• The maximum flash synchro shutter speed is 1/250 second.
• The flash will automatically adjust its output when [Flash
Mode] is set to [Auto].
• When [Flash Mode] is set to [Auto] the flash exposure
compensation can be adjusted. When [Flash Mode] is set to
[Manual], the flash output can be adjusted (p. 149).
• When adjusting flash exposure compensation with both the
camera and the flash (E-TTL mode), the flash settings will
take priority and the camera settings will not function (430EX
only).
• In mode or when [Flash Mode] is set to [Manual], the
output of an externally mounted flash can be adjusted in the
flash output adjustment screen (p. 150). When a Speedlite
430EX is mounted on the camera, you can adjust the flash
output from either the flash or the camera (the flash setting
overrides the camera setting when both are set). To set it
from the flash, use the flash's manual mode. When using
Speed Light 220 EX, adjustment can be made on the camera
only. You can also adjust the flash output even when the
camera is set to the E-TTL automatic flash exposure
compensation mode by changing the flash exposure
compensation setting.
* You can also use the 380EX, 420EX, 550EX and 580EX.
