Flash Synchronization
The Hasselblad 503cx and 500C/M use lenses
from the Hasselblad CF series. These lenses
have built-in leaf shutters with speeds from 1 to
1/500s. Flash synchronization occurs at full
shutter opening via the PC flash terminal.
Electronic flash units can be used at all shutter
speeds, 1 - 1/500.
