In M mode or when [Flash Adjust] is set to [Manual], the flash will
fire with manual adjustments. The maximum flash synchro shutter
speed in this case is 1/250 second. Set the aperture to an
appropriate value according to the flash’s guide number and the
distance to the subject. Check the camera’s ISO sensitivity setting
since the flash’s guide number will change with the ISO value.

When [Flash Adjust] is set to [Manual], the flash output can be

compensation can be adjusted (p. 109).

In M mode or when [Flash Adjust] is set to [Manual], the output of
an externally mounted flash can be adjusted in the flash output
adjustment screen (p. 110). When a Speedlite 550EX, 580EX, a
Macro Ring Lite MR-14EX or a Macro Twin Lite MT-24EX 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, you are
recommended to use the flash’s manual mode. 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. In this situation, the +2 step
setting fires the flash at full intensity.
To shoot with the flash, you are recommended to set the white
balance to the
(Flash) setting.

Since other flashes fire at full strength, set the shutter speed and
aperture accordingly. Set the shutter speed to 1/125 second or

You are recommended to set the white balance to
(Flash) to
