Simply by setting the camera’s shooting mode to <s> (shutter-priority
AE), <f> (aperture-priority AE), or <a> (manual exposure), you can
execute E-TTL II/E-TTL autoflash suitable for each shooting mode.
If you use the <Z> or <Y> shooting mode, the result will be the same as
using the <d> (Program AE) mode.
1/X sec. is the camera’s maximum flash sync speed.
E-TTL
II/E-TTL Autoflash by Shooting Mode
s
Select this mode when you want to set the shutter speed manually.
The camera will then automatically set the aperture matching the shutter
speed to obtain the standard exposure based on the metering of the camera.
If the aperture value blinks, it means that the background exposure will
be underexposed or overexposed. Adjust the shutter speed until the
aperture value stops blinking.
f
Select this mode when you want to set the aperture manually.
The camera will then automatically set the shutter speed, matching the
aperture to obtain the standard exposure based on the metering of the camera.
For low-light scenes, a slow sync speed will be used to obtain the standard
exposure for both the main subject and background. The standard exposure for
the main subject is obtained with the flash light, while the standard exposure for
the background is obtained with a long exposure using a slow shutter speed.
Since a slow shutter speed will be used for low-light scenes, using a
tripod is recommended.
If the shutter speed blinks, it means that the background exposure will
be underexposed or overexposed. Adjust the aperture until the shutter
speed stops blinking.
a
Select this mode if you want to set both the shutter speed and aperture
manually.
Standard exposure of the main subject is obtained with the flash light. The
exposure of the background changes according to the shutter speed and
aperture combination you set.
