e6: Auto Bracketing (Mode M)
This option determines which settings are affected when [AE &
flash] or [AE only] is selected for Custom Setting e5 in manual
exposure mode.
Flash bracketing is performed only with i-TTL or AA flash control. If
a setting other than [Flash only] is selected and the flash is not
used, ISO sensitivity will be fixed at the value for the first shot,
regardless of the setting selected for ISO sensitivity auto control
(pg. 96).
