set to [Auto] in the Rec, menu, When shooting in M mode, or with
[Flash Adjust] set to [Manual], the flash fires with the manually
set adjustments.
• When [Flash Adjust] is set to [Auto], the flash fires twice, A pre-
flash will fire and will be followed by the main flash. The pre-flash
is used by the camera to obtain the sUbject's exposure data so
that the main flash can be set to the optimal intensity for the shot.
• The fastest shutter speed for flash synchronization is 1/250
second. The camera automatically resets the shutter speed to
1/250 second if a faster speed is selected.
• Shots cannot be taken while the flash is charging.
• The flash may take up to approximately 10 seconds to charge in
some cases. Actual times will vary according to usage and the
battery charge.
• The flash exposure and the flash output can be changed
(p.109).
• When shooting with [Slow Synchro] set to [On], camera shake
may become a factor. We recommend the use of a tripod.
• The flash setting is saved when the camera is turned off in the P,
Tv, Av and M shooting modes.
