USING THE ELECTRONIC FLASH
It is advisable to use a flash when the expo-
sure indicators detect that the light level is
too low, such as indoors, at night time, or in
daylight when the subject is too dark to
provide adequate exposure.
Electronic flash units as well as conventional
flash units using flash bulbs may be utilized.
Your CS-4 has'a hot shoe (Accessory shoe
with built-in flash contact) for "X" synchro-
nization (Fig. 26). Electronic flash units
having a hot-shoe (built-in contact) may be
used without connection cord. As the hot
shoe has "X" type synchronization,  it can be
used with electronic flash at l/60 sec., or at
slower shutter speeds (Fig.27).
The lens aperture is determined by the calcu-
lation table indicated on the flash unit.
Specially designed and developed automatic
flash units are available for your Chinon
CS-4 camera as optional accessories. These
highly advanced electronic flash units permit
carefree flash photography. Look at the
following fantastic flash units by Chinon:
