AE), <f> (aperture-priority AE), or <a> (manual exposure), you can
execute E-TTL II/E-TTL autoflash suitable for each shooting mode.
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.

be underexposed or overexposed. Adjust the shutter speed until the
aperture value stops blinking.
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

the main subject is obtained with the flash light, while the standard exposure for
f
the background is obtained with a long exposure using a slow shutter speed.

be underexposed or overexposed. Adjust the aperture until the shutter
speed stops blinking.
