Canon MARK IV Digital Camera User Manual


 
120
D Flash Photography
With an EZ/E/EG/ML/TL-series Speedlite set in TTL or A-TTL
autoflash mode, the flash can be fired at full output only.
Set the camera’s shooting mode to <a> (manual exposure) or
<f> (aperture-priority AE) and adjust the aperture setting before
shooting.
When using a Speedlite which has manual flash mode, shoot in the
manual flash mode.
Sync Speed
The camera can synchronize with compact, non-Canon flash units at 1/300
sec. or 1/250 sec. or slower. With large studio flash units, since the flash
duration is longer than compact flash units, set the sync speed within 1/125
sec. to 1/30 sec. Be sure to test the flash synchronization before shooting.
PC Terminal
The camera’s PC terminal can be
used with flash units having a sync
cord. The PC terminal is threaded to
prevent inadvertent disconnection.
The camera’s PC terminal has no
polarity. You can connect any sync
cord regardless of its polarity.
Using Non-EX-series Canon Speedlites
Using Non-Canon Flash Units
If the camera is used with a flash unit or flash accessory dedicated to
another camera brand, the camera may not operate properly and
malfunction may result.
Do not connect to the camera’s PC terminal any flash unit requiring 250 V
or more.
Do not attach a high-voltage flash unit on the camera’s hot shoe. It might
not fire.
A flash unit attached to the camera’s hot shoe and a flash unit connected to
the PC terminal can both be used at the same time.
