Flash With Other Modes - Canon SPEEDLITE 220EX Instructions Manual

Flash with Other Modes

The E-TTL autoflash control
system can be used with Type A
cameras set to the P (Program
AE), Av (Aperture-priority AE),
Tv (Shutter speed-priority AE),
or M (Manual) mode.
■ When you press the shutter button
halfway, the shutter speed and
aperture settings are displayed in
the viewfinder as in any AE mode.
Shutter Speed and Aperture Settings According to Mode
Mode Shutter Speed
P Automatically set(1/60sec to 1/X sec.)*
Av Automatically set(30sec to 1/X sec.)
Tv Manually set(30sec to 1/X sec.)
M Manually set(buLb to 1/X sec.)
• Manually set refers to the setting by the user. Automatically set refers to the set-
ting computed by the Speedlite 220EX and camera.
• 1/X sec. refers to the camera maximum sync speed (see page 40).
* 1/90 sec. only for the EOS REBEL G, and EOS 500N cameras.
■ The Speedlite 220EX fires a test preflash immediately before the shutter is
released. After obtaining an initial flash exposure reading with the preflash, the
Speedlite 220EX fires the main flash to provide optimum flash exposure.
■ The exposure for the background is determined with the shutter speed and
aperture settings.
■ The E-TTL indicator on the rear of the Speedlite 220EX lights automatically
when the power is turned on and the shutter button is pressed halfway.
• The shutter speed and aperture are set automatically when the camera
is set to the P mode as in fully-automatic flash operations.
• If the flash is used in the DEP (Depth-of-field AE) mode or the
Programmed Image Control modes, it will be similar to using flash in
the P mode.
