The E-TTL auto flash system can also be used with a Type-A camera set
to

(aperture-priority AE),

T v

(shutter speed-priority AE), or

(manual). Set the FP flash switch to the green dot (normal sync).

■ When you press the shutter button halfway, the shutter speed and aperture setting are

When you press the shutter button completely, the Speedlite fires a test preflash

immediately before the shutter is released. The flash exposure reading obtained with the

preflash is used to calculate the optimum output of the main flash.

The exposure for the background is set with the shutter speed and aperture.

lf flash is used in the DEP (Depth-of-field AE) mode, it will be the same as using

flash in the Program AE mode.
