1. Function of Micro - Sync
Micro Sync is a device to as-
sure perfect flash ph otography_
Based on the type of b ul b used
and the shutter speed, Micro
Sync automatically adjusts the
timing from the moment the shutter button is pushed
until the bulb flashes, so that a perfectly synchronized
photograph is obtained _
The Time-La8 increases as the Micro Sync dial is
advanced from " 0 " to "30"_ Micro Sync can adjust
the Time-Lag from approximately 2 milli-second up to
15 milli-s econd.
If the Micro Sync dial is set "off " , the Time - Lag is
" 0 "
and the Micro Sync Circuit is not in operation.
