” exposure confirma- tion lights up.
