3. Using Non-dedicated Flash Equipment
This camera’s shutter can synchronize with non-dedicated portable flash
units at up to 1/250 sec. and with studio strobes at up to 1/125 sec.
Before use, test the flash unit at various shutter speeds to make sure it
synchronizes properly with the camera.
●
PC Terminal
Flash units equipped with a synchro cord can be used by connecting the
cord to the camera’s PC terminal. The PC terminal is equipped with a lock
screw to prevent accidental disconnection.
The PC terminal provides only an X-sync contact and synchronizes at all
shutter speeds up to 1/250 sec.
• TTL automatic flash control is not possible.
• Flash units can be connected to both the PC terminal and accessory shoe for multiple
flash setups.
●
We recommend using Canon dedicated speedlites with this
camera.
• Use of flash units (having two or more contacts on the hot shoe) or flash accessories
that are designed for dedicated use with other brands of cameras will not work properly
and may result in damage to your EOS camera.
• Use of flash units of other brands with a trigger circuit voltage in excess of 6 volts DC
may damage your camera. Consult your nearest authorized Canon service facility to
confirm the compatibility.
