C.Fn I -5
The AEB shooting sequence and white balance bracketing sequence can
be changed.
0: 0, -, +
1: -, 0, +
AEB
0 : Standard exposure
- : Decreased exposure - : Blue bias
+ : Increased exposure
C.Fn I -6
0: Disable
1: Enable (Tv/Av)
This works in the shutter-priority AE (s) and aperture-priority AE (f)
modes. When the subject's brightness changes erratically and the
correct autoexposure cannot be obtained, the camera will change the
exposure setting automatically to obtain a correct exposure.
C.Fn I -7
0: Auto
Normally, the sync speed will be set automatically within 1/250 sec. to
30 sec. High-speed sync can also take effect.
1: 1/250-1/60 sec. auto
When flash is used with aperture-priority AE (f), this prevents a slow
flash-sync speed from being set automatically in low-light conditions. It
is effective for preventing subject blur and camera shake. However,
while the subject will be properly exposed with the flash, the background
will come out dark.
2: 1/250 sec. (fixed)
The flash-sync speed is fixed to 1/250 sec. This more effectively
prevents subject blur and camera shake than with setting 1. However,
the background will come out darker than with setting 1.
