LINEAR FLASH MODE (HIGH SPEED SYNCHRONIZATION)
Fully automatic, i.e. camera controlled, linear flash operation is
available with this camera when using correspondingly equipped
Leica system flash units, with all shutter speeds and in aperture
priority and manual exposure modes. The camera activates it
automatically if the selected or calculated shutter speed is faster
than the sync speed of
change does not require the photographer to do anything else.
Important:
The range for HSS flash is significantly lower than for TTL flash.
SELECTING THE SYNC SPEED / THE SYNC SPEED RANGE
Reproduction of the available light is determined by the shutter
speed and the aperture. A fixed setting to the fastest possible
shutter speed for flash operation, the sync time, leads unnecessari-
ly in many situations to a greater or lesser underexposure of all
parts of the subject not directly lit by the flash.
This camera allows you to combine flash operation with the shutter
speed generated in aperture priority mode to subtly change the
lighting conditions for the relevant subject to suit your composi-
tional ideas. You can choose any of five ways of doing this:
