When shooting in M mode, or with [Flash Adjust] set to [Manual], the flash fires with the manually set adjustments. z When [Flash Adjust] is set to [Auto], the flash fires twice.

The camera automatically resets the shutter speed to 1/250 second if a faster speed is selected. z Shots cannot be taken while the flash is charging. z 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. z The flash exposure and the flash output can be changed (p. 109). z When shooting with [Slow Synchro] set to [On], camera shake may become a factor. We recommend the use of a tripod. z The flash setting is saved when the camera is turned off in the P, Tv, Av and M shooting modes. 66
