Using the electronic flash
It is advisable to use a flash when the exposure 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 DSL has a
hot shoe (Accessory shoe with built-in flash contact) for " X" synchronization (Fig. 25).
Electronic flash units having a foot with 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 1/60 sec. or at slower shutter
speeds (Fig. 26).
The lens aperture is determined by the calculation table indicated on the flash unit. Specially designed and
developed automatic flash units are available for your Chinon
DSL as optional accessories. This highly carefree flash photography for you. Look at advanced electronics
