Taking Flash Shots in Each Shooting Mode

Even in <> <> < > modes, E-TTL autoflash is as easy as normal shooting without flash.

(1)Press the shutter button down halfway to have the camera automatically set the shutter speed or aperture value, just as in normal shooting without flash.

Mode	Shutter speed setting	Aperture (flash aperture) setting
(Shutter-priority AE)	Manual (30 to 1/200 sec.)	Auto
(Aperture-priority AE)	Auto (30 to 1/200 sec.)	Manual
(Manual exposure)	Manual (30 to 1/200 sec.)	Manual

∗If <> is set in low-light conditions, a slow shutter speed will be set. Therefore, use a tripod to prevent camera shake.

(2)When you press the shutter button fully, the image will be captured with E-TTL autoflash based on the aperture set by preflash in (1).

(3)The background exposure is determined by the shutter speed and aperture value.

• Flash shooting in <> mode operates the same as in < > mode.

•In the Basic Zone modes, it will be automatic and as easy as flash shooting with the built-in flash.

•With C.Fn-05-3, you can disable the EX-series Speedlite from firing. (→p.147)

•With C.Fn-03-1, the flash sync speed will be fixed at 1/200 sec. in the < > mode. (→p.146)
